摘要： (ProQuest: ... denotes formulae and/or non-USASCII text omitted) This study presents multi-wavelength observational results for energetic GRB 100414A with GeV photons. The prompt spectral fitting using Suzaku/WAM data yielded spectral peak energies of ... of ... keV and E sub(iso) of ... x 10 super(52) erg with z = 1.368. The optical afterglow light curves between 3 and 7 days were effectively fitted according to a simple power law with a temporal index of alpha = -2.6 + or - 0.1. The joint light curve with earlier Swift/UVOT observations yields a temporal break at 2.3 + or - 0.2 days. This was the first Fermi/LAT detected event that demonstrated the clear temporal break in the optical afterglow. The jet opening angle derived from this temporal break was 5[degrees].8, consistent with those of other well-observed long gamma-ray bursts (GRBs). The multi-wavelength analyses in this study showed that GRB 100414A follows ... and ... correlations. The late afterglow revealed a flatter evolution with significant excesses at 27.2 days. The most straightforward explanation for the excess is that GRB 100414A was accompanied by a contemporaneous supernova. The model light curve based on other GRB-SN events is marginally consistent with that of the observed light curve. 出版者： Bristol: IOP 出版日期： 2012-03-20 出處： Astrophysical journal.
