A search for binary black hole candidates from the VLBI images of AGNs [PDF]
Xiang LiuWe have searched the core-jets pairs in the VLBI scales ($<$1 kpc), from several VLBI catalogues, and find out 5 possible binary black hole (BBH) candidates. We present the search result and analyze the candidates preliminarily, and further study with multi-band VLBI observation and optical line investigation would be carried out in the future.View original: http://arxiv.org/abs/1304.1955
