X-raying the Magellanic Clouds: A roadmap from XMM to eROSITA
The Magellanic Clouds are an ideal site to study X-ray source population
of a galaxy including supernova remnants, high mass X-ray binaries
(HMXBs) and super-soft sources. This is facilitated by their
well-determined distances and low foreground absorption conducive for
performing detailed studies. The population of HMXBs in the Magellanic
Clouds is especially overabundant owing to the relatively recent
star-formation history of these tidally interacting galaxies. However,
only a small-fraction of the entire Magellanic Cloud System (which
covers nearly 200 square degrees on the sky) was covered in the X-ray
regime, until recently. eROSITA onboard SRG has now completed its first
two all-sky surveys and has roughly doubled the number of X-ray sources
discovered over the last 60 years history of X-ray astronomy. This has
also allowed a complete coverage of the Magellanic Cloud system for the
first time in X-rays (0.2-10 keV) with unprecedented sensitivity. The
talk will present the X-ray source population of the Magellanic Clouds,
especially HMXBs as studied from the XMM-Newton to the recent eROSITA
all-sky surveys. Some unique discoveries including HMXBs found in their
natal supernova remnants will also be discussed in this regard.
