"Prospective dark matter annihilation signals from the Sagittarius Dwarf Spheroidal" - Venville et al. (2024)
Alan Duffy
My extraordinary student Thomas Venville undertook an exhaustive study into the use of a nearby galaxy (that is currently being consumed by our Milky Way galaxy) as a potential source of gamma-radiation that could be from the self-annihilation of that dark matter that surrounds this galaxy. The challenge as Thomas conclusively demonstrated is that these signals appear both weaker than previously estimated, and together with the fact that the galaxy has recently been shown to emit gamma-rays of astrophysical origin, complicate the use of it in indirect DM detection searches.
