Search for extended gamma-ray emission from the Virgo galaxy cluster with Fermi-LAT
M. Ackermann, M. Ajello, A. Albert +118
Galaxy clusters are one of the prime sites to search for dark matter (DM) annihilation signals. Depending on the substructure of the DM halo of a galaxy cluster and the cross secti…
Search for gamma-ray emission from the Coma Cluster with six years of Fermi-LAT data
LAT Collaboration, Y. Rephaeli
We present results from γ-ray observations of the Coma cluster incorporating 6 years of Fermi-LAT data and the newly released {\emph{Pass 8}} event-level analysis. Our analysis of…
Local H~{\sc i} emissivity measured with the {\it Fermi}-LAT and implications for cosmic-ray spectra
Jean-Marc Casandjian
Cosmic-ray (CR) electrons and nuclei interact with the Galactic interstellar gas and produce high-energy rays. The -ray emission rate per hydrogen atom, called emissivity, p…
Fermi-LAT Observations of High- and Intermediate-Velocity Clouds: Tracing Cosmic Rays in the Halo of the Milky Way
L. Tibaldo, S. W. Digel, J. -M. Casandjian +10
It is widely accepted that cosmic rays (CRs) up to at least PeV energies are Galactic in origin. Accelerated particles are injected into the interstellar medium where they propagat…
The Fermi-LAT model of interstellar emission for standard point source analysis
Jean-Marc Casandjian
We describe the development of the model for interstellar gamma-ray emission that is the standard adopted by the LAT team and is publicly available. The model is based on a linear…
The Third Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope
M. Ackermann, M. Ajello, W. Atwood +139
The third catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT (3LAC) is presented. It is based on the third Fermi-LAT catalog (3FGL) of sources detected between 100…
Fermi Large Area Telescope Third Source Catalog
LAT Collaboration
We present the third Fermi Large Area Telescope source catalog (3FGL) of sources in the 100 MeV-300 GeV range. Based on the first four years of science data from the Fermi Gamma-ra…
