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-0507734Kulkarni伽马射线暴 (GRB) 是宇宙中最亮的爆炸，其亮度比超新星亮数百万倍，由高度相对论性的外流产生。 他们的研究直接和间接解决了天体物理学中一些最令人兴奋的问题，包括大质量恒星的死亡、黑洞和吸积物理学、宇宙粒子加速器以及中微子和引力波发射。 伽玛暴的极端亮度也使它们成为婴儿宇宙的理想探测器，用于系统研究宇宙老化过程中元素的生长。 该项目将继续大学和研究中心之间的合作，以利用地面设施获得对伽玛暴的重要观测，并通过综合理论努力继续开发物理诊断。加州理工学院的研究小组最近投入了大量精力，在帕洛玛 60 英寸望远镜上开发了机器人伽玛暴跟踪能力。 这项工作提供了一种培训学生仪器仪表并将他们融入研究的机制。 该项目还将包括通过帕洛玛游客中心和环绕该山的美洲原住民社区向代表性不足的群体进行宣传，并通过团队与媒体的持续参与向更广泛的社区进行宣传。
