MeerKAT Radio Observations of ESO 137-006

MeerKAT radio telescope visibility data for the radio galaxy ESO 137-006, located in the Norma galaxy cluster (Abell 3627) at a distance of approximately 70 megaparsecs. The observations cover two frequency bands (980–1080 MHz and 1356–1440 MHz) and comprise 14 hours of on-target integration time taken in May 2019 using all 64 MeerKAT antennas. These data led to the discovery of multiple collimated synchrotron threads (CSTs) — narrow, thread-like structures of radio emission connecting the galaxy's radio lobes — a configuration not previously observed in radio galaxies (Ramatsoku et al. 20...本数据集为射电星系ESO 137-006的MeerKAT射电望远镜可见度数据，该星系位于矩尺座星系团（阿贝尔3627，Abell 3627），距离约70百万秒差距。本次观测覆盖两个频段（980–1080 MHz与1356–1440 MHz），包含14小时的目标源积分时长，于2019年5月使用全部64台MeerKAT天线完成。依托该数据集，研究人员发现了多组准直同步辐射丝（collimated synchrotron threads，CSTs）——即连接该星系射电瓣的窄丝状射电辐射结构——这类构型此前从未在射电星系中被观测到（Ramatsoku等人，20...）
