Gamma-ray flaring activity from the gravitationally lensed blazar PKS 1830-211 observed by Fermi LAT
The Fermi LAT Collaboration, A. A. Abdo, M. Ackermann +126
The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope routinely detects the highly dust-absorbed, reddened, and MeV-peaked flat spectrum radio quasar PKS 1830…
The spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV
The Fermi LAT collaboration, M. Ackermann, M. Ajello +142
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a res…
Temporal Correlations Between Optical and Gamma-ray Activity in Blazars
Daniel P. Cohen, Roger W. Romani, Alexei V. Filippenko +4
We have been using the 0.76-m Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory to optically monitor a sample of 157 blazars that are bright in gamma rays, being detec…
