Salmaso Padova-Asiago AGN 0.095 1 Add Padova-Asiago AT2019lrq is a type 1 AGN at z = 0.095, as measured by the low ionization line [O II] 3727. The high ionization lines of [O III] are shifted with respect to the galaxy restframe by more than 100 km/s, suggesting a disturbed kinematics of the gas. A similar behavior is present in the Balmer lines. In particular, the Hbeta likely has three distinct kinematic components. The first has a FWHM of 1850 km/s and is blueshifted by 1680 km/s. The second component is in the same rame as the [O II] line, and has a FWHM of 1050 km/s. The last one, instead, is redshifted by 1360 km/s, and it has a FWHM of 2100 km/s. This behavior is reminiscent of a candidate black hole binary (Bon et al. 2012, 2016). The optical image, indeed, shows possible signs of a recent merger, which could account for these peculiar properties. 2019TNSCR1333....1T
