Gamma-Ray Polarimetry of Transient Sources with POLAR [PDF]

open access: green, 2022
Polarization measurements of the gamma-ray component of transient sources are of great scientific interest, they are however, also highly challenging. This is due to the typical low signal to noise and the potential for significant systematic errors. Both issues are made worse by the transient nature of the events which prompt one to observe a large ...

Precise source location of the anomalous 1979 March 5 gamma-ray transient [PDF]

open access: greenThe Astrophysical Journal, 1982
Refinements in the source direction analysis of the observations of the unusual gamma ray transient are presented. The final results from the interplanetary gamma ray burst network produce a 0.1 arc sq. min. error box. It is nested inside the initially determined 2 arc sq min. source region. This smaller source location is within both the optical and X-

The HAWC Gamma-Ray Observatory: Sensitivity to Steady and Transient Sources of Gamma Rays [PDF]

open access: green, 2013
The High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory is designed to record air showers produced by cosmic rays and gamma rays between 100 GeV and 100 TeV. Because of its large field of view and high livetime, HAWC is well-suited to measure gamma rays from extended sources, diffuse emission, and transient sources.

Neutrino alert systems for Gamma Ray Bursts and transient astronomical sources [PDF]

open access: greenNuclear 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.

Variable optical/infrared counterpart to the transient gamma-ray source J0109+6134 [PDF]

open access: bronzeAstronomy & Astrophysics, 2013
Context. We investigate the optical/infrared counterpart to the flaring gamma-ray source J0109+6134, which is believed to be a blazar seen through the Galactic plane.Aims. The original aim of this work was to confirm the previously proposed optical counterpart by means of studying its temporal behaviour.

Effects of dead time losses on terrestrial gamma ray flash measurements with the Burst and Transient Source Experiment [PDF]

open access: bronzeJournal of Geophysical Research: Space Physics, 2010
Measurements from the Burst and Transient Source Experiment (BATSE) instrument on the Compton Gamma Ray Observatory (CGRO) are the only ones where characteristics of single terrestrial gamma ray flashes (TGFs) have been obtained thus far. However, it has been reported that the measurements suffer from significant dead time losses which complicates the ...

THE INTERPLANETARY NETWORK SUPPLEMENT TO THE BURST AND TRANSIENT SOURCE EXPERIMENT 5B CATALOG OF COSMIC GAMMA-RAY BURSTS [PDF]

open access: bronzeThe Astrophysical Journal Supplement Series, 2011
We present Interplanetary Network localization information for 343 gamma-ray bursts observed by the Burst and Transient Source Experiment (BATSE) between the end of the 4th BATSE catalog and the end of the Compton Gamma-Ray Observatory (CGRO) mission, obtained by analyzing the arrival times of these bursts at the Ulysses, Near Earth Asteroid Rendezvous
