SUMMARY:S&A Colloquium: Jennifer West (Dominion Radio Astrophysical Observatory)
DESCRIPTION:Is the heliopause seen in radio synchrotron emission?\n\nAbstract: \n\nDiffuse radio synchrotron emission originating in the Milky Way fills the entire sky\, even at high Galactic latitudes. The emission is highly linearly polarised\, and comes from high energy CRs moving in the Galaxy’s magnetic field. Planck has measured the orientation of this emission and has mapped the magnetic field pattern across the sky\, however\, we do not know if the origin of the pattern is distant (tracing the large-scale magnetic field) or nearby (tracing the Local Bubble\, a massive superbubble where our Sun now resides). The reality is the emission must originate at a wide range of distances. In this talk\, I will present evidence that some of this emission has its origin in the interaction between the heliopause and the very local interstellar magnetic field. The emission is polarised\, and traces the local interstellar magnetic field as it wraps around the heliosphere at the heliopause boundary\, which is related to the Sun’s motion through space\, and which has previously been revealed through a bright ribbon of emission detected by NASA’s Interstellar Boundary Explorer (IBEX). \n\nPlease note that the event timezone is AEDT (UTC+11 hrs) \n\n \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Anna Ivleva (Observatory of Munich / Ludwig Maximilian University)
DESCRIPTION:Odd Radio Circles (ORCs): probing radio features at group scales with simulations\n\nAbstract: \n\nExtragalactic radio astronomy has proven to be immensely useful in the study of high energy particle physics by constraining the acceleration of cosmic ray electrons and their subsequent synchrotron emission. Investigations of galaxy clusters have shown to be particularly fruitful\, since such massive environments grant favourable conditions for efficient particle acceleration via merger driven shocks. Yet\, a new class of radio objects discovered only a few years ago imposes the question if also merger shocks in less massive systems can accelerate CR electrons to GeV energies. Specifically\, a growing number of observations is pointing towards the existence of ringlike features around small galaxy groups  and even Milky Way-like objects\, accordingly titled Odd Radio Circles (ORCs). Recent works have proposed that these could be interpreted as radio analogs to the merger shocks observed in more massive systems. However\, ORCs are appearing in a colder and less magnetized medium than the radio features in galaxy clusters\, challenging particle acceleration  mechanisms in more constraining environments. Now\, by interpreting multiple observed ORCs at different stages as an evolutional time sequence and comparing them to simulations of such systems\, one can infer underlying properties of these unique features\, while simultaneously testing the limits of diffusive shock acceleration (DSA). To this end\, I will present the first of its kind magnetohydrodynamical simulation of a galaxy group\, utilising on-the-fly treatment of spectral cosmic rays. I will study the emerging radio features and discuss both similarities and differences to the observed counterparts. Finally\, I will review the relative importance of DSA in the formation of ORCs compared to galactic sources of high energy particles\, such as supernovae and AGN. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Dan Rybarczyk (University of Wisconsin-Madison)
DESCRIPTION:New constraints on CO-dark molecular gas properties in the diffuse ISM: Insights from 21cm and 3mm absorption observations\n\nAbstract: \n\nThe evolution of the multiphase interstellar medium (ISM) drives galaxy evolution. The transition from diffuse atomic gas to denser molecular clouds sets the initial conditions for star formation\, so plays a critical role in this evolution. However\, since molecular hydrogen (H2) is invisible in many diffuse environments\, observational constraints on the atomic-to-molecular transition remain limited. CO emission is often used to trace H2\, but in the diffuse ISM\, a significant fraction of H2 is not associated with any CO emission (the “CO-dark” molecular gas). Thankfully\, HCO+ absorption at 3mm is an excellent tracer of diffuse molecular gas — with a stable abundance and formation/survival at low column density\, HCO+ is a reliable probe of the H2 column density in the diffuse ISM. Here we report observations of HI\, HCO+\, and CO in absorption toward five diffuse lines of sight. In all of