A search for binary black hole candidates from the VLBI images of AGNs
Abstract
We have searched the core-jets pairs in the VLBI scales (<1 kpc), from several VLBI catalogues, and find out 6 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.
