The DESI Transients Survey: Legacy Classifications and Methodology
Xander J. Hall, Antonella Palmese, Segev BenZvi +56
We present the first systematic spectroscopic observations of extragalactic transients from the Dark Energy Spectroscopic Instrument (DESI), as part of the DESI Transients Survey p…
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…
Analysis of the Very Inner Milky Way Dark Matter Distribution and Gamma-Ray Signals
V. Gammaldi, V. Avila-Reese, O. Valenzuela +1
We analyze the possibility that the HESS gamma-ray source at the Galactic Center could be explained as the secondary flux produced by annihilation of TeV Dark Matter (TeVDM) partic…
Effect of Black Holes in Local Dwarf Spheroidal Galaxies on Gamma-Ray Constraints on Dark Matter Annihilation
Alma X. Gonzalez-Morales, Stefano Profumo, Farinaldo S. Queiroz
Recent discoveries of optical signatures of black holes in dwarf galaxies indicates that low-mass galaxies can indeed host intermediate massive black holes. This motivates the asse…
