Searching for Dark Matter Decay within the Virgo Cluster with the HAWC Observatory

The Virgo Cluster is a galaxy cluster located roughly 16 Mpc from the Milky Way composed of more than 1300 gravitationally bound elliptical and spiral galaxies. Due to its expected high dark matter (DM) content and close proximity to Milky Way, the Virgo Cluster is one of the best candidates for searches for DM decay. The High Altitude Water Cherenkov (HAWC) Observatory has a wide field of view and observes 1-100 TeV gamma-rays and cosmic rays. It is an ideal instrument for DM searches within extended objects such as the Virgo Cluster. We perform searches for DM decay using 1128 days of HAWC data. No statistically significant signal is detected. Thus, we report lower limits on the DM decay lifetime for 1-100 TeV DM mass range.
