Sub-parsec-scale Accleration of the Radio Jet in the Powerful Radio Galaxy NGC 6251
arXiv:astro-ph/0008173 · doi:10.1093/pasj/52.6.989
Abstract
In order to investigate the genesis of powerful radio jet, we have mapped the central 10 pc region of the nearby radio galaxy NGC 6251 with a 0.2 pc resolution using Very Long Baseline Interferometer (VLBI) at two radio frequencies, 5 GHz and 15 GHz, we have found the sub-parsec-scale counterjet for the first time in this radio galaxy. This discovery allows us to investigate the jet acceleration based on the relativistic beaming model.
