This artist’s impression shows a kilonova produced by the collision of two neutron stars. By studying the consequences of a long gamma-ray burst (GRB), two independent teams of astronomers using a multitude of telescopes in space and on Earth, including the Gemini North Telescope in Hawai’i and the Gemini South Telescope in Chile, discovered the …

In the December 7 issue of the journal Nature, an international team of astrophysicists …
Enlarge / Artist’s impression of GRB 211211A. The kilonova and gamma burst is on the right. Aaron M. Geller/Northwestern/CIERA A year ago, astronomers discovered a powerful gamma-ray burst (GRB) lasting nearly two minutes, dubbed GRB 211211A. Now, this unusual event upends the long-held assumption that longer GRBs are the distinctive signature of a massive stellar …

Newswise – A team of astronomers led by Northwestern University has developed the most comprehensive inventory to date of the galaxies from which short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers identified the galactic foci of 84 SGRBs and probed the characteristics of 69 of the identified …

Artist’s impression of a gamma-ray burst powered by a neutron star. Credit: Nuria Jordana-Mitjans Gamma-ray bursts (GRBs) have been detected by satellites orbiting the Earth as bright flashes of the most energetic gamma radiation lasting milliseconds to hundreds of seconds. These catastrophic explosions occur in distant galaxies, billions of light-years from Earth. A subtype of …
