The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars
LAT Collaboration
The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…
Constraints on the Galactic Halo Dark Matter from Fermi-LAT Diffuse Measurements
LAT collaboration, M. Ackermann, M. Ajello +139
We have performed an analysis of the diffuse gamma-ray emission with the Fermi Large Area Telescope in the Milky Way Halo region searching for a signal from dark matter annihilatio…
Gamma-Ray and Parsec-Scale Jet Properties of a Complete Sample of Blazars From the MOJAVE Program
M. L. Lister, M. Aller, H. Aller +142
We investigate the Fermi LAT gamma-ray and 15 GHz VLBA radio properties of a joint gamma-ray- and radio-selected sample of AGNs obtained during the first 11 months of the Fermi mis…
The radio/gamma-ray connection in Active Galactic Nuclei in the era of the Fermi Large Area Telescope
M. Ackermann, M. Ajello, A. Allafort +144
We present a detailed statistical analysis of the correlation between radio and gamma-ray emission of the Active Galactic Nuclei (AGN) detected by Fermi during its first year of op…
A change in the optical polarization associated with a gamma-ray flare in the blazar 3C 279
LAT Collaboration, members of the 3C 279 multi-band campaign
It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet po…
Constraints on Cosmological Dark Matter Annihilation from the Fermi-LAT Isotropic Diffuse Gamma-Ray Measurement
LAT collaboration, A. A. Abdo, M. Ackermann +147
The first published Fermi large area telescope (Fermi-LAT) measurement of the isotropic diffuse gamma-ray emission is in good agreement with a single power law, and is not showing…
