The Second Catalog of Flaring Gamma-Ray Sources from the Fermi All-sky Variability Analysis [PDF]
, 2016 We present the second catalog of flaring gamma-ray sources (2FAV) detected with the Fermi All-sky Variability Analysis (FAVA), a tool that blindly searches for transients over the entire sky observed by the Large Area Telescope (LAT) on board the Fermi ...

Fermi establishes classical novae as a distinct class of gamma-ray sources [PDF]
Science, 2014 Gamma-ray novas may be garden variety When astronomers detected gamma rays from the nova V407 Cyg, an explosive mass transfer from a red giant onto a white dwarf, they found it surprising enough.

Differential Source Count for Gamma-Ray Bursts [PDF]
The Astrophysical Journal, 2021 Abstract Different forms of long gamma-ray burst (GRB) luminosity functions are considered on the basis of an explicit physical model. The inferred flux distributions are compared with the observed ones from two samples of GRBs, Swift and Fermi GBM.

Revealing x-ray and gamma ray temporal and spectral similarities in the GRB 190829A afterglow. [PDF]
Science, 2021 Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic sources followed by fading afterglow emission, are associated with stellar core collapse events.

Unidentified EGRET Sources and the Extragalactic Gamma-Ray Background [PDF]
, 2006 The large majority of EGRET point sources remain to this day without an identified low-energy counterpart. Whatever the nature of the EGRET unidentified sources, faint unresolved objects of the same class must have a contribution to the diffuse gamma-ray

PARKES RADIO SEARCHES OF FERMI GAMMA-RAY SOURCES AND MILLISECOND PULSAR DISCOVERIES [PDF]
, 2015 In a search with the Parkes radio telescope of 56 unidentified Fermi-Large Area Telescope (LAT) gamma-ray sources, we have detected 11 millisecond pulsars (MSPs), 10 of them discoveries, of which five were reported by Kerr et al.

The Gamma-ray Window to Intergalactic Magnetism [PDF]
Universe, 2021 One of the most promising ways to probe intergalactic magnetic fields (IGMFs) is through gamma rays produced in electromagnetic cascades initiated by high-energy gamma rays or cosmic rays in the intergalactic space.
