摘要
我们研究了短时长伽马射线暴（sGRB）130603B 以及 2012-2015 年间另外八个 sGRB 事件的瞬时辐射与余辉性质，这些事件由包括 GTC 10.4m 望远镜在内的多个多波段设备观测。事件的瞬时辐射高能数据由 INTEGRAL/SPI/ACS、Swift/BAT 和 Fermi/GBM 卫星获得。sGRB 130603B、sGRB 140606A、sGRB 140930B、sGRB 141212A 和 sGRB 151228A 的 INTEGRAL 在 0.1-10 MeV 能量范围内的瞬时辐射数据未显示任何延展辐射或前驱活动的迹象，且其光谱与时间性质与其他短暴中所见相似。对于 sGRB130603B，我们新的余辉测光数据由于更密集的时间覆盖而约束了喷流断裂前的临时衰减。对于 sGRB 130603B，包含我们新数据及先前已发表测光数据的余辉光变曲线与 ISM 余辉模型大体一致。使用 LePHARE 软件对 sGRB 130603B 和 sGRB 141212A 的宿主星系进行建模支持这样一种情形：暴的环境正经历中等程度的恒星形成活动。通过纳入我们对另外 8 个 sGRB 的晚期数据，我们能够对其余辉、宿主星系或任何潜在千新星辐射的未探测施加严格约束。我们还讨论并比较了 sGRB 170817A/GW170817 的晚期余辉观测与这一 sGRB 子集。
