Il potente lampo di #raggigamma scoperto il #9ottobre 2022 è un evento estremamente raro, che si verifica una volta ogni diecimila anni. Le osservazioni, realizzate da #telescopi nello #spazio e a terra con forte coinvolgimento italiano, saranno determinanti per comprendere le colossali esplosioni da cui hanno origine i lampi gamma.

Astonishing. Gamma ray flash detected from the Tonga eruption, attributed to intense lightning in the plume

"We report a terrestrial gamma-ray flash (TGF) that was produced by the volcanic lightning and observed from space by the Fermi Gamma-ray Burst Monitor (GBM)"

Three articles published in the journal "Nature" and one article published in the journal "Nature Astronomy" report various aspects of the studies conducted on the out-of-normal gamma-ray burst cataloged as GRB 211211A. At that time, the gravitational wave detectors were not active but the event's characteristics indicate that the origin is in a kilonova, a merger between two neutron stars.
