X-raying the Stellar Graveyard: Mapping Supernova Remnants with eROSITA
Abstract: Supernova remnants (SNRs), the leftovers of violent stellar explosions, drive rapid shock waves heating the surrounding interstellar medium to millions of degrees. The resulting X-ray emission not only produces striking images, but also encodes vital information about the nucleosynthetic products of the explosion, shock physics, and interactions with the surrounding medium.
Launched in 2019, the SRG/eROSITA mission has carried out the most sensitive all-sky X-ray survey to date, providing an unprecedented homogeneous view of SNRs across the Galaxy and Magellanic Clouds.
In this talk, I will highlight how eROSITA has advanced our understanding of both individual SNRs and entire populations. As a "discovery machine", eROSITA has revealed new SNRs missed in previous pointed observations, such as the high-latitude remnant Hoinga. Further, its uniform coverage of large regions enables population studies, as exemplified by the identification of numerous new SNR candidates in the Large Magellanic Cloud. Finally, eROSITA excels at mapping extended nearby SNRs such as Vela and Puppis A, which are too large for other X-ray telescopes, enabling detailed studies of shock heating and ejecta composition.
I will conclude with a brief discussion of how NewAthena will further transform our studies of the "stellar graveyard", both regarding population studies and the physics of individual SNRs.
