J233300.93+010045.7 - a single object or 3 unrelated sources?

  • JeanTate by JeanTate

    From page 6 of the Interesting things from NVSS survey thread, by Dolorous Edd:

    Not sure what it is .. a single object or 3 unrelated sources

    The compact source FIRST/ NVSS is SDSS J233300.93+010045.7 or SDSS J233301.07+010045.2

    I have been unable to find a ARG ID for the FIRST source in the center. Here is a FIRST and NVSS overlay on an SDSS image, centered on z_sp 0.982 (small delta chi^2!) SDSS J233300.93+010045.7:

    And a zoomed-in FIRST overlay:

    The host is strange:

    As is the spectrum:

    UPDATE (23 August, 2014): the object (host) is in SDSS DR7, and the redshifts of the strongest cross-correlations peaks (by template) in the spectrum are
    0.719 (26, 27), 0.806 (28), 2.235 (29), 1.056 (30), 1.054 (31), and 3.780 (32) 😮. That it's an AGN of some kind seems clear; but what kind? and at what redshift?

    Boilerplate: SDSS images 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 J233300.93+010045.7; "z_sp" its SDSS spectroscopic redshift.
