Fig. 1

Optical image of UGC 2489 taken from the Sloan Digital Sky Survey (SDSS, Aihara et al. 2011) showing its multi-component core structure. The red intensity overlay shows a 4885 MHz VLA archival image. In yellow we over-plot contours from a 1415 MHz VLA archival image. Contours are log scaled, there are 10 contour levels going from 4σ to 500σ. Details about the VLA images can be found in Table 1. The stellar halo around the cores is roughly 40 kpc in extent. The position of the core hosting the AGN is shown with a black cross.
