On the origin of the gamma-ray emission from Omega Centauri: Milisecond pulsars and dark matter annihilation
Javier Reynoso-Cordova, Oleg Burgueño, Alex Geringer-Sameth +3
We explore two possible scenarios to explain the observed gamma-ray emission associated with the atypical globular cluster Omega-Centauri: emission from millisecond pulsars (MSP) a…
Astrophysical explanations of suspected dark matter signals in dwarf galaxies
Alex Geringer-Sameth, Savvas M. Koushiappas, Matthew G. Walker +3
We present methods to assess whether gamma-ray excesses towards Milky Way dwarf galaxies can be attributed to astrophysical sources rather than to dark matter annihilation. As a ca…
CF2 White Paper: Status and Prospects of The VERITAS Indirect Dark Matter Detection Program
Andrew W. Smith, Ralph Bird, James Buckley +11
In this white paper, submitted as a part of Snowmass 2013 (subgroup CF2), we examine the current status and future prospects of the VERITAS indirect dark matter detection program.…
Dark matter line search using a joint analysis of dwarf galaxies with the Fermi Gamma-ray Space Telescope
Alex Geringer-Sameth, Savvas M. Koushiappas
We perform a joint analysis of dwarf galaxy data from the Fermi Gamma-ray Space Telescope in search of dark matter annihilation into a gamma-ray line. We employ a novel statistical…
