Abstract

PBC J2333.9-2343 is a peculiar active nucleus with two giant radio lobes and a weak blazar-like nucleus at their centre. In this work we show new optical, ultraviolet (UV), and X-ray data taken from the San Pedro Martir telescope, the New Technology Telescope, NTT/EFOSC2, and the Swift/XRT satellite. The source is highly variable at all frequencies, in particular the strongest variations are found in the broad Ha component with a flux increase of 61 +/- 4 per cent between 2009 and 2016, following the X-ray flux increase of 62 +/- 6 per cent between 2010 and 2016. We also detected a broad H beta component in 2016, making the optical classification change from type 1.9 to type 1.8 in 1 yr. We have also detected a broad component of the [OIII]lambda 5007 line, which is blue-shifted and of high velocity, suggesting an origin from a highly disturbed medium, possibly an outflow. The line flux variability and broad widths are indicative of a jet that is, at least in part, responsible for the ionization of the broad line region (BLR) and narrow line region (NLR).
