SUMMARY:Kristine Spekkens Colloquium
DESCRIPTION:Gas-Rich Galaxies as Cosmological Probes\n\n \n\nAbstract \n\nThe atomic gas (HI) content of nearby galaxies provides important insight into how they form and evolve within the standard cosmology. In this talk\, I will highlight some of my group’s recent progress towards building statistical samples of gas-rich galaxies to use as cosmological probes. I will first focus on how sensitive HI searches in optically-selected dwarf and ultra-diffuse galaxy candidates are a powerful tool for measuring their structure and constraining formation models. I will then describe how the widefield WALLABY survey\, now underway on the Australian SKA Pathfinder (ASKAP)\, is delivering the first spatially-resolved populations of HI disks for comparison with cosmological predictions. This work paves the way for probing HI disks across cosmic time using the SKA when it comes online towards the end of this decade. \nAdd a button here\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Bryan Scott (CIERA\, Northwestern University)
DESCRIPTION:Prospects for Fundamental Physics from Line Intensity Mapping\n\nAbstract \n\nLine Intensity Mapping (LIM) is a technique for quickly performing surveys of large volumes at many frequencies but at low spatial resolution. These large survey volumes make LIM a promising method for constraining fundamental physics\, such as beyond wCDM cosmology or extensions of Einstein Gravity in the coming decade. I will begin this talk with a presentation of LIM and synergies with photometric and spectroscopic galaxy surveys\, in particular the Vera C. Rubin Observatory Legacy Survey of Space & Time (LSST) and surveys with the Subaru Observatory Prime Focus Spectrograph (PFS). After introducing forecasting results for fundamental physics with LIM\, I will discuss how astrophysical uncertainties pose barriers to interpretation and conclude with an overview of prospects for machine learning and improved statistical methods to meet these challenges \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Vincenzo Galluzzi (IRA-INAF\, Bologna)
DESCRIPTION:From Data Archives to Science Gateways: examples of INAF-supported radio facilities.\n\nAbstract \n\nData archives are now rapidly evolving from simple repositories to sophisticated science gateways\, facilitating data discovery\, access\, retrieval\, visualization\, processing\, interoperability (with data at different wavelengths or from different messengers)\, and reuse. This transformation is driven by the increasing volume and complexity of data generated by modern radio astronomy facilities\, which offer unprecedented potential for scientific discovery. \n\nINAF has been at the forefront of this evolution\, actively embracing Open Science principles\, through supporting various initiatives promoted by the International Virtual Observatory Alliance (IVOA) in developing and implementing new standards. From the perspective of the radio astronomical facilities I am working with\, I will present some examples of e-infrastructures or projects at various scales\, including: \n\n\nThe INAF Radio Telescope Data Archive\, a newly operational archive providing access to a wealth of radio astronomical data. In such a context\, I will also briefly address the INAF contribution to the IVOA Radio Interest Groups (RIG)\, which recently proposed an extension of the ObsCore Data Model (ObsCore DM) for bolstering the discovery of radio data.\n\n\n\nThe Additional Representative Images for Legacy (ARI-L) project\, leaded by the Italian node of the ALMA Regional Centre: this project reprocessed ALMA data from earlier cycles (2-4) in order to support archival science projects\, hence adding value to the ALMA Science Archive (ASA) itself.\n\n\n\nThe deployment of the Italian node of the SKA Regional Centre Network (SRCNet): the Team Orange established by the SRC Steering Committee (SRCSC) has been working on a prototype for data visualization\, and recently changed its focus towards deployment activities\, since Italy will host one of the first 9 nodes of the SRCNet.\n\nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia
