AST-0507734KulkarniGamma-ray bursts (GRBs), the brightest explosions in the Universe, shine millions of times brighter than supernovae, and are produced by highly relativistic outflows. Their study directly and indirectly addresses some of the most exciting questions in astrophysics, including the deaths of massive stars, black hole and accretion physics, cosmic particle accelerators, and neutrino and gravitational wave emission. The extreme brightness of GRBs also makes them ideal probes of the infant Universe, for systematic studies of the growth of elements as the Universe aged. This project will continue a collaboration between a university and a research center to obtain crucial enabling observations of GRBs using ground-based facilities, along with an integrated theory effort to continue development of physical diagnostics.The Caltech group has recently expended significant effort developing a robotic GRB follow-up capability at the Palomar 60-inch telescope. This effort provides a mechanism to train students in instrumentation, and to integrate them into the research. The project will also include outreach to under-represented groups, through the Palomar visitor center and the Native American communities that ring that mountain, and to a wider community through continuing involvement of the team with the media.

AST-0507734Kulkarnigamma-ray爆发（GRB），宇宙中最亮的爆炸，闪耀比超新星更亮了数百万倍，并且由高度相对论的流出产生。 他们的研究直接和间接地解决了天体物理学中一些最令人兴奋的问题，包括大恒星，黑洞和增生物理学的死亡，宇宙粒子加速器以及中微子和重力波发射。 GRB的极端亮度也使它们成为婴儿宇宙的理想探针，用于系统地研究元素的增长。 该项目将继续在大学与研究中心之间进行合作，以获得基于地面设施的GRB观察，以及综合理论的努力，以继续开发物理诊断。 这项工作提供了一种机制，可以培训学生进行仪器，并将他们整合到研究中。 该项目还将包括通过帕洛马尔游客中心和敲响那座山的美洲原住民社区的代表性不足的团体以及通过媒体的持续参与而向更广泛的社区进行宣传。
