All Jets Great and Small: Understanding the Role of Outflows in the Broadband Spectra of XRBs and LLAGN

ast - 0201597 -马尔柯夫,SeraDr。Markoff被授予美国国家科学基金会天文学和天体物理学博士后奖学金，在麻省理工学院空间研究中心开展研究和教育项目。她将对天体物理喷流进行理论和观测研究，这是在吸积黑洞视界附近形成和排出的相对论性等离子体的双喷流。她将开发模型来预测喷流对恒星x射线双星和低亮度活动星系核的宽带光谱的贡献，它们在质量上相差几个数量级，但在比例功率上接近。她参与的观测活动将为验证这些预测以及驱动恒星和星系规模喷流的引擎之间潜在的相似性提供数据。她的研究计划将解决有关喷气机的基本问题，如它们的形成和物质含量。她将把她的研究纳入一个新的教育单元，用于参与“天文计划”的教室，并为波士顿科学博物馆、当代科学技术中心举办展览。她还计划在博物馆和当地教师的专业发展研讨会上教授相关课程

AST-0201597Markoff, SeraDr. Markoff is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at MIT's Center for Space Research. She will conduct a theoretical and observational study of astrophysical jets, twin outflows of relativistic plasma formed and expelled near the event horizons of accreting black holes. She will develop models for predicting the contribution of jets to the broadband spectra of stellar X-ray binaries and low-luminosity active galactic nuclei, which are orders of magnitude apart in mass, but close in scaled power. Her participation in observational campaigns will provide data for testing these predictions and the underlying similarities between the engines that drive jets of stellar and galactic scale. Her program of research will address fundamental outstanding questions pertaining to jets, such as their formation and matter content. She will incorporate her research into a new educational unit for classrooms participating in Project Astro and for an exhibit for the Boston Museum of Science, Current Science and Technology Center. She also plans to teach associated courses at the Museum and at local teachers' professional development workshops.***
