The Radio-Fermi Connection: A Critical Study of Relativistic Jets

该项目的目标是继续一个非常成功的项目，即在欧文斯谷射电天文台的40米射电望远镜上监测blazars和射电星系的15ghz通量密度。耀变体是高度发光和高度活跃的射电、光学、x射线和&amp；#947；-射线辐射由星系核中的大质量黑洞提供能量。通过与同步&amp；#947；该项目将有助于阐明这些天体的发射机制、能量来源和射流准直过程。特别是无线电和&amp；#947；射线耀斑可以确定辐射源的位置，并确定它们是否与黑洞周围的喷流或吸积盘有关。这项工作更广泛的影响包括培养本科生和研究生。获奖者将与喷气推进实验室的同事、戈德斯通苹果谷射电望远镜和刘易斯教育研究中心合作，继续他们的教育推广计划，将美国和国际学校的教师带到加州，通过亲身体验射电望远镜，学习天文学和现代科学方法。这些教师将把他们的知识和工具带回学校，并将其应用到高中教学项目中。

The goal of this project is to continue a very successful program of monitoring the 15 GHz flux densities of blazars and radio galaxies on the 40m radio telescope at the Owens Valley Radio Observatory. Blazars are highly luminous and highly active sources of radio, optical, x-ray, and γ-ray radiation powered by massive black holes in galactic nuclei. By comparing the radio light curves with simultaneous γ-ray light curves from NASA's Fermi Gamma-Ray Space Telescope the project will help to elucidate the emission mechanisms, energy sources, and jet collimation processes in these objects. In particular, measurement of time-delays between radio and γ-ray flares can tie down the location of the radiation sources and determine whether they are associated with the jets or accretion disks around the black holes.Broader impacts of the work include training of undergraduate and graduate students. The awardees will continue their educational outreach program in collaboration with colleagues at the Jet Propulsion Laboratory and with the Goldstone Apple Valley Radio Telescope and the Lewis Center for Educational Research to bring teachers from US and international schools to California to learn astronomy and modern scientific methods via hands-on experience with radio telescopes. The teachers will take their knowledge and tools back to their schools and apply them in high-school teaching programs.
