This award supports a well-integrated program of research and teaching in computational physics at Bowdoin College, a highly selective undergraduate institution located in Brunswick, Maine. The awarded funds will provide support for research in numerical relativity and computational astrophysics and for undergraduate students to participate in this research. The research goals, involving supercomputer simulations of neutron stars and black holes, are primarily motivated by the prospect of detecting gravitational radiation from such objects with the new generation of gravitational wave laser interferometers, including the now operational Laser Interferometer Gravitational wave Observatory (LIGO.) To identify and interpret any observed signals, and to extract their astrophysical content, requires theoretical models of their sources. Likely sources such as binary neutron stars and black holes must be modeled within the framework of general relativity. This research is aimed at developing the necessary numerical algorithms, at numerically constructing such theoretical models, and at predicting gravitational wave signals for comparison with future observation. Undergraduate students will actively participate in a computational physics research group, providing them with a "hands-on" research experience and generating a research-enriched learning environment. The students will work on a variety of well-defined, manageable and meaningful projects, including, for example, the generalization and extension of previous results and the exploration of simple model problems. They will also have the opportunity to collaborate with scientists at other institutions and to present their work at conferences and in publications, making this research experience a very valuable preparation for graduate training and other future careers in the sciences and beyond.

该奖项支持鲍登学院（Bowdoin College）的计算理学研究与教学计划，该计划位于缅因州的一家高度选择性的本科机构。奖励的资金将为数值相对性和计算天体物理学的研究提供支持，并让本科生参与这项研究。涉及中子恒星和黑洞的超级计算机模拟的研究目标主要是由新一代重力波激光干涉仪检测到从此类物体中检测重力辐射的前景，包括现在的操作激光干涉仪干涉仪重力计重力测测值（LIGO），以识别和解释任何观察的信号。必须在一般相对论的框架内建模诸如二进制中子星和黑洞之类的可能来源。这项研究旨在开发必要的数值算法，旨在通过数值构建此类理论模型，并预测引力波信号，以与将来的观察结果进行比较。本科生将积极参加计算物理研究小组，为他们提供“动手”研究经验并产生富含研究的学习环境。学生将研究各种定义明确，易于管理和有意义的项目，例如，包括先前结果的概括和扩展以及简单模型问题的探索。他们还将有机会与其他机构的科学家合作，并在会议和出版物中介绍他们的工作，使这项研究经历成为研究生培训和科学及其他未来职业的非常宝贵的准备。
