Examples of type 2 AGN hosts with tidal features, which have low E(B − V) < 0.4. The two left columns show AGNs with low log L_[O III] < 41.1, while the two right columns display those with high log L_[O III] > 41.4. First row: SDSS color images. The galaxy ID is displayed on each image, and a horizontal bar indicates the angular scale of the image. Second row: r-band deep images from the DESI Legacy Imaging Survey, displayed at the same angular scale as the color images in the first row. These images are shown in inverted grayscale after Gaussian smoothing with σ = 2 pixels. Third row: Optical spectra of type 2 AGNs covering the observed wavelength range of 4700–7400Å, where the Hβ, [O III], and Hα emission lines are visible. The corresponding values of log L_[O III] (erg s⁻¹) and E(B − V) are also indicated.
