Gravitational Radiation Sources for Cryogenic Resonant Bar Detectors

该职业奖将启动一个新的理论研究项目，研究与设计下一代声波引力波探测器相关的问题，这些探测器设计用于高频工作。将适当考虑探测器噪声的数据分析技术应用于截断等面体重力天线TIGA设计。这些技术将用于评估几个与天体物理相关的高频引力辐射源，包括但不限于双中子星或恒星质量黑洞系统合并产生的最终辐射爆发，超新星爆炸，进动脉冲星和一般非轴对称脉冲星。一项教育计划被提出，其重点是向非理科生传达科学探究的本质和进行科学探究的方式。这个项目的载体是一门天文学课程，满足大学的分配要求。计算机实验室将被建立起来，使学生能够通过检查星团内部恒星的分布来确定星团的年龄，或者校准距离尺度，找到哈勃常数和模型宇宙的年龄。此外，一个新的评估和研究工具-概念图-将被引入同一课程。一个概念是一个物体，如恒星、行星、星系、黑洞或一个事件，如日食、新星、恒星系年。新概念是根据它们与先前已知概念的关系来理解的。对已知概念的更深入理解对应于它们之间新关系的构建。概念图是学生已经认识到的概念和它们之间关系的图形表示。

This CAREER award will initiate a new theoretical research program to study issues connected with the design of the next generation of acoustic gravitational wave detectors designed to operate at high frequency. Data analysis techniques that properly account for detector noise will be adapted to the truncated isocahedral gravitational antenna TIGA design. These techniques will be used to evaluate several astrophysically relevant high-frequency gravitational radiation sources, including but not limited to the final burst of radiation from the coalescence of a binary neutron star or stellar mass black hole system, supernovae explosions, precessing pulsars, and general non axisymmetric pulsars. An educational program is proposed that focuses on communicating to non-science students the nature of scientific inquiry and the manner in which it is conducted. The vehicle for this program is an astronomy course that fulfills a university distribution requirement. Computer laboratories will be constructed that will allow students to, for example, determine the age of a star cluster by examining the distribution of stars within it, or calibrate the distance scale and find the Hubble constant and age of a model universe. In addition, a novel evaluation and study aid - concept maps - will be introduced into the same course. A concept is an object e.g., star, planet, galaxy, black hole or an event e.g., eclipse, nova, sidereal year . New concepts come to be understood in terms of their relationships with concepts previously known. Deeper understanding of concepts already known corresponds to the construction of new relationships between them. A concept map is a graphical representation of the concepts and the relationships among them that a student has come to recognize.
