How do gamma ray bursts happen
WebMar 29, 2024 · Although gamma-ray bursts can arise from the merger of two neutron stars, as Fermi and LIGO/Virgo saw in a famous 2024 event, this class of events almost always produces short-period gamma-ray bursts. Gamma-ray bursts are very bright as observed from Earth despite their typically immense distances. An average long GRB has a bolometric flux comparable to a bright star of our galaxy despite a distance of billions of light years (compared to a few tens of light years for most visible stars). Most of this energy is released in gamma rays, although some GRBs have extremely luminous optica…

We’ve got this beam of radiation pointing directly … WebWe present photometric and spectroscopic observations of the extraordinary gamma-ray burst (GRB) 221009A in search of an associated supernova. Some past GRBs have shown bumps in the optical light curve that coincide with the emergence of supernova spectral features, but we do not detect any significant light-curve features in GRB 221009A, nor do …
WebOct 21, 2024 · Even for a long-duration burst, it was unusually extended. Another blast of gamma rays was spotted by the Neil Gehrels Swift Observatory, another orbiting set of telescopes designed to observe bursts. WebThe gamma radiation from a burst within a few kiloparsecs would quickly deplete much of the Earth's protective ozone layer, allowing an increase in solar UVB radiation reaching the surface. This radiation is harmful to life, damaging DNA and causing sunburn. In addition, NO2 produced in the atmosphere would cause a decrease in visible sunlight ...