these directions\, we detect a kinematically broad\, CO-dark signature in HCO+ absorption that is associated with nearly all the cold atomic gas in these directions. We constrain the CO abundances in these directions\, which are consistent with chemical model predictions and account for the non-detection of CO. In fact\, we show that CO emission or absorption are unlikely to be detected where N(H2) < 7E19 cm^-2\, while HCO+ absorption is readily detected for N(H2) > ~fewE18 cm^-2\, opening an important window on the HI-to-H2 transition. The diffuse\, CO-dark gas associated with broad HCO+ absorption has systematically different properties\, including a lower fraction of cold atomic gas and a lower molecular fraction\, than CO-bright gas. These observations therefore offer insights on the HI-to-H2 transition that are inaccessible with CO observations.  I will briefly discuss future work aimed at uncovering the spatial structure of this diffuse\, partially-molecular gas — key to understanding the physics of this critical stage of galaxy evolution. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:Colearnium: Duy Nguyen (CSIRO)
DESCRIPTION:A Single-Chip Wideband Digital Receiver for the Australia Telescope Compact Array Upgrade\n\nThis week Duy Nguyen will present on “Modernizing Legacy: Wrapping a 25+ Year Computational Fluid Dynamics Codebase“. \n\n\n\nModernizing Legacy: Wrapping a 25+ Year Computational Fluid Dynamics Codebase \n\nAuthors: Duy Nguyen\, Tisham Dhar\, Peter Wang\, Jean-Michel Perraud\, Klaus Joehnk.Computational Fluid Dynamics (CFD) is the science of using numerical analysis and data structures to solve many processes influencing fluid behavior. CFD requires many complex mathematical representations through various ODE and PDE solvers\, and has traditionally been written in Fortran or C++\, mostly for their speed in doing massively parallel computations\, such as handling array operations and object-oriented features. As such\, those codebases have a long-standing legacy in scientific computing\, and many established CFD codes are written in them. However\, as time goes on\, we witness the popularity of a new generation of codebases such as Python\, which stems from its simplicity\, versatility\, and strong community. Extensive libraries and frameworks make Python a popular choice for many developers and scientists alike. It is\, however\, not a preferred language for core CFD code due to performance limitations and its difficulties with parallelization. This talk explores modernizing a 25+ year-old C++ CFD model\, essential for simulating lake conditions\, particularly for predicting temperature variations and algal bloom dynamics\, by wrapping it with [C-interop] for seamless Python interoperability. Beyond integration\, we leverage [Optuna]\, a powerful hyperparameter optimization framework\, to fine-tune models efficiently\, transitioning from manual parameter tuning on a laptop to a distributed\, scalable workflow powered by Dask Distributed and JupyterHub. This transformation enables automated hyperparameter optimization across many lakes in Australia\, helping researchers investigate trends in tuning parameters and derive deeper environmental insights.Attendees will gain insights into:– Wrapping legacy C++ water quality models with CFFI for Python-driven analysis.– Automating and scaling hyperparameter tuning using Optuna across multiple lake ecosystems.– Utilizing Dask Distributed and JupyterHub to accelerate environmental simulations.– Extracting insights from hyperparameter trends to refine large-scale water quality predictions. For researchers\, engineers\, and data scientists working in environmental modeling\, this session provides practical strategies for modernizing legacy systems\, scaling model optimization\, and enhancing predictive accuracy without sacrificing scientific integrity. \n\n\n\nPlease let me know if you’re willing to present at a future co-learnium or have requests for specific talks\, thanks! \n\nKind regards\, \n\nSamuel (On behalf of the co-learnium organisers) \n\nTeams meeting link below: \nTeams Meeting\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Michael Busch (NRAO)
