GRB 070714B was a
radio
).
At a total duration of only 3 seconds, GRB 070714B was classified as a short burst, a subclass of GRBs which is believed to be caused by the merger of two
light years
, making it the most distant short burst detected as of 2007.
Observations
GRB 070714B was detected by the
UTC. The burst lasted only 3 seconds and reached its peak intensity 0.2 seconds after the initial detection.[1] The optical afterglow was detected by the Liverpool Telescope[2] and the William Herschel Telescope.[3]
Distance record
Spectroscopy of the optical afterglow and the burst's host galaxy revealed a single emission line of
orders of magnitude higher than short-duration bursts with a redshift less than z = 0.5, but still significantly smaller than typical long-duration bursts.[7]
