Web4 de dez. de 2024 · Researchers say the gamma ray burst unleashed more energy in a blink of an eye than the Sun will produce over its entire 10-billion-year lifetime. Short gamma ray bursts are among the most energetic, explosive events known in the cosmic universe, second only to the Big Bang itself. Usually lasting for less than two seconds, these … Web13 de jul. de 2024 · Soft gamma ray bursts from magnetars are thought to involve starquakes, perhaps triggered by interactions between the neutron star’s crust and its intense magnetic field. Magnetars rotate once every few seconds, and if the rotation is accompanied by a precession — a wobble in the rotation — that might make the source …
Web17 de out. de 2024 · Gamma-ray bursts, or GRBs, are the most powerful class of explosions in the universe, according to NASA. Scientists have dubbed this one GRB 221009A, and … Several models for the origin of gamma-ray bursts postulated that the initial burst of gamma rays should be followed by afterglow: slowly fading emission at longer wavelengths created by collisions between the burst ejecta and interstellar gas. Early searches for this afterglow were unsuccessful, largely because it is … Ver mais In gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies.
