摘要
Fermi卫星的GBM可以更精确地测量Epeak,以及LAT在GeV能段的定位和观测,提供了一个独特的研究伽玛暴谱能关系之一Eiso-Epeak关系的机会.根据9个具有红移的Fermi/LAT暴的谱能关系,发现长暴的这个关系满足一定的关系,而短暴却不满足.
The Fermi satellite, by exploiting the high accuracy of the GBM instrument in the measurement of Epeak , and the LAT instrument, by detecting and locating GRBs in the GeV energy range, provide a unique opportunity to investigate the Eiso-Epeak correlation. The Eiso-Epeak correlation of 9 GRBs with measured redshift indicates that long GRBs follow the correlation while short GRBs do not, which is consistent with previous findings.
