标题： A multi-wavelength analysis of a collection of short-duration GRBs observed between 2012-2015

摘要： 我们研究了短伽马射线暴（sGRB）130603B及其他在2012年至2015年期间由多个多波段设施观测到的八个sGRB事件的瞬时辐射和余辉特性，其中包括GTC 10.4米望远镜。这些事件的瞬时辐射高能数据由INTEGRAL/SPI/ACS、Swift/BAT和Fermi/GBM卫星获得。对于sGRB 130603B、sGRB 140606A、sGRB 140930B、sGRB 141212A和sGRB 151228A，在0.1-10 MeV能量范围内的INTEGRAL瞬时辐射数据未显示出扩展辐射或前兆活动的任何迹象，其光谱和时间特性与其它短暴类似。对于sGRB130603B，我们的新余辉测光数据约束了由于更密集的时间覆盖导致的预喷出时间衰减。对于sGRB 130603B，包含我们新的以及之前发表的测光数据的余辉光变曲线总体上与星际物质（ISM）余辉模型一致。使用LePHARE软件对sGRB 130603B和sGRB 141212A的宿主星系建模支持这样一个场景：即爆发环境正在进行适度的恒星形成活动。通过加入我们针对另外8个sGRB的晚期数据，我们能够对余辉、宿主星系或任何潜在千倍新星发射的未探测到的现象施加严格的限制。我们还讨论了sGRB 170817A/GW170817的晚期余辉观测，并与其他sGRB子集进行了比较。 显示英文摘要

摘要： We investigate the prompt emission and the afterglow properties of short duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015, observed by several multi-wavelength facilities including the GTC 10.4m telescope. Prompt emission high energy data of the events were obtained by INTEGRAL/SPI/ACS, Swift/BAT and Fermi/GBM satellites. The prompt emission data by INTEGRAL in the energy range of 0.1-10 MeV for sGRB 130603B, sGRB 140606A, sGRB 140930B, sGRB 141212A and sGRB 151228A do not show any signature of the extended emission or precursor activity and their spectral and temporal properties are similar to those seen in case of other short bursts. For sGRB130603B, our new afterglow photometric data constraints the pre jet-break temporal decay due to denser temporal coverage. For sGRB 130603B, the afterglow light curve, containing both our new as well as previously published photometric data is broadly consistent with the ISM afterglow model. Modeling of the host galaxies of sGRB 130603B and sGRB 141212A using the LePHARE software supports a scenario in which the environment of the burst is undergoing moderate star formation activity. From the inclusion of our late-time data for 8 other sGRBs we are able to; place tight constraints on the non-detection of the afterglow, host galaxy or any underlying kilonova emission. Our late-time afterglow observations of the sGRB 170817A/GW170817 are also discussed and compared with the sub-set of sGRBs.
