4 giorni fa · Gamma rays come from black holes, neutron stars, supernovae (stars exploding at the end of their lives), pulsars, quasars, and other sources we don't understand yet. Great bursts of gamma rays occur frequently, and it's still a mystery where they are coming from.
3 giorni fa · The number of pulsars, or pulsating stars, discovered by China's FAST telescope has exceeded 800, scientists announced on Tuesday.
3 giorni fa · Fast radio bursts are bright, unresolved (pointsource-like), broadband (spanning a large range of radio frequencies), millisecond flashes found in parts of the sky. Unlike many radio sources, the signal from a burst is detected in a short period of time with enough strength to stand out from the noise floor.
1 giorno fa · pulsars may lead to overshooting the local positron flux measured with the AMS-02 experiment.Martin et al.(2022a) estimate that at most a fraction of 5-10% of nearby middle-aged pulsars could develop a gamma-ray halo. In total, in the Galaxy the upcoming Cherenkov Telescope Array is estimated to be able to detect
