Investigating new super-soft sources in the Magellanic Cloud System

The Magellanic Clouds are an ideal site to study super-soft X-ray sources given their moderate and well known distances with low Galactic foreground absorption. In the course of the eROSITA all-sky surveys the MCs are scanned frequently. This provides the unique opportunity to detect new SSS in the full Magellanic System as already demonstrated during the first survey. We propose three triggered XMM observations of 20 ks each of new or unexplored SSS in the MS. Our goal is to study their spectral and temporal properties in detail and identify their nature by combining the existing multi-wavelength follow-up facilities we have with the SALT transients collaboration and the GROND on the ESO/MPG telescope.



Details on Observing Strategy and Trigger Criteria
New or transient super-soft sources in the Magellanic Cloud system with luminosity exceeding 10E35 erg/s. Observation to be performed within 5 days after trigger.
