SPATIALLY RESOLVED PROPERTIES OF THE GRB 060505 HOST: IMPLICATIONS FOR THE NATURE OF THE PROGENITOR

摘要

GRB 060505 was the first well-observed nearby possible long-duration gamma-ray burst (GRB) that had no associated supernova. Here we present spatially resolved spectra of the host galaxy of GRB 060505, an Sbc spiral, at redshift z = 0.0889. The GRB occurr
