Chandra Observations of the Collisional Ring Galaxy NGC 922
A. H. Prestwich, J. L. Galache. T. Linden, V. Kalogara +5
In this paper we report on Chandra observations of the starburst galaxy NGC 922. NGC 922 is a drop-through ring galaxy with an expanding ring of star formation, similar in many res…
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…
Are Lines From Unassociated Gamma-Ray Sources Evidence For Dark Matter Annihilation?
Dan Hooper, Tim Linden
Very recently, it was pointed out that there exists a population of gamma-ray sources without associations at other wavelengths which exhibit spectral features consistent with mono…
Exploring the Nature of the Galactic Center Gamma-Ray Source with the Cherenkov Telescope Array
Tim Linden, Stefano Profumo
Observations from multiple gamma-ray telescopes have uncovered a high energy gamma-ray source spatially coincident with the Galactic center. Recently, a compelling model for the br…
The Morphology of Hadronic Emission Models for the Gamma-Ray Source at the Galactic Center
Tim Linden, Elizabeth Lovegrove, Stefano Profumo
Recently, detections of a high-energy gamma-ray source at the position of the Galactic center have been reported by multiple gamma-ray telescopes, spanning the energy range between…
Gamma-ray Lines in the Fermi Data: is it a Bubble?
Stefano Profumo, Tim Linden
Recently, tentative evidence for an excess of gamma rays at energies around 130 GeV has been reported from analyses of data from the Fermi Large Area Telescope (LAT). The excess is…
The Isotropic Radio Background and Annihilating Dark Matter
Dan Hooper, Alexander V. Belikov, Tesla E. Jeltema +3
Observations by ARCADE-2 and other telescopes sensitive to low frequency radiation have revealed the presence of an isotropic radio background with a hard spectral index. The inten…
Anisotropies in the diffuse gamma-ray background measured by the Fermi LAT
M. Ackermann, M. Ajello, A. Albert +134
The contribution of unresolved sources to the diffuse gamma-ray background could induce anisotropies in this emission on small angular scales. We analyze the angular power spectrum…
