Web20 de nov. de 2024 · For H.E.S.S. (High Energy Stereoscopic System), this location became visible only 10 hours later. Nevertheless, the H.E.S.S. team decided to search for a very-high-energy afterglow of the burst. After having looked for a very-high-energy signature of these events for more than a decade, the efforts by the collaboration now …
Big star energy: record-breaking explosion recorded
Web27 de fev. de 2024 · Here, we will search for emission which may occur after the prompt GRB event; temporally extended high-energy emission has been detected in a large number of LAT bursts. We rerun gtselect on a time interval of ~40 to 400 seconds after the trigger on the file downloaded from the archive and renamed "FT1.fits", choosing to … Web16 de out. de 2024 · The X-ray telescope from NASA's Neil Gehrels Swift Observatory captures the afterglow of GRB 221009A about an hour after it was first detected. The bright rings form as a result of X-rays scattered from otherwise unobservable dust layers within our galaxy that lie in the direction of the burst. /NASA biotech hanse
Chinese astronomers detect record-breaking gamma-ray burst
Web13 de jun. de 2024 · For 10 years, NASA’s Fermi Gamma-ray Space Telescope has scanned the sky for gamma-ray bursts (GRBs), the universe’s most luminous explosions. A new catalog of the highest-energy blasts provides scientists with fresh insights into how they work. “Each burst is in some way unique,” said Magnus Axelsson, an astrophysicist at … Web28 de out. de 2024 · Searching for X-ray and gamma-ray bursts, including Gamma-ray bursts (GRBs), Soft Gamma-ray Repeaters (SGRs), and high energy transients … Web10 de set. de 2024 · At the pre-burst stage of neutrinos, high-energy neutrinos can interact with the matters of the GRB source at the edge, so these neutrino events can be accompanied by some high-energy photon events in the source reference frame.
