Short Time-scale Gamma-Ray Variability of Blazars and EGRET Unidentified Sources
S. D. Bloom, D. J. Thompson, R. C. Hartman +1
We have begun to examine the EGRET database for short term variations in the fluxes of blazars and unidentified sources at high Galactic latitude. We find that several AGN show pre…
EGRET Observations of the Extragalactic Gamma Ray Emission
P. Sreekumar
The all-sky survey in high-energy gamma rays (E30 MeV) carried out by the Energetic Gamma Ray Experiment Telescope (EGRET) aboard the Compton Gamma-Ray Observatory provides a un…
Fast Variations of Gamma-Ray Emission in Blazars
Stefan J. Wagner, Corinna von Montigny, Martin Herter
The largest group of sources identified by EGRET are Blazars. This sub-class of AGN is well known to vary in flux in all energy bands on time-scales ranging from a few minutes (in…
Multi-wavelength Observations of 3C 273 in 1993-1995
C. von Montigny
We present the results of the multi-wavelength campaigns on 3C 273 in 1993-1995. During the observations in late 1993 this quasar showed an increase of its flux for energies greate…
EGRET Observations of Pulsars
P. L. Nolan, the EGRET team
EGRET can now study six pulsars since the recent detection of PSR B1951+32. Careful analysis of the three brightest pulsars shows that gamma rays are emitted through essentially th…
EGRET Observations of Gamma Rays from Point Sources with Galactic Latitude +10(degrees) < b < +40(degrees)
P. L. Nolan
The EGRET instrument aboard the Compton Gamma Ray Observatory (CGRO) has completed the first all-sky survey in high-energy gamma rays and has repeatedly viewed selected portions of…
