    This BLRG/FRII is found to have about two-thirds of its near-infrared K-band flux in an unresolved nuclear component (Inskip et al. 2010). The galaxy appears to be in a dense environment, with several companions within ∼20 arcsec. Our Gemini GMOS-S image reveals a faint and long tidal tail of surface brightness μV = 26.2 mag arcsec−2 extending up to 40 kpc to the NW — this is the faintest tidal feature detected in our imaging survey (Ramos Almeida et al. 2011a). In the K-band images shown in Inskip et al. (2010), the galaxy appears elongated in the direction of the tidal tail. However, due to the faintness of the latter feature, it is not clearly detected in the near-IR. Our long-slit spectrum of the galaxy does not allow us to confirm/discard the emission-line nature of this tail.

    PKS 0038+09 has a rich emission-line spectrum, with an extremely high ionization state, a strong broad Hα component, and hints of broad wings to the Hα line. There are no clear detections of stellar absorption features. The emission lies may be slightly extended.  Direct AGN light is likely to contribute much of the UV excess in this BLRG, which has a low UV polarization (Tadhunter et al. 2002).

   From the extrapolation of the high frequency radio core component towards the infrared region of the spectral energy distribution, Dicken et al. (2008) find evidence that the non-thermal core synchrotron emission may contaminate the MFIR flux in this radio galaxy.
