Extragalactic Radio Source Studies

这个项目是B.F. Burke博士领导的研究小组的开创性工作的延续，他们专注于引力透镜的研究。他们对南半球的大规模调查正在进行中，预计会发现更多有趣的天体。一旦确定，这些系统将利用引力时间延迟效应获得哈勃常数的独立评估。那些新发现的爱因斯坦环型也将使银河系质量的确定成为可能。此外，该小组将利用调查材料寻找高红移射电星系和类星体，并研究它们的射电特性。

This program is a continuation of the pioneering work of the group headed by Dr. B.F. Burke, concentrating on the study of gravitational lenses. Extension of their large survey to the Southern hemisphere is under way, and the discovery of more of these interesting objects is anticipated. Once identified, these systems will be utilized to obtain an independent evaluation of the Hubble constant, using the gravitational time delay effect. Those of the newly discovered Einstein ring type will also allow definitive determinations of galactic masses. In addition, the group will use the survey material to search for high-redshift radio galaxies and quasars, and to study their radio properties.
