Illuminating the 130 GeV Gamma Line with Continuum Photons
Speaker(s): Mariangela Lisanti
Abstract: There is evidence for a 130 GeV gamma-ray line at the Galactic Center in the Fermi Large Area Telescope data. Dark matter candidates that explain this feature should also annihilate to Standard Model particles, resulting in a continuous spectrum of photons. To study this continuum, we analyze the Fermi... read more

A Flow of Dark Matter Debris: Exploring New Possibilities for Substructure
Speaker(s): Mariangela Lisanti
Abstract: Tidal stripping of dark matter from subhalos falling into the Milky Way produces narrow, cold tidal streams as well as more spatially extended "debris flows'' in the form of shells, sheets, and plumes.Here we focus on the debris flow in the Via Lactea II simulation, and show that this incompletely ... read more
