For the first time ever, scientists using the Atacama Large Millimeter/submillimeter Array have discovered molecular gas in galaxies that had once been rocked by gamma ray bursts, according to new research published Wednesday in the journal Nature.
Scientists had originally believed all gamma-ray bursts were followed by a radio afterglow, so Australian astronomers of the Centre for All-sky Astrophysics at Curtin University and the University of Sydney decided to set out to prove this theory.
ESAâ€™s Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein.
The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy.
Astronomers have for the first time measured the velocity of the explosions known as gamma-ray bursts. The material is travelling at the extraordinary speed of more than 99.999% of the velocity of light, the maximum speed limit in the Universe.
A time-series of high-resolution spectra in the optical and ultraviolet has twice been obtained just a few minutes after the detection of a gamma-ray bust explosion in a distant galaxy.
NASA's Swift satellite has challenged some of astronomers' fundamental ideas about gamma-ray bursts (GRBs), which are among the most extreme events in our universe.
Almost 40 years have passed since top secret nuclear weapon warning satellites accidentally discovered bursts of high energy gamma rays coming from space. Although many thousands of gamma ray bursts (GRBs) have since been detected, the origin and nature of these bursts is still not well understood.
NASA's Swift satellite and ground-based telescopes have discovered the most distant exploding star on record, confirming a 1999 prediction made by University of Chicago astrophysicist Don Lamb and Daniel Reichart, who was then a graduate student at Chicago.
A team of Italian astronomers said on Monday they had witnessed the afterglow from one of the brightest and most distant gamma-ray bursts ever detected.
