«Gamma - ray bursts are catastrophic events, related to the explosion of massive stars 50 times the size of our sun.
This image shows the most common type of gamma - ray burst, thought to occur when a massive star collapses, forms a black hole, and blasts particle jets outward at nearly the speed of light.
Long gamma - ray bursts, which flash for up to 100 seconds or longer, are believed to occur when massive stars explode as supernovae.
Most astrophysicists think that gamma ray bursts, fantastically energetic flares from deep space, stream from new black holes that form when the cores of massive spinning stars collapse to trigger supernovas.
«Many astronomers, including our group, have already provided a great deal of evidence that long - duration gamma - ray bursts (those lasting more than two seconds) are produced by the collapse of extremely massive stars.
Extremely bright exploding stars, called superluminous supernovae, and long gamma ray bursts also occur in this type of galaxy, he noted, and both are hypothesized to be associated with massive, highly magnetic and rapidly rotating neutron stars called magnetars.
Gamma rays usually follow the death of a massive star but these bursts were 88,000 light - years from the nearest galaxy.
The team used the Faint Object Camera and Spectrograph (FOCAS) mounted on the Subaru Telescope to thoroughly study the visible wavelength spectrum (Note 1) of the afterglow of a gamma - ray burst (GRB, Note 2), which is a violent explosion of a massive star.
Type Ic supernovae, the explosions after the core collapse of massive stars that have previously lost their hydrogen and helium envelopes, are particularly interesting because of their link with long - duration gamma ray bursts.
The intense radiation was part of a gamma - ray burst that lasted a minute and which marked the death of a massive star transmogrifying itself into a black hole.
That's the conclusion of a group of physicists who studied the effects of massive cosmic explosions, called gamma ray bursts, on planets.
Ray Jayawardhana: It is a clue that most likely, these high energy neutrinos come either from jets of particles that are accelerated by super massive black holes at the hearts of galaxies, or from really gigantic stars that explode at the end of their lives that also produce a phenomenon we call gamma ray bursts, which also might accelerate particles to very high speeds and energies.
Most gamma - ray bursts are believed to signal the violent death of rapidly spinning, massive stars.
The new observations support the theory that gamma - ray bursts result from the explosion of massive stars known as hypernovae.
Gamma ray bursts appear as a directional burst of energy from collapsed massive stars.
Similar results have been found for bursts of gamma rays associated with the explosion of massive stars.
In this artist's rendering, jets of high - energy radiation shoot out from a Gamma - ray burst, signaling the death of a massive star.
So, in theory, any gamma ray bursts coming from colliding dark matter particles — the Weakly Interacting Massive particles (WIMPs)-- should be clearly visible.
