Gamma-Ray Polarimetry of Transient Sources with POLAR
, 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 ...

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, 2009 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.

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

Fermi-LAT RESULTS ON GALACTIC PLANE γ-RAY TRANSIENT SOURCES [PDF]
The Twelfth Marcel Grossmann Meeting, 2012 The Large Area Telescope on the Fermi gamma-ray Space Telescope provides unprecedented sensitivity for all-sky monitoring of gamma-ray activity. It has detected a few Galactic sources, including 2 gamma-ray binaries and a microquasar. In addition, it is an adequate telescope to detect other transient sources.

The Astrophysical Journal, 2023 Relativistic electrons are an essential component in many astrophysical sources, and their radiation may dominate the high-energy bands. Inverse Compton (IC) emission is the radiation mechanism that plays the most important role in these bands. The basic

Evidence for Two Distinct Populations of Kilonova-associated Gamma-Ray Bursts
The Astrophysical Journal Letters, 2023 Identification of gamma-ray burst (GRB) progenitors based on the duration of their prompt emission ( T _90 ) has faced several roadblocks recently. Long-duration GRBs (with T _90 > 2 s) have traditionally been thought to be originating from the collapse ...

The Astrophysical Journal Letters, 2023 GRB 221009A has been referred to as the brightest of all time (BOAT). We investigate the veracity of this statement by comparing it with a half century of prompt gamma-ray burst observations.
