摘要

The ESA gamma-ray astronomy satellite INTEGRAL localized 46 gamma-ray bursts between October 2002 and July 2007. Spectral lags have been determined from the burst time profiles for about half the sample, despite the extreme faintness of many INTEGRAL bursts. INTEGRAL's sensitivity across the energy range of interest for the prompt burst emission allows us to investigate the hypothesis of a low-luminosity, nearby population of bursts. The azimuthal distribution of double-scatter events in SPI's germanium detectors, in conjunction with a sophisticated spacecraft and instrument mass model, have been used to place limits on the percentage of polarization in the prompt emission of the brightest INTEGRAL burst, GRB 041219a.
