我们与韩国 VLBI 网络 (KVN) 启动了两个观测计划，在 22、43、86、129 GHz 下同时监测伽马射线明亮活动星系核中相对论性喷流的通量密度和偏振变化。其中之一是从 2011 年 5 月开始使用 KVN 21 米直径射电望远镜进行的双偏振单碟每周观测计划。另一个是从 2012 年 12 月开始的 VLBI 月度观测计划，采用三元 VLBI 网络，角分辨率范围为 1.0-9.2 mas。监测观测的目的是研究伽马射线的变化与射电通量密度和相对论性喷流爆发时的偏振的相关性。这些观测使我们能够研究活动星系核伽马射线耀斑的起源。
We started two observing programs with the Korean VLBI Network (KVN) monitoring changes in the flux density and polarization of relativistic jets in gamma-ray bright AGNs simultaneously at 22, 43, 86, 129 GHz. One is a single-dish weekly-observing program in dual polarization with KVN 21-m diameter radio telescopes beginning in 2011 May. The other is a VLBI monthly-observing program with the three-element VLBI network at an angular resolution range of 1.0-9.2 mas beginning in 2012 December. The monitoring observations aim to study correlation of variability in gamma-ray with that in radio flux density and polarization of relativistic jets when they flare up. These observations enable us to study the origin of the gamma-ray flares of AGNs.
