摘要: We report the Swift discovery of nearby long, soft gamma-ray burst GRB 100316D, and subsequent unveiling its low-redshift host galaxy associated supernova. derive redshift event to be z = 0.0591 +/- 0.0001 provide accurate astrometry for (GRB) supernova (SN). study extremely unusual prompt emission with time-resolved X-ray spectroscopy find that spectrum is best modelled a thermal component in addition synchrotron low peak energy. The light curve has remarkably shallow decay out at least 800 s. bright, blue highly disturbed morphology we use Gemini-South, Very Large Telescope Hubble Space observations measure some basic properties. compare contrast 100316D subsample GRB-SNe. unlike majority GRB-SNe evolution, but resembles rather 060218, these two events have similar high energy Comparison galaxies demonstrates, however, there great diversity environments which can found. an important currently sparse sample spectroscopically confirmed GRB-SNe, from better understanding long progenitors GRB-SN connection gleaned.
