gamma-ray burst

This work led to mission development and studies of gamma-ray bursts.

Over time it became clear that this was not a normal gamma-ray burst.

"A gamma-ray burst is the most mysterious thing about which we still have so little information."

"It doesn't fit in with anything that we had thought about gamma-ray bursts."

Some astronomers now think they have identified a new class of these gamma-ray bursts.

This is thought to be the precursor of a long gamma-ray burst.

Study gamma-ray bursts with an energy range several times more intense than ever before so that scientists may be able to understand them better.

This was the first evidence of a physical relationship between gamma-ray bursts and supernovae.

Gamma-ray bursts represent the most powerful known explosions in the universe.

Most observed events last longer than two seconds and are classified as long gamma-ray bursts.

It was the first direct evidence that at least some gamma-ray bursts come from supernovas.

Events with a duration of less than about two seconds are classified as short gamma-ray bursts.

The massive-star model probably does not explain all types of gamma-ray burst.

Usually, gamma-ray bursts mark the destruction of a massive star, and emissions from these events last no more than a few hours.

No such metallicity biases are known for short gamma-ray bursts.

Astronomers believe that this event is what creates certain kinds of gamma-ray bursts.

Second, there are now several observed cases where a supernova has immediately followed a gamma-ray burst.

In all that time, it showed no more gamma-ray bursts near enough to Earth to harm the biosphere.

This was the first X-ray halo that had ever been observed around a gamma-ray burst.

These observations provided strong evidence for a relation between gamma-ray bursts and supernova.

To determine the high-energy behavior of gamma-ray bursts and transients.

Gamma-ray bursts are very bright as observed from Earth despite their typically immense distances.

Gamma-ray burst in our part of the Milky Way.

Some 60 solar flares and 19 cosmic gamma-ray bursts were detected.

The primary function of the telescope is visual spectrum observation following Gamma-ray bursts.
