U.S.-France Cooperative Research: Particle Acceleration and Photon Emission in Supernova Remnants

0128883埃利森这个为期三年的奖项支持北卡罗来纳州立大学的唐纳德·C·埃里森和法国萨克雷核子研究中心天体物理系的安妮·德库谢尔在天文学方面的美法合作。他们建议研究超新星剩余物中非线性粒子加速和光子发射的自洽理论。其目的是提供一种准确和有效的手段来解释超新星遗迹和TeV伽马射线中的X射线和GeV伽马射线发射。这项研究利用了在包括美国钱德拉和欧洲XMM-牛顿任务在内的各种太空任务中收集的数据，以及从当前和未来的航天器任务和地面望远镜获得的数据。这位美国研究人员将激波加速和宇宙射线起源方面的专业知识带到了这次合作中。法国在超新星遗迹激波加热等离子体发射的X射线方面的专门知识和通过航天器飞行任务收集的数据方面的经验补充了这一点。这项合作将带来一种新的最先进的代码，将增进对宇宙射线冲击加速的理解，并影响其他天体物理学主题，如宇宙射线的起源、超新星遗迹的演化及其对星际介质的影响。该奖项代表美国方面向美国国家科学基金会和法国国家科学研究中心(CNRS)提出的平行建议。NSF将支付这名美国调查员的旅费和生活费。CNRS将支持法国研究人员访问美国。

0128883EllisonThis three-year award supports US-France collaboration in astronomy between Donald C. Ellison of North Carolina State University and Anne Decourchelle of the Astrophysics Department of the Center for Nuclear Studies in Saclay, France. They propose to study the self-consistent theory of nonlinear particle acceleration and photon emission in supernova remants. The objective is to provide an accurate and efficient means of interpreting X-ray and GeV gamma ray emissions in supernova remnants and TeV gamma rays. The research utilizes data collected during various space missions, including the US Chandra and European mission XMM-Newton, and data obtained from current and future spacecraft missions and ground-based telescopes. The US investigator brings to this collaboration on expertise in shock acceleration and cosmic ray origins. This is complemented by French expertise in X-rays from shock heated plasma emissions in supernova remnants and experience with data gathered through spacecraft missions. The collaboration will lead to a new state-of the art code that will advance understanding of the shock acceleration of cosmic rays and impact other astrophysics topics, such as, the origin of cosmic rays and the evolution of supernova remnants and their influence on interstellar medium.This award represents the US side of parallel proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigator. The CNRS will support visits by French researcher to the United States.
