Abstract

In this seminar, we will provide a comprehensive overview of current insights into diverse phenomena within the hot and energetic universe. Topics covered span the investigation of extreme accretion processes in ultra-luminous sources, the characterization of compact objects within supernova remnants, and an in-depth exploration of accreting white dwarfs, particularly in the context of those nearing the Chandrasekhar mass limit and the genesis of ultra-compact binaries. We will discuss the results and its implications on population studies and globular scaling relations of accreting binaries in external galaxies. The impact on multi-messenger astrophysics will also be discussed.

The talk will further feature an exploration of the groundbreaking SRG/eROSITA all-sky X-ray mission, highlighting its sensitivity and impact. We will conclude by providing insights into future prospects, including upcoming and next-generation space missions poised to further advance our understanding of the hot and energetic universe.

Chandreyee Maitra is a scientist in the high energy group of the Max Planck Institute for Extraterrestrial Physics. Her research interests revolve around end points of stellar evolution, population studies in external galaxies, and space missions focused to observe the universe in X-rays. She is also actively working and is involved in many current and future multi-wavelength projects such as VISTA Magellanic Cloud survey, 4MOST and is the co-chair of the Magellanic Cloud working group in SDSS V. She is leading the pipeline and data processing activities of the SRG eROSITA German collaboration. She is also a member of the calibration and operations team for the eROSITA mission and was formerly associated with the XMM-Newton Survey Science Centre (SSC) team and its calibration activities.
