Multi-instrument Search for Gamma-Ray Counterpart of X-Ray Transients Detected by EP/WXT

open access: yesThe Astrophysical Journal Letters
As a soft X-ray imager with an unprecedentedly large field of view, Einstein Probe (EP)/Wide-field X-ray Telescope (WXT) has detected many (fast) X-ray transients, whose nature is very intriguing.

Historical Fermi All-sky Variability Analysis of Galactic Flares

open access: yesThe Astrophysical Journal
The Fermi All-sky Variability Analysis (FAVA) provides a photometric alternative for identifying week-long gamma-ray flares across the entire sky while being independent of any diffuse Galactic or isotropic emission model.

Radio Morphology of Gamma-Ray Sources: Double-lobed Radio Sources

open access: yesThe Astrophysical Journal
The extragalactic γ -ray sky is dominated by relativistic jets aligned to the observer’s line of sight, i.e., blazars. A few of their misaligned counterparts, e.g., radio galaxies, are also detected with the Fermi-Large Area Telescope (LAT), albeit in a ...

The GAMMA-400 gamma-ray telescope characteristics. Angular resolution and electrons/protons separation [PDF]

open access: yes, 2014
The measurements of gamma-ray fluxes and cosmic-ray electrons and positrons in the energy range from 100 MeV to several TeV, which will be realized by the specially designed GAMMA-400 gamma-ray telescope, concern with the following broad range of ...
