Updated Constraints on Asteroid-Mass Primordial Black Holes as Dark Matter
Nolan Smyth, Stefano Profumo, Samuel English +3
Microlensing of stars places significant constraints on sub-planetary-mass compact objects, including primordial black holes, as dark matter candidates. As the lens' Einstein radiu…
Where do the 3.5 keV photons come from? A morphological study of the Galactic Center and of Perseus
Eric Carlson, Tesla Jeltema, Stefano Profumo
We test the origin of the 3.5 keV line photons by analyzing the morphology of the emission at that energy from the Galactic Center and from the Perseus cluster of galaxies. We empl…
Cosmic Ray-Dark Matter Scattering: a New Signature of (Asymmetric) Dark Matter in the Gamma Ray Sky
Stefano Profumo, Lorenzo Ubaldi
We consider the process of scattering of Galactic cosmic-ray electrons and protons off of dark matter with the radiation of a final-state photon. This process provides a novel way…
Measurement of the Cosmic Ray e+ plus e- spectrum from 20 GeV to 1 TeV with the Fermi Large Area Telescope
LAT Collaboration
Designed as a high-sensitivity gamma-ray observatory, the Fermi Large Area Telescope is also an electron detector with a large acceptance exceeding 2m^2 sr at 300 GeV. Building on…
Neutralino relic density in supersymmetric GUTs with no-scale boundary conditions above the unification scale
Stefano Profumo
We investigate SU(5) and SO(10) GUTs with vanishing scalar masses and trilinear scalar couplings at a scale higher than the unification scale. The parameter space of the models, fu…
Twisted Eguchi-Kawai Reduced Chiral Models
Stefano Profumo, Ettore Vicari
We study the twisted Eguchi-Kawai (TEK) reduction procedure for large-N unitary matrix lattice models. In particular, we consider the case of two-dimensional principal chiral model…
