The ‘Brightest of All Time’ Gamma-Ray Burst and Its Ordinary Supernova

A team of astronomers using the Gemini South telescope, one half of the International Gemini Observatory operated by NSF’s NOIRLab, have observed the ‘brightest of all time’ long gamma-ray burst. Using the Gemini South Multi-Object Spectrograph (GMOS), the team found that although GRB 221009A exhibits a jet structure as rare as it is bright, its associated supernova is surprisingly ordinary.

La explosión de rayos gamma “más brillante de todos los tiempos”

Un equipo de astrónomos observó la explosión de rayos gamma “más brillante de todos los tiempos” con el telescopio Gemini Sur, la mitad austral del Observatorio Internacional Gemini que opera NOIRLab de NSF. Gracias al Espectrógrafo Multi Objetos de Gemini Sur (GMOS por sus siglas en inglés), el equipo descubrió que, a pesar que GRB 221009A presentaba una estructura de jet tan inusual como su brillo, su supernova no era nada fuera de lo común.

Deep-Space Discovery: Oddball Gamma-Ray Burst Forces Revision of Theoretical Framework

In the Dec. 7 issue of the journal Nature, an international team of astrophysicists report the discovery of a unique cosmological gamma-ray burst (GRB) that defies prevailing theories of how the violent cosmic explosions form.

Record-Breaking Gamma-Ray Burst Possibly Most Powerful Explosion Ever Recorded

In the early-morning hours of today, 14 October 2022, astronomers using the Gemini South telescope in Chile operated by NSF’s NOIRLab observed the unprecedented aftermath of one of the most powerful explosions ever recorded, Gamma-Ray Burst GRB221009A. This record-shattering event, which was first detected on 9 October 2022 by orbiting X-ray and gamma-ray telescopes, occurred 2.4 billion light-years from Earth and was likely triggered by a supernova explosion giving birth to a black hole.
