This award supports a program of research and education in computational physics at Bowdoin College, a highly selective undergraduate institution located in Brunswick, Maine. The supported research, in the areas of gravitational wave source simulations (numerical relativity) and computational astrophysics, provides opportunities for undergraduate students to participate. The research goals, involving numerical simulations of neutron stars and black holes in binary orbit, are primarily motivated by the prospect of detecting gravitational radiation from such objects with the new generation of gravitational wave laser interferometers, including the Laser Interferometer Gravitational wave Observatory (LIGO.) To identify and interpret any observed signals, and to extract their astrophysical content, requires theoretical models of the sources. The extreme environments of neutron stars and black holes require them to be modeled within the framework of Einstein's theory of general relativity. The research activities supported by this award are aimed at developing the necessary numerical algorithms, at numerically constructing such theoretical models, at predicting gravitational wave signals for comparison with future observation, and at answering related astrophysical questions.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Bowdoin College的计算物理研究和教育计划，Bowdoin College是位于缅因州不伦瑞克省的高度选择性的本科机构。在引力波源模拟（数值相对性）和计算天体物理学领域的支持研究为本科生提供了机会。涉及中子星和二进制轨道中的黑洞的数值模拟的研究目标主要是由于检测来自此类物体的重力辐射的前景，新一代引力波激光干涉仪，包括激光干涉仪的重力计重力测量值（LIGO），要求识别和解释其模型。中子星和黑洞的极端环境要求它们在爱因斯坦的一般相对论框架内建模。该奖项支持的研究活动旨在开发必要的数值算法，即在数值上构建这种理论模型，旨在预测引力波信号，以与未来的量化进行比较，并在回答相关的天体物理问题上。不毕业的学生将积极参与计算物理学研究小组，并为他们提供操作？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。
