ARG0003284 - host a giant z~0.5 ETG with odd morphology

  • JeanTate by JeanTate

    SDSS J222552.80+101316.7 has a perfectly boring dead and red z_sp 0.507 SDSS spectrum ... but it's pretty darn big, and bright, and looks, um, quite unlike a giant elliptical:

    Radio-wise it's a fading corejet, right? Or not ...

    Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) and NVSS (cyan) contours derived from FITS files produced using SkyView with Python code described in this RGZ Talk thread. Image center (J2000.0) is the galaxy SDSS J222552.80+101316.7; "z_sp" its SDSS spectroscopic redshift.

    Not enough to really classify. NVSS suggests there's significant flux missing from the west, beyond what you can see in FIRST. Galaxy is about as disturbed as I've ever seen.

    Really pushing NVSS contours into the noise ...

    And zooming out:

    No sign of detached lobes, further out 😦
