Gamma ray bursts 2020
WebAug 24, 2012 · Gamma-ray bursts (GRBs) are the most extreme explosive events in the universe. The initial (prompt) phase lasts typically less than 100 s and has an energy content of ~10 51 ergs, giving a luminosity that is a million times larger than the peak electromagnetic luminosity of the bright emission from an exploding-star supernova. The … WebFeb 23, 2024 · This paper presents microsatellite spacecraft payload study for prompt observation of transient astrophysical objects in X-ray energy range. By combining telescope concepts and miniaturized detectors, the small spacecraft will be able to probe the X-ray temporal emissions of bright events such as Gamma-Ray Bursts (GRBs), X-ray …

In this paper, we collected 6289 GRBs (from GRB 910421 to GRB 160509A) from the literature, including their prompt emission, afterglow, and host galaxy properties. We hope to use this large sample to reveal the intrinsic properties of GRBs.
