Gamma-Ray Binaries Revealed
(American Association For The Advancement Of Science, 2012-01-13)
Recent ground- and space-based telescopes that detect high-energy photons from a few up to hundreds of gigaelectron volts (GeV) have opened a new window on the universe. However, because of the relatively poor angular ...
High-energy gamma-ray production in microquasars
(Soc Brasileira Fisica, 2007-12)
A hadronic model for gamma-ray production in microquasars is presented. Microquasars are galactic binary systems with jets, which have, presumably, hadronic components. We consider a microquasar formed by a neutron star ...
GeV Emission in the Region of the Supernova Remnant G51.26+0.11
(2021-11-02)
The supernova remnant G51.26+0.11 was recently discovered and little is known about its properties and environment. Using data from the Fermi Large Area Telescope we study the GeV emission seen in the direction of G51.26+0.11 ...
High-mass microquasars and low-latitude gamma-ray sources
(EDP Sciences, 2004-12)
Population studies of unidentified EGRET sources suggest that there exist at least three different populations of galactic gamma-ray sources. One of these populations is formed by young objects distributed along the galactic ...
Search for gamma-ray emission from star-forming galaxies with Fermi LAT
(2016-08)
Recent studies have found a positive correlation between the star-formation rate of galaxies and their gamma-ray luminosity. Galaxies with a high star-formation rate are expected to produce a large amount of high-energy ...

Gravitational microlensing of gamma-ray blazars
(Wiley Blackwell Publishing, Inc, 2003-12)
We present a detailed study of the effects of gravitational microlensing on compact and distant γ -ray blazars. These objects have γ -ray-emitting regions that are small enough to be affected by microlensing effects produced ...
