Extragalactic Research at the Owens Valley Radio Observatory

活动星系将主要通过甚长基线干涉测量(VLBI)技术的高分辨率射电观测来研究。将对几个单独的物体进行详细研究，并对适用于统计分析的明确的物体样本进行研究。将完成使用VLBI技术的高分辨率射电观测、超大型阵列(VLA)的低分辨率射电观测以及Palomar 200英寸望远镜获取的光谱数据的大型项目。拟议中的观测应该会在各种“统一”的活动星系理论和相互竞争的超光速运动理论之间提供一个强有力的辨别。应该在未来三年内产生重要天体物理答案的具体问题将是这项研究的主要重点。计划中的科学计划的成功执行构成了理解活动星系的重要一步。为欧文斯河谷射电观测站40米望远镜的业务费用提供了部分支助。帕萨迪纳的加州理工学院减少了全球VLBI观测的数据，并在赠款中包括了对用于减少数据的相关器的运营成本的支持。这些设施是全球VLBI努力的基石。

Active galaxies will be studied primarily through high resolution radio observations by Very Long Baseline Interferometry (VLBI) techniques. Detailed studies of a few individual objects and studies of well-defined samples of objects, suitable for statistical analyses will be carried out. A large program of high resolution radio observations using VLBI techniques, lower resolution radio observations from the Very Large Array (VLA), and data on optical spectra taken on the Palomar 200-Inch Telescope will be done. The proposed observations should provide a powerful discriminant between various "unified" theories of active galaxies and between rival theories of superluminal motion. Specific problems that should yield astrophysically important answers within the next three years will be the main emphasis of the research. The successful execution of the planned scientific program constitute an important step toward understanding active galaxies. Partial support of the operations costs of the 40 meter telescope at the Owens Valley Radio Observatory are provided. The data from VLBI observations made around the earth are reduced at the California Institute of Technology in Pasadena and support for the operational cost of the correlator used to reduce the data is included in the grant These facilities are cornerstones of the world-wide VLBI effort.
