Population Study of SNRs in the Large Magellanic Cloud

Most of the stars end their life with an explosion called supernovae (SNe). This event expels the stellar interior in the surrounding which enrich the interstellar medium (ISM) with metals. The supernova remnants (SNRs) are the residual of these explosions and their emission is visible in different wavelength from radio, optical and X-ray band. The emission from SNRs can be studied to infer information about the SNe it self as well as the property of the surrounding ISM. The best laboratory for the study of the population of SNRs in a galaxy is the Large Magellanic Cloud (LMC). Indeed the LMC is the nearest star-forming galaxy which is outside the Galactic plane that causes low absorption along the line of sight. The eRosita telescopes are the best instrument available to make such a survey thanks to the large field of view and the high sensitivity in the softer part of the X-ray emission. We present the initial results from eRosita data collected to inspect the SNR population in the LMC in the X-ray band. We made a spectral analysis of the brightest SNR in the sample and compared the spectral result with the previous results from XMM-Newton and Chandra observation. The eRosita data also allowed us to investigate the very recent SNR candidate detected in the radio band using ASKAP interferometry.
