Environment around gamma ray bursts

11 June, 2014 / Read time: 1 minute

Simulation of the environment around GRB 020819B based on new observations with the Atacama Large Millimeter/submillimeter Array (ALMA). Gamma-ray bursts (GRBs) are intense bursts of extremely high energy observed in distant galaxies, the brightest explosive phenomenon in the Universe.

The GRB observed by ALMA, occurred in an arm of a galaxy in the constellation of Pisces, and the data revealed that GRB 020819B is likely to have been generated in an environment surrounded by dust-rich star-forming regions, where many new stars are born.
