项目摘要

Dr. Stinebring and his Oberlin College undergraduate students will build on their previous discovery in pulsar timing spectra that a crisscross pattern that had been noticed for decades in dynamic spectra has a much clearer signature in transform space. This group has now studied this scintillation arc phenomenon extensively, using high dynamic range observations of pulsars obtained with large radio telescopes around the world. The research under this award will explore this phenomenon in detail using high-sensitivity observations from the Arecibo radio telescope and other large telescopes such as the National Radio Astronomy Observatory Green Bank Telescope. One goal of this work is to connect the detailed observations of scintillation arcs with the physical characteristics of turbulent gas in the ionized interstellar medium. The other goal is to use what is learned about scintillation details to correct for the effects of scattering on pulsar timing signals in order to assist in the detection of gravitational waves.This research will benefit the greater scientific community by advancing our knowledge about the Milky Way galaxy and by improving our chances of detecting gravitational waves. Both of these topics are of interest not only to specialists, but to a much wider audience as well. This research program will also involve undergraduate students. By working closely with Dr. Stinebring and his collaborators, the students will gain a broad range of technical skills as well as further develop their ability to independently explore scientific problems. The students will have the opportunity to use state-of-the-art electronics and computers at the largest radio telescopes in the world. Opportunities to collaborate with scientists in the U.S. and abroad and to report their work at conferences and in publications will enhance the student research experience and prepare them for graduate training or other roles in the technical workforce.
斯泰因布赖恩博士和他的奥伯林学院本科生将以他们之前在脉冲星计时光谱中的发现为基础,即在动态光谱中观察了几十年的交错模式在变换空间中的特征要清晰得多。这个小组现在已经利用世界各地的大型射电望远镜获得的脉冲星的高动态范围观测,对这种闪烁弧光现象进行了广泛的研究。该奖项下的研究将利用阿雷西博射电望远镜和其他大型望远镜(如国家射电天文台绿岸望远镜)的高灵敏度观测来详细探索这一现象。这项工作的一个目标是将闪烁弧的详细观测与星际电离介质中湍流气体的物理特性联系起来。另一个目标是利用所学到的关于闪烁细节的知识来修正散射对脉冲星定时信号的影响,以帮助探测引力波。这项研究将通过增进我们对银河系的了解和提高我们探测引力波的机会,使更多的科学界受益。这两个主题不仅对专家感兴趣,而且对更广泛的受众也很感兴趣。这项研究计划也将涉及本科生。通过与斯廷布林博士和他的合作者密切合作,学生们将获得广泛的技术技能,并进一步发展他们独立探索科学问题的能力。学生们将有机会在世界上最大的射电望远镜上使用最先进的电子设备和计算机。与美国和国外的科学家合作并在会议和出版物上报告他们的工作的机会将增强学生的研究经验,并为他们在研究生培训或技术劳动力中的其他角色做好准备。
