Gamma Rays from Clusters and Groups of Galaxies: Cosmic Rays versus Dark Matter
Tesla E. Jeltema, John Kehayias, Stefano Profumo
Clusters of galaxies have not yet been detected at gamma-ray frequencies; however, the recently launched Fermi Gamma-ray Space Telescope, formerly known as GLAST, could provide the…
Fitting the Gamma-Ray Spectrum from Dark Matter with DMFIT: GLAST and the Galactic Center Region
Tesla E. Jeltema, Stefano Profumo
We study the potential of GLAST to unveil particle dark matter properties with gamma-ray observations of the Galactic center region. We present full GLAST simulations including all…
Searching for Dark Matter with X-ray Observations of Local Dwarf Galaxies
Tesla E. Jeltema, Stefano Profumo
A generic feature of weakly interacting massive particle (WIMP) dark matter models is the emission of photons over a broad energy band resulting from the stable yields of dark matt…
The X-ray Properties of Moderate-redshift Galaxy Groups Selected by Association with Gravitational Lenses
C. D. Fassnacht, D. D. Kocevski, M. W. Auger +5
We present results from a systematic investigation of the X-ray properties of a sample of moderate redshift (0.3<z<0.6) galaxy groups. These groups were selected not by traditional…
X-ray Properties of Intermediate-Redshift Groups of Galaxies
T. E. Jeltema, J. S. Mulchaey, L. M. Lubin +2
We have undertaken a multiwavelength project to study the relatively unknown properties of groups and poor clusters of galaxies at intermediate redshifts. In this paper, we describ…
X-ray Selected Intermediate-Redshift Groups of Galaxies
John S. Mulchaey, Lori M. Lubin, Chris Fassnacht +2
We present spectroscopic confirmation of nine moderate redshift galaxy groups and poor clusters selected from the ROSAT Deep Cluster Survey. The groups span the redshift range z=0.…
