Galactic Astrophysics with LISA



The Milky Way, while extensively studied, still conceals much about its fossil population of stellar remnants, including white dwarfs, neutron stars, and black holes, as these objects often remain out of reach for electromagnetic telescopes. Yet they become accessible when they form ultra-short-period binaries, which emit gravitational radiation. In my talk, I will showcase the potential of the upcoming Laser Interferometer Space Antenna (LISA) for Galactic studies, emphasising its ability to characterise ultra-short-period binary populations across the entire Milky Way. I will outline how the LISA mission could contribute to solving some of the persistent questions in our field, such as the nature of Type Ia supernova progenitors or the origin of the excess gamma-ray emission observed towards the Galactic Centre.

Wednesday 11th February at 3.45pm, C4 Physics – Astronomy Seminar
Jessica Pilling (Sussex)

Getting Ready for the Future of X-ray Astronomy



In this talk, I will present recent results from the X-ray Cluster Science (XCS) collaboration, preparing for the X-ray support to upcoming cosmology surveys. First, I will present my project on the X-ray properties of galaxy clusters observed by XMM-Newton, eROSITA, and the Dark Energy Survey. I will describe the cross-calibration of galaxy cluster temperatures and luminosities enabled by the open-source XGA and DAXA software packages, applied to eROSITA data for the first time. I will then highlight complementary work , led by Paul Giles, characterising DES clusters in deep eROSITA survey regions. Finally, I will discuss the prospects for future X-ray–optical scaling relation studies with the upcoming 4MOST spectroscopic survey.