DESCRIPTION:OH as a Tracer of “CO-Dark” Gas in the Interstellar Medium Near and Far\n\nAbstract: \n\nMolecular clouds are the birthplace of stars. It is unfortunate then that the most abundant interstellar molecule\, molecular hydrogen (H2)\, is practically invisible in cold molecular clouds (T<100K). Astronomers typically use the second most abundant molecule\, carbon monoxide (CO)\, to trace the bulk distribution of H2 in our galaxy and many others because of its relative brightness and abundance. CO observations alone\, however\, fail to trace a significant amount of molecular gas\, known as “CO-dark” molecular gas. In this talk\, I will review the observational evidence for the existence of a significant amount of “CO-dark” gas in the galaxy\, then recount the efforts in the 2010s to use OH with the Green Bank Telescope (GBT) to observe the “CO-dark” gas in the Outer galaxy (Busch et al. 2019\, 2021). Then I will present recent results on an extremely sensitive pilot survey for 18cm OH emission towards the southern disk of the Andromeda Galaxy\, in which trace the large-scale galactic “CO-Dark” molecular gas with the GBT (Busch 2024). A follow-up Andromeda survey is presented. I will discuss recent efforts in combining HCO+ absorption in the diffuse ISM with OH emission to understand the properties of diffuse molecular gas in the ISM and conclude on future work with collaborators in Australia regarding OH as a tracer of “CO-dark” gas. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Kelly Gourdji (ATNF)
DESCRIPTION:Revisiting GW170817 at milliarcsecond scale: high-precision constraints on jet geometry and Hubble’s constant\n\nAbstract: \n\nThe historic detection of gravitational waves from the electromagnetically bright binary neutron star merger GW170817 enabled the first standard siren measurement of Hubble’s constant (H0). The accuracy and precision of this measurement depends crucially on how well the merger inclination angle is constrained\, given its strong covariance with luminosity distance. Modeling the light curve of the jet’s afterglow provides constraints on inclination\, but is highly dependent on the similarly uncertain jet opening angle. Past studies have improved on this by invoking high-resolution radio observations\, obtained through very long baseline interferometry\, to constrain the viewing angle. In this talk\, I will present our Bayesian visibility-plane model-fitting framework that provides a more informed and robust measurement of the viewing geometry of GW170817\, by including all relevant data\, robustly handling systematic uncertainties\, rigorously sampling model parameter space and using new hydrodynamical jet models. We extend our framework to fit for H0 directly\, and consider various plausible peculiar velocity corrections to present a new and improved standard siren measurement of H0. Strikingly\, we find our result to be in better agreement with one of the two precise and independent H0 measurements that are famously in tension. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Ben Stappers (Jodrell Bank / University of Manchester)
DESCRIPTION:Hunting FRBs and Transients with MeerTRAP \n\nAbstract: \n\nMeerTRAP (more TRAnsients and Pulsars) is a fully commensal program running on the MeerKAT telescope to search for transients including FRBs and radio emitting neutron stars. It utilises the excellent sensitivity and wide bandwidth of the MeerKAT telescope to enable it to see faint/distant sources both inside and outside our Galaxy. I will describe the MeerTRAP experiment including our real time analysis systems and our transient buffer which allows us to localise FRBs. I will present some highlights of the FRBs that we have discovered so far including some which have been localised and have associated (high) host galaxy redshifts. I will also present some results on the two repeating FRBs that we have identified. MeerTRAP works with the MeerLICHT optical telescope to undertake simultaneous observations and I will present the latest results from those studies. MeerTRAP has also discovered more than 100 new Galactic transients and I will summarise their properties and discuss some of the particularly interesting sources\, especially those with longer than typical pulsar spin periods. I will also present the detection of a particularly interesting Galactic transient. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Taïssa Danilovich (Monash University)
DESCRIPTION:The effect of evolved star binaries on circumstellar astrochemistry and dust formation\n\nAbstract: \n\nLow- and intermediate-mass stars disgorge their outer layers during the asymptotic giant branch (AGB) phase\, one of the last stages of their lives. Material containing newly-formed elements and a variety of dust and molecules streams out of them in what we call a stellar wind. Studies resolving the extended circumstellar environments of AGB stars have revealed spirals\, discs and bipolar outflows\, with the shaping of the gas attributed to interactions with a companion. However\, most of these companions are not directly observed\, because their light is so strongly attenuated by the dust created around the AGB star. Astrochemistry is the study of molecules\, dust and the chemical reactions that link them in astrophysical environments. I will discuss new methods that combine theoretical astrochemistry with observations to allow us to deduce the nature of the companion stars in binary systems with AGB stars. From this we can begin to understand how companion stars affect the length of the AGB phase. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Ravi Subrahmanyan (CSIRO)
DESCRIPTION:Radio discovery of Cosmic Dawn\n\nAbstract \n\nAs First Light from the First Stars transforms the universe from Dark Ages into Cosmic Dawn\, the thermal history may be traced in redshifted 21-cm from neutral hydrogen in the gas.  Efforts to build radiometers  to detect this faint signal are yielding results of significance to the theory\, thus constraining the starlight of the earliest galaxies and their impact on the gas.  I will present the progression in astrophysical constraints that have resulted from radiometers deployed in remote sites in India – at the Timbaktu collective\, in the trans-Himalayan plateau and floated on remote lakes.   Progress in precision has led to building of a GINAN radiometer in CSIRO\, which has been trialed at the Inyarrimanha Ilgari Bundara\, the Murchison Radio-astronomy Observatory in remote radio-quiet Western Australia\, with an SKA-Low antenna element. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Emma Carli (Swinburne University)
DESCRIPTION:Are neutron stars outside our galaxy any different?\n\nAbstract: \n\nThe TRAPUM  (TRAnsients and PUlsars with MeerKAT) collaboration has so far doubled the extragalactic radio pulsar population with a survey of nearby galaxies.The completed Small Magellanic Cloud (SMC) galaxy survey revealed a large proportion of neutron stars in this star-forming dwarf are young\, including new Pulsar Wind Nebulae systems\, as well as giant pulsar glitches and Vela-like behaviour. The prolific Large Magellanic Cloud survey is still under way.This prompted a new project to study the whole Neutron Star population of the SMC as a nearby template for the high-redshift\, low-metallicity\, star-forming dwarf galaxies that are producing hyperactive Fast Radio Bursts\, exotic supernovae\, gamma-ray bursts\, and large High-Mass X-ray Binary populations. I will present the implications of this project and our initial investigations. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Aline Vidotto (Observatory of Leiden University\, Netherlands)
DESCRIPTION:Exo-space weather: The impact of stellar activity and outflows on exoplanets\n\nAbstract:  \n\nActivity of cool dwarf stars can reveal itself in the form of high-energy radiation (eg\, enhanced X-ray coronal emission\, flares) and particles (eg\, winds\, coronal mass ejections). Together\, these phenomena shape the space weather around (exo)planets. Because most of the known exoplanets have significantly closer orbital distances than solar system planets\, they are often embedded in much harsher particle and radiation environments\, leading to stronger interactions between the exoplanet and its surrounding environment.In this talk I will present some of our recent modelling efforts investigating how stellar activity and outflows can induce and shape atmospheric escape in exoplanets. I will also present the other side of the story: how (and when) exoplanets can affect the host star\, in particular\, focusing on radio emission that exoplanets can induce in the coronae of stars. Altogether\, these interactions can help us characterise the system\, putting physical constraints on planetary properties (such as their still elusive magnetic fields) as well as properties of the winds of planet hosting stars. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Chenoa Tremblay (SETI / Breakthrough)
DESCRIPTION: Large-Scale Technosignatures Searches and the Stuff that Makes it Work\n\nAbstract: The search for technological life beyond Earth is a large-scale search for unidentified spectral-temporal signatures. So far\, most searches for these electromagnetic “technosignatures” have required dedicated time on telescopes or the use of archival data. A new digital back-end for the Karl G. Jansky Very Large Array (VLA) and the MeerKAT telescopes has been developed to continuously observe the sky during observations and process the data in real-time to detect these unique signals. The systems named COSMIC (the Commensal Open-source Multimode Interferometric Cluster) and BL USE employ Ethernet packet protocols\, real-time calibration strategies\, coherent and incoherent beamforming\, and open-source Doppler search algorithms to complete this goal at high-time and high-frequency resolutions. In collaboration with NRAO and the VLA sky-survey team\, we are recording during epoch 4 of the survey for one of the first all-sky searches for extraterrestrial signals\, with the sensitivity improvements allowed by such a powerful telescope. The purpose of this talk is to present the hardware and software structures of COSMIC and BL USE\, how they function\, and our first results. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:S&A Colloquium: Iris de Ruiter (University of Sydney)
DESCRIPTION:The Variables and Slow Transients Extragalactic survey: exploring radio transients with ASKAP \n\nAbstract:  \n\nThe Variables and Slow Transients (VAST) survey on the Australian Square Kilometre Array Pathfinder (ASKAP) is transforming our view of the dynamic radio sky. For decades\, searches for radio transients typically yielded only a handful of detections. Today\, wide-field\, sensitive telescopes like ASKAP have transformed our view of the dynamic radio sky. With VAST\, we are monitoring millions of sources and building light curves on an unprecedented scale. \n\nIn this talk I will present an update on the extragalactic component of VAST. I will outline our observing strategy\, data processing and quality control\, and describe how we build and interpret light curves. Finally\, I will showcase results from the 100 most variable sources in our current sample—just the beginning of what this rich dataset can reveal. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory

SUMMARY:Colearnium: David Skellern
DESCRIPTION:A commentary on who really ‘invented Wi-Fi’\n\nThis week David Skellern will present on “A commentary on who really ‘invented Wi-Fi’“. \n\n———————————————————————————————————————————————————– \n\nDr David Skellern\, AO FTSE FIEEE HonFIEAust \n\nDr David Skellern worked in radio astronomy for 10 years and taught electronics at the University of Sydney and Macquarie Universities for 16 years before coming to prominence in the IT sector through Radiata\, which he co-founded in 1997. Building on joint research at Macquarie University and CSIRO\, Radiata demonstrated the world’s first chip-set implementation of the 54Mbit/s lEEE 802.11a high speed WLAN standard. Radiata was sold in 2001 to Cisco Systems Inc\, where Dr Skellern was Director\, Technology of the Wireless Networking Business Unit until 2004.  \n\nHe was appointed to the Board of National ICT Australia in 2003 and was Chief Executive Officer 2005-2010.   \n\nHe was a Non-executive Director (NED) of the Board of the Capital Markets CRC (CMCRC) 2004-2019 and Board Chair 2013-2019\, then Chair of RoZetta Institute Ltd (formerly CMCRC) 2019-2022. He was also a NED of the Boards of eight RoZetta Group companies.  \n\nDr Skellern is a NED and Board Chair of Quasar Satellite Technologies Pty Ltd\, the Semiconductor Sector Service Bureau (S3B)\, and the International Centre for Radio Astronomy Research (ICRAR)\, and a NED of Trovio Pte Ltd. He advises several early-stage technology companies. He is a Visiting Professor at Imperial College London and an Adjunct Professor at Macquarie University.   \n\nWho Really Invented Wi-Fi? \n\nIn the early 1990s\, a joint CSIRO/Macquarie University team conceived\, developed and implemented the linked technologies that made it possible to scale wireless LANs to ever-higher speeds as chip technology advanced. This pioneering work shaped the global success of Wi-Fi.  \n\nA Sydney Morning Herald article on March 25 this year mixed valid concerns on science funding innovation with selective history and emphasis on disputes to downplay and reframe the originality and significance of these Australian achievements on high speed WiFi.  \n\nThis talk sets the record straight\, separating fact from myth\, and showing how high-speed WiFi was truly born. \n\n———————————————————————————————————————————————————– \n\n \n\nPlease let me know if you’re willing to present at a future co-learnium or have requests for specific talks\, thanks! \n\nKind regards\, \n\nSamuel (On behalf of the co-learnium organisers) \n\nTeams meeting link below: \nTeams Meeting\nOrganiser\n\nEvent details\nDownload iCal\nCategory
