This program includes research on a wide range of theoretical topics within the context of Gamma-ray Bursts (GRBs). The main objectives are to: (i) use GRBs as lighthouses of the high-redshift Universe, to probe the physical conditions of the Interstellar Medium in star-forming regions and their evolution with redshift; (ii) generalize previous dust echo calculations and use them to reconstruct the properties and distribution of dust around the massive stellar progenitors of GRBs; (iii) use the properties of short GRBs to learn about the various channels of binary star merger; (iv) perform a generalized study of ultra-relativistic shockwaves in arbitrary media; (v) study gravitational instabilities in the hyper-accreting disk believed to provide the GRB source of power.Broader impacts of the work include training of undergraduate and graduate students, and development of a planetarium show on GRBs at the Fiske Planetarium.

该计划包括在伽马射线暴（GRBs）背景下广泛的理论主题研究。主要目标是：(1)利用grb作为高红移宇宙的灯塔，探测恒星形成区域星际介质的物理条件及其随红移的演化；（ii）推广以往的尘埃回波计算，并利用它们重建grb大质量恒星祖先周围尘埃的性质和分布；（iii）利用短伽马射线暴的性质，了解双星合并的各种通道；（iv）对任意介质中的超相对论冲击波进行广义研究；(v)研究被认为提供GRB能量来源的超吸积盘的引力不稳定性。这项工作的更广泛影响包括对本科生和研究生的培训，以及在菲斯克天文馆举办关于grb的天文馆展览。
