- GRB_110328A abstract "Swift J1644+57 (also indicated as GRB 110328A when it was discovered) is the name of the event that occurred on March 28, 2011, the tidal disruption of a star by a supermassive black hole. It has been detected by the Swift Gamma-Ray Burst Mission on March 28, 2011. It occurred in the center of a small galaxy in the Draco constellation, about 3.8 billion light-years away.Studied by dozens of telescopes, it's one of the most puzzling cosmic blasts of high-energy radiation ever observed when it comes to brightness, variability and durability. It probably occurred when a star wandered too close to the central black hole in the galaxy, and was gravitationally torn apart and swallowed by it. Timing considerations suggest that the tidally disrupted star was a white dwarf and not a regular main sequence starDebris now encircles the black hole in an accretion disk,which launches bipolar jets at near thespeed of light.Jet plasma emits the γ- and X-rays.The beam of radiation from one of these jets points directly toward Earth,enhancing the apparent brightness.Repetitive dimming and softening of the X-raysimplies that the jet temporarily tilts away from us,due to precession of the warped disk.The jets drive shocksinto the surrounding interstellar medium,resulting in a radio to infraredafterglow.Detection of the relativistically expanding afterglowconfirmed the identity of the host galaxy.Observed linear polarizationof the infrared radiationis consistent with synchrotron emissionfrom the afterglow shock."This is truly different from any explosive event we have seen before," said Joshua Bloom of the University of California at Berkeley, the lead author of the study published in the June 2011 issue of Science.".
