Gamma Ray and Neutrino Observations of GRBs and choked GRBs

伽马射线暴（GRBs）是宇宙中最强大的事件之一。有了这个奖项，佐治亚理工学院的小组将使用HAWC和冰立方的数据来研究伽马射线暴的高能伽马射线和中微子发射。目前正在墨西哥建设的HAWC天文台对GRB发射的敏感度将比以前的地面仪器高一个数量级。该小组将在HAWC的设计和建造方面发挥重要作用，特别是在与grb研究有关的电子和软件方面。HAWC的数据可能会告诉我们由伽马射线暴加速的最高能量粒子，并可能揭示为伽马射线暴提供动力的相对论性喷流的细节。冰立方是一个在南极运行的高能中微子望远镜。该小组将使用DeepCore（冰立方的低能延伸）收集的数据来寻找瞬态中微子爆发。为了提高DeepCore的灵敏度，他们将采用一种新的、更宽松的否决技术来收集数据。他们将研究核心坍缩超新星（SNe）和grb之间的联系，以及许多核心坍缩超新星有隐藏或窒息喷流的假设。与核心坍缩超新星同时发现的中微子将证明它们和伽马射线暴都是连续天体物理物体的一部分。更广泛的影响：佐治亚理工学院小组将及时报告HAWC观测结果，使中微子（特别是冰立方/DeepCore）、引力波、x射线等多信使跟踪成为可能，从而扩大实验的科学范围。在与佐治亚理工学院CEISMC的合作下，PI和他的团队成员将继续他们在粒子、核物理和天体物理领域的讲座和实践演示项目。演示包括云室和盖革计数器等设备。这些高中的目标学生中有大量的西班牙裔学生，出生于拉丁美洲的PI与他们有着天然的联系。

Gamma Ray Bursts (GRBs) are among the most powerful events in the Universe. With this award the Georgia Tech group will use HAWC and IceCube data to study high-energy gamma ray and neutrino emission from GRBs. The HAWC observatory, currently under construction in Mexico, will be at an order of magnitude more sensitive to GRB emission than previous ground-based instruments. The group will play an important role in the design and construction of HAWC, particularly in the electronics and software related to the study of GRBs. The HAWC data may teach us about the highest energy particles accelerated by GRBs and may reveal details about the relativistic jets that power a GRB. IceCube is a high-energy neutrino telescope in operation at the South Pole. The group will use data collected by DeepCore, a low energy extension of IceCube, to search for transient bursts of neutrinos. To enhance DeepCore's sensitivity they will collect data with a new, looser vetoing technique. They will study the connection between core collapse supernovae (SNe) and GRBs and the hypothesis that many core collapse SNe have hidden or choked jets. The discovery of neutrinos in coincidence with core collapse SNe would prove that they and GRBs are part of continuous class of astrophysical objects. Broader Impact: The Georgia Tech group will report HAWC observations promptly to enable multi-messenger follow up with neutrinos (notably IceCube/DeepCore), gravitational waves, X-rays, etc., thus extending the scientific range of the experiments. In collaboration with CEISMC at Georgia Tech the PI and members of his group will continue their program of lectures and hands on demonstrations in the areas of particle and nuclear physics and astrophysics. Demonstrations include devices such as a cloud chamber and a Geiger counter. The high schools targeted have a large Hispanic population, for which the PI, born in Latin America, has a natural connection.
