Examples of type 1 AGN hosts with tidal features, which have log(L_[O III]/erg s⁻¹) > 41.4. First row: Color images from SDSS. The galaxy ID is provided. The horizontal bar indicates the angular scale of the image. Second row: r-band deep images of the DESI Legacy Imaging Survey. The angular scale of the deep image matches that of the color image in the first row. Third row: Optical spectra of type 1 AGNs covering the observed wavelength range 4700–7400Å, in which Hβ, [O III], and Hα emission lines are visible. Also shown are the values of log L_[O III] and log M_BH, where L_[O III] is in units of erg s⁻¹ and M_BH is in units of solar mass (M_⊙).
