标题： Gamma Ray Bursts Spectral--Energy correlations: recent results

摘要： GRBs的EF_E谱的静止帧峰值Epeak与其各向同性能量(E_iso)或光度(L_iso)之间的相关性可能对理解GRB瞬时辐射有若干意义。这些相关性目前基于过去13年（预费米时代）由不同仪器收集的95个爆发样本的时间平均光谱特性，这些爆发具有测量的红移。一个尚未解决的问题是这些相关性是否具有物理起源，还是由于仪器选择效应。通过研究费米探测的10个长暴和14个短暴，我们发现E_peak与光度L_iso之间在单个GRBs内部存在强烈的时间分辨相关性，并且与时间积分相关性一致。这一结果直接证明了在短暴和长暴中存在类似的物理联系，将硬度与光度联系起来，这并非由于仪器选择效应。E_peak-L_iso相关性的起源应在于瞬时辐射的辐射机制。 显示英文摘要

摘要： The correlations between the rest frame peak of the EF_E spectrum of GRBs Epeak and their isotropic energy (E_iso) or luminosity (L_iso) could have several implications for the understanding of the GRB prompt emission. These correlations are presently founded on the time-averaged spectral properties of a sample of 95 bursts, with measured redshifts, collected by different instruments in the last 13 years (pre-Fermi). One still open issue is wether these correlations have a physical origin or are due to instrumental selection effects. By studying 10 long and 14 short GRBs detected by Fermi we find that a strong time-resolved correlation between E_peak and the luminosity L_iso is present within individual GRBs and that it is consistent with the time-integrated correlation. This result is a direct proof of the existence in both short and long GRBs of a similar physical link between the hardness and the luminosity which is not due to instrumental selection effects. The origin of the E_peak-L_iso correlation should be searched in the radiation mechanism of the prompt emission.
