After initial claims and a long hiatus, it is now established that several binary stars emit high-
(0.1–100 GeV) and very high-energy (> 100 GeV) gamma rays. A new class has emerged …

For nearly a century, more mass has been measured in galaxies than is contained in the
luminous stars and gas. Through continual advances in observations and theory, it has …

Fewer than a dozen gamma-ray pulsars were known when the Fermi Gamma-ray Space
Telescope was launched on 2008 June 11, and the extent and diversity of the population …

We present the third Fermi Large Area Telescope (LAT) source catalog (3FGL) of sources in
the 100 MeV–300 GeV range. Based on the first 4 yr of science data from the Fermi Gamma …

The detection of high-energy cosmic neutrinos as cosmic messengers has been an
important goal of astroparticle physics. Being stable, electrically neutral particles, high …

We report the discovery of an extended very-high-energy (VHE) gamma-ray source around
the location of the middle-aged (207.8 kyr) pulsar PSR J 0622+ 3749 with the Large High …

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 …

We analyze the parsec-scale jet kinematics from 2007 June to 2013 January of a sample of
γ-ray bright blazars monitored roughly monthly with the Very Long Baseline Array at 43 GHz …

Most of the celestial γ rays detected by the Large Area Telescope (LAT) on board the Fermi
Gamma-ray Space Telescope originate from the interstellar medium when energetic cosmic …
