WebJul 26, 2024 · On Aug. 26, 2024, NASA’s Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record books – the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen. WebJan 15, 2024 · Gamma ray bursts, intense explosions of light, are the brightest events ever observed in the universe – lasting no longer than seconds or minutes. Some are so luminous that they can be...
WebJan 1, 2024 · In addition to its educational aims, the mission is driven by several scientific and technological goals, including goals related to a novel gamma-ray instrument for the detection of bright transient astrophysical sources, such as gamma-ray bursts. This work provides a detailed description of the software development life-cycle for EIRSAT-1 ... WebIn these proceedings, we summarise the exploration so far of the relationship between the afterglow luminosity (measured at rest frame 200s; log L 200 s ) and average afterglow decay rate (measured from rest frame 200s onwards, α > 200 s ) of long duration Gamma-ray Bursts (GRBs), first reported in the optical/UV light curves of GRB afterglows. We …

By the standard definitions of "x-ray" and "gamma ray", any photon produced by bremsstrahlung is by definition an x-ray and not a gamma ray. However, there's no upper bound to the photon energy that can be produced by bremsstrahlung. That's the neat part, gamma rays are just x-rays from nuclear interactions. cultural diversity early childhood educationIn gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies. They are the most energetic and luminous electromagnetic events since the Big Bang. Bursts can last from ten milliseconds to several hours.
