Description
The Large Magellanic Cloud (LMC) is a large and nearby satellite galaxy of the Milky Way, which underwent multiple recent star formation episodes. Due to its low inclination and foreground absorption, the properties of the hot phase of its interstellar medium (ISM) can be ideally probed via its diffuse soft X-ray emission. This, in combination with deep available exposure due to the location of the LMC close to the SRG/eROSITA survey pole, makes the LMC an ideal target for studying the interplay of the hot and cold ISM phases as well as the ISM heating and enrichment through massive stars, using eROSITA and multiwavelength data.
In this contribution, we will present the results of an X-ray morphological and spectral analysis campaign of the ISM in the LMC, based on the full available eROSITA All-Sky Survey, complemented with radio, infrared, and optical data.
We will discuss the anticorrelation of the hot and cold ISM phases, caused by both X-ray absorption and macroscopic inhomogeneities in their distribution. Further, we will show to what extent the distribution of the hot ISM phase in the LMC can be linked to massive stars. Finally, we will present evidence for star-formation-fueled outflows in the east of the LMC, traced by filaments in X-rays and optical line emission, enhanced elemental abundances, and possibly X-ray synchrotron emission from accelerated cosmic rays.
