U.S.-Korea Cooperative Science: Network for Optical Detection of Gamma-Ray Bursts

9910484公园该提案支持利弗莫尔劳伦斯·利弗莫尔国家实验室的朴惠洙博士和韩国延世大学的Yong-ik Byun博士之间为期两年的合作研究。这项拟议中的合作旨在通过在加利福尼亚州、亚利桑那州、美国和韩国三个地质地点之间形成一个望远镜网络来研究伽马射线暴的即时光学信号。PI还建议通过分析来自这些望远镜的数据来研究可变的天文物体。在过去的几年里，利弗莫尔实验室的朴惠洙博士领导了一个名为LOTIS的小组，用来对伽玛暴进行光学探测。PI现在正在准备一台60厘米的宽视场望远镜，以便在基特峰进行更有力的观测。延世大学的Yong-Ik Byun教授一直在准备两台名为TSTAR的50厘米宽视野望远镜，将于今年秋天在韩国安装并投入使用。私人投资机构建议将美国和韩国的这两项独立努力结合起来。通过拟议的合作，YSTAR望远镜将有能力通过绕轨道伽马射线爆发探测器在首次探测到伽马射线暴后20秒内跟踪伽马射线暴事件。韩国和美国的地理位置使联合小组能够连续监测大片天空，而不会有明显的中断。YSTAR的高速计算设施还将分析LOTIS数据档案中的其他光学瞬变事件。该项目将在美韩合作科学计划下与韩国的Byun博士团队一起执行。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。

9910484ParkThis proposal supports a 2-year collaborative research between Dr. Hye-Sook Park, Lawrence Livermore National Laboratory, Livermore and Dr. Yong-Ik Byun, Yonsei University, Korea. The proposed collaboration aims to study the prompt optical signal from gamma ray bursts by forming a telescope network between 3 geological sites: California, Arizona, U.S.A. and South Korea. The PIs also propose to study variable astronomical objects by analyzing data from these telescopes. Dr. Hye-Sook Park at Livermore Lab has led a group called LOTIS for optical detection of GRBs during the past few years. The PI is now preparing a 60cm wide-field telescope for more vigorous observations at Kitt Peak. Professor Yong-Ik Byun at Yonsei University has been preparing two 50cm wide-field survey telescopes called TSTAR, which will be installed and become operational this fall in Korea. The PIs propose to combine these two separate efforts in the U.S. and Korea. By the proposed collaboration, YSTAR telescopes will have capability to follow-up GRB events within 20 seconds after the initial detection by orbiting gamma-ray burst detectors. The geographical locations of Korea and U.S. allow the joint team to monitor large areas of the sky continuously without significant interruption. YSTAR's high speed computing facility will also analyze the LOTIS data archive for other optical transient events.This project will be performed in conjunction with Dr. Byun's group at Korea under the U.S.-Korea Cooperative Science Program. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program, which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
