SUMMARY:S&A Colloquium: Albert Zijlstra (University of Manchester)
DESCRIPTION:Stars that merge in the Milky Way\n\nAbstract\n\n Stellar explosions come in two main varieties. At the top end are the supernovae\, visible to cosmological distances but which may be missed when occurring in our own Milky Way. The second group are the novae\, frequent events but much fainter. But some transients fall in between\, too bright and long-lasting for novae but too faint for supernovae. Although rare\, there are some historical observations of such events in the Milky Way. This talk will discuss two such eruptions. The first is CK Vul\, which exploded in 1670 as a 3rd magnitude nova\, re-appeared in 1671 and again in 1672. The second event is the supernova of 1181 which was (only) as bright as Saturn but remained visible for 180 days. Both objects are understood as stellar merger events; SN1181 is a possible Type Iax supernova\, the least understood of the major supernovae. \n\n The image above shows the Pa 30 nebula\, which we identify as the remnant of the supernova explosion of the year 1181. The left panel shows a false colour image of Pa 30 where red stands for an image taken with the WISE satellite at 11 micron\, green for WISE 22 micron\, and blue for ultraviolet emission mapped by the GALEX satellite; the contours show X-ray emission mapped with the XMM-Newton satellite. The majority of the X-ray emission originates from the core of the nebula while WISE sees the larger nebula. The panel on the right shows an image of the [O IIII] emission from the nebula\, taken with the 2.1-m telescope at Kitt Peak [O III] image. The green cross in the center of the image marks the location of the central star. Both panels are to the same scale. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Jordan Collier (AusSRC/CIRA)
DESCRIPTION:Clouds over middle-earth: using ilifu to combine the MeerKAT and the EMU for ORCs\n\nAbstract\n\n Combining ASKAP’s EMU survey and MeerKAT enables complementary science; ASKAP’s large FoV enables the discovery of new/rare types of objects\, like Odd Radio Circles (ORCs)\, while MeerKAT’s sensitivity enables deep follow up of such objects. I will speak about both instruments and how they are being used to open up new phase spaces of discovery\, with a particular focus on the spectral indices and polarisation of ORCs\, and my experience using these telescopes within the clouds across the continents of middle-earth! As an essential part of this research\, I will speak about a number of tools and systems that have been developed or adopted to deal with the PB scale of MeerKAT data at the Inter-University Institute for Data Intensive Astronomy (IDIA). I will present a number of these tools and underlying systems\, deployed on IDIA’s ilifu facility\, including those for storage\, processing\, visualisation\, and data transfers. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Ophelia Renaud (INSA-IETR\, France)
DESCRIPTION:Design and programming of heterogeneous and high-performance computing systems in astronomy\n\nAbstract\n\n In this presentation\, I address the difficult problem inherent in SKA of deploying complex astronomical applications under development on efficient target architectures that have not yet been built. Resource allocation in such scenarios has a significant impact on multiple factors such as latency\, memory\, energy\, and cost among others. Solutions such as rapid prototyping make it possible to reliably simulate and generate efficient code for this purpose. At INSA-IETR\, we are developing the PREESM rapid prototyping tool to automate and accelerate this process. The tool is based on numerous thesis and internship projects as well as numerous collaborations such as Rising Stars\, which is the subject of my presentation. This presentation will give an overview of the project’s progress in our team. I propose methods based on the SDF (Synchronous Dataflow) model and clustering techniques to facilitate the deployment of applications on complex architectures such as CPUs\, GPUs\, and FPGAs on one or more machines. By providing a quick and easy solution to this NP-hard problem\, our methods significantly improve the efficiency of astronomical application deployment. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia
