Synchrotron Emission from Dark Matter in Galactic Subhalos. A Look into the Smith Cloud.

Speaker
Martin Vollmann, Technische Universität München (Germany)

Host
Roberto Lineros, IFIC

Abstract

One of the key predictions of the “WIMP” paradigm for Dark Matter (DM) is that DM particles can annihilate into charged particles. These annihilations will proceed in e.g. Galactic subhalos such as dwarf Galaxies or, as recently pointed out, high velocity clouds such as the “Smith” cloud. In this talk I will argue that among the several messengers of the DM annihilations occurring in the Smith cloud, radio signals stand out. I will also discuss the applicability and the prospects of these ideas in big data radio surveys such as LOFAR.
