The association of long gamma-ray bursts with the deaths of m assive stars naturally suggests that the cosmic GRB rate should trace the star formation history. Finding ot herwise would provide important clues for the further development of our views concerning these rare, cur ious phenomena. Making use of a sample of 44 luminousSwift GRBs with redshifts in the range z = 0− 4, we find evidence of enhanced evolution in the GRB rate, with∼ 4 times as many GRBs being observed at z ≈ 4 than expected… CONTINUE READING
