Description
The Andromeda Galaxy (M31) is a nearby (∼780 kpc) galaxy similar to our own Milky Way. Observational evidence suggests that it resides in a large halo of dark matter (DM), making it a good target for DM searches. We present a search for gamma rays from M31 using data from the LHAASO Observations. With its wide field of view and constant monitoring, LHAASO is well-suited to search for DM in extended targets like M31. No DM annihilation or decay signal was detected for DM masses from 10 TeV to 1 EeV in the $b\overline{b}, t\overline{t}, \tau^{+}\tau^{-}, \mu^{+}\mu^{-} $ and $W^{+}W^{-}$ channels. Therefore we present our preliminary limits on those processes.
