Description
The search for Dark Matter (DM) signatures in the X-ray sky remains essential for testing models of decaying keV dark matter, such as sterile neutrinos and axions. With its coverage and survey depth, eROSITA provides unprecedented sensitivity to keV dark matter. We present a search for X-ray lines using all available data from the eROSITA Data Release 1 (DR1), and interpret the result in the context of DM decay. The analysis covers the entire western hemisphere of the sky, and demonstrate the potential of future eROSITA data releases for probing dark matter in the X-ray range sky.
