International Research Fellowship Program: Probing the Pulsar Emission Mechanism using Radio and X-ray Telescopes

[10734]洛曼：国际研究员奖励计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。该计划的奖励为联合研究提供了机会，并利用独特或互补的设施、专业知识和国外的实验条件。该奖项将为Andrea N. Lommen博士提供为期24个月的支持，让他与荷兰阿姆斯特丹大学的michel van der Klis博士一起进行研究。该项目由美国国家科学基金会数学和物理科学理事会多学科活动办公室提供资金。在这个项目中，Lommen博士将利用位于荷兰Dwingeloo的Westerbork合成射电望远镜（WSRT）的新功能，与阿姆斯特丹大学天文研究所的x射线专业知识一起开展三个新项目，研究脉冲星的发射机制。她将利用WSRT的同时多频能力，研究色散测量作为射电天文学中广泛使用的概念的有效性。其次，她将测量一组慢速脉冲星和毫秒脉冲星的非脉冲发射。第三，她将使用即将存档的XMM和钱德拉数据，结合WSRT的无线电定时数据来执行绝对定时，并获得一些x射线发射旋转动力脉冲星的相位分辨光谱。范德克里斯是脉冲星研究领域的主要权威之一。韦斯特博克是世界上最重要的射电望远镜设施之一

0107342LommenThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide twenty-four months of support to Dr. Andrea N. Lommen to do research with Dr. Michiel van der Klis at the University of Amsterdam in the Netherlands. Funding for this project is being provided by NSF's Math and Physical Sciences Directorate Office of Multidisciplinary Activities.For this project, Dr. Lommen will use the new capabilities of the Westerbork Synthesis Radio Telescope (WSRT) in Dwingeloo, the Netherlands, in conjunction with the x-ray expertise of the Astronomy Institute of the University of Amsterdam to undertake three new projects to study the emission mechanism in pulsars. She will study the validity of Dispersion Measure as a widely used concept in Radio Astronomy, using the simultaneous multi-frequency capability of WSRT. Second, she will measure off-pulse emission in a collection of slow and millisecond pulsars. Third, she will use soon-to-be archival XMM and Chandra data, in conjunction with radio timing data at WSRT to perform absolute timing, and acquire phase resolved spectra of a number of x-ray emitting rotation powered pulsars.Dr. van der Klis is one of the leading authorities in the field of pulsar research. Westerbork is one of the world's premier radio telescope facilities.***
