After Black Holes Collide, a Puzzling Flash
A surprising flash that accompanied a black hole collision is leading physicists to rethink what black holes can do.
What Do You Get When Two Neutron Stars Merge?
What remnant is formed by a neutron-star merger: another neutron star? Or a black hole? The answer determines whether or not an explosion of energy is released in the form of a gamma-ray burst. The me...
Lawrence Livermore Scientists Move One Step Closer To Mimicking Gamma-Ray Bursts
Using ever more energetic lasers, Lawrence Livermore researchers have produced a record high number of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes,...
Brightest Explosion In the Universe Ever Seen Defies Astronomy Theories
When a colossal blast of light was detected near the constellation Leo earlier this year, astronomers were mystified about the origin of the violent explosion. Now, new research confirms the event was...
History of gamma-ray burst research
The history of gamma-ray burst research began with the serendipitous detection of a gamma-ray burst (GRB) on July 2, 1967 by the U.S. Vela satellites. After these satellites detected fifteen other GRB...

Gamma-ray burst progenitors
Gamma-ray burst progenitors are the types of celestial objects that can emit gamma-ray bursts (GRBs). GRBs show an extraordinary degree of diversity. They can last anywhere from a fraction of a secon...
