Two Stage Phase Transition in Two Higgs Models
David Land, Eric Carlson
We present a mechanism in which models with two Higgs fields can undergo a two stage phase transition as the temperature falls. The first stage is a conventional second order (or w…
Putting Things Back Where They Belong: Tracing Cosmic-Ray Injection with H2
Eric Carlson, Tim Linden, Stefano Profumo
At present, all physical models of diffuse Galactic gamma-ray emission assume that the distribution of cosmic-ray sources traces the observed populations of either OB stars, pulsar…
Improving the Sensitivity of Gamma-Ray Telescopes to Dark Matter Annihilation in Dwarf Spheroidal Galaxies
Eric Carlson, Dan Hooper, Tim Linden
The Fermi-LAT collaboration has studied the gamma-ray emission from a stacked population of dwarf spheroidal galaxies and used this information to set constraints on the dark matte…
Improved Cosmic-Ray Injection Models and the Galactic Center Gamma-Ray Excess
Eric Carlson, Tim Linden, Stefano Profumo
Fermi-LAT observations of the Galactic Center (GC) have revealed a spherically- symmetric excess of GeV gamma rays extending to at least 10 deg from the dynamical center of the Gal…
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…
A Clustering Analysis of the Morphology of the 130 GeV Gamma-Ray Feature
Eric Carlson, Tim Linden, Stefano Profumo +1
Recent observations indicating the existence of a monochromatic gamma-ray line with energy ~130 GeV in the Fermi-LAT data have attracted great interest due to the possibility that…
Cosmic Ray Protons in the Inner Galaxy and the Galactic Center Gamma-Ray Excess
Eric Carlson, Stefano Profumo
A gamma-ray excess over background has been claimed in the inner regions of the Galaxy, triggering some excitement about the possibility that the gamma rays originate from the anni…
Antihelium from Dark Matter
Eric Carlson, Adam Coogan, Tim Linden +3
Cosmic-ray anti-nuclei provide a promising discovery channel for the indirect detection of particle dark matter. Hadron showers produced by the pair-annihilation or decay of Galact…
Gravitino Dark Matter and Flavor Symmetries
Angelo Monteux, Eric Carlson, Jonathan Cornell
In supersymmetric theories without R-parity, the gravitino can play the role of a decaying Dark Matter candidate without the problem of late NLSP decays affecting Big Bang Nucleosy…
When Dark Matter interacts with Cosmic Rays or Interstellar Matter: A Morphological Study
Eric Carlson, Stefano Profumo
Excess emission over expected diffuse astrophysical backgrounds in the direction of the Galactic center region has been claimed at various wavelengths, from radio to gamma rays. Am…
Testing the dark matter origin of the WMAP-Planck Haze with radio observations of Spiral Galaxies
Eric Carlson, Dan Hooper, Tim Linden +1
If the Galactic WMAP radio haze, as recently confirmed by Planck, is produced by dark matter annihilation or decay, similar diffuse radio halos should exist around other galaxies w…
