Noun
GRB (plural GRBs)
(astronomy) Initialism of gamma-ray burst.
A few percent of the Type Ic supernovae are associated with gamma-ray bursts (GRB), though it is also believed that any hydrogen-stripped Type Ib or Ic supernova could produce a GRB, depending on the geometry of the explosion. Source: Internet
An average long GRB has a bolometric flux comparable to a bright star of our galaxy despite a distance of billions of light years (compared to a few tens of light years for most visible stars). Source: Internet
An optical transient event associated with this GRB has not been found, despite its intensity. Source: Internet
A remarkable long-duration gamma-ray burst was GRB 050525A, which flared in 2005. Source: Internet
Assuming the gamma-ray explosion to be spherical, the energy output of GRB 080319B would be within a factor of two of the rest-mass energy of the Sun (the energy which would be released were the Sun to be converted entirely into radiation). Source: Internet
Content studio and global distribution company GRB Studios has acquired two original unscripted series for international distribution. Source: Internet
