The Burst and Transient Source Experiment (BATSE) Earth Occultation Catalog of Low‐Energy Gamma‐Ray Sources [PDF]
The Astrophysical Journal Supplement Series, 2004 The Burst and Transient Source Experiment (BATSE), aboard the Compton Gamma Ray Observatory (CGRO), provided a record of the low-energy gamma-ray sky (∼20-1000 keV) between 1991 April and 2000 May (9.1 yr).

Discovery of a Nonblazar Gamma-Ray Transient Source Near the Galactic Plane: GRO J1838−04 [PDF]
The Astrophysical Journal, 1997 We report the discovery of a remarkable γ-ray transient source near the Galactic plane, GRO J1838-04. This source was serendipitously discovered by EGRET in 1995 June with a peak intensity of ~(4 ± 1) × 10-6 photons cm-2 s-1 (for photon energies larger ...

Neutrino alert systems for Gamma Ray Bursts and transient astronomical sources [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2008 GRBs are the most energetic events in the Universe, associated with the death of massive stars (core-collapse supernovae) or the merging of neutron stars or black holes. Discovered in the early 1970s, their cosmological origin was demonstrated only in 1997, when the first distance was measured.

Searching for Short-Timescale Transients in Gamma-ray Telescope Data
Galaxies, 2023 Astrophysical sources show variability in their emissions over a range of timescales, with transients such as fast radio bursts (FRBs) and magnetar giant flares (MGFs) showing variability on timescales as short as a few milliseconds.

Transient X-ray sources in the field of the Unidentified Gamma-Ray Source TeV J2032+4130 in Cygnus [PDF]
Astrophys.SpaceSci.309:29-33,2007, 2006 We present an analysis of Chandra ACIS observations of the field of TeV J2032+4130, the first unidentified TeV source, detected serendipitously by HEGRA. This deep (48.7 ksec) observation of the field follows up on an earlier 5 ksec Chandra director's discretionary observation.
