A Weird Gamma-Ray Burst Has Been Spotted, And It

WebGamma ray bursts. Gamma ray bursts (GRBs) were originally proposed as a possible source of extragalactic cosmic rays because the energy required to produce the observed flux of cosmic rays was similar their typical luminosity in γ-rays, and because they could accelerate protons to energies of 10 20 eV through diffusive shock acceleration.

WebJan 13, 2024 · On April 15 2024, a giant wave of X-rays and gamma rays lasting only a fraction of a second swept across the solar system, triggering detectors on NASA and European spacecraft. The GRB 200415A event was a giant flare from a magnetar, a type of city-sized neutron star that boasts the strongest magnetic fields known. WebThe detection of a faint, short gamma-ray burst (GRB 170817A) in coincidence with the gravitational wave (GW 170817) detection by LIGO/Virgo is at odds with the expected known luminosity and redshift distribution of short GRBs (sGRB). Examining the observer-frame parameter space of all Fermi-GBM sGRBs shows that the sGRB associated with …
