Radio Galaxy Zoo Talk

ARG00024od - what's going on here?

    From the Suggestions for RGZ Objects to show with detailed FIRST contours overlaid on SDSS images thread, started by WizardHowl:

    [Dolorous Edd] How about this one? http://radiotalk.galaxyzoo.org/#/subjects/ARG00024od

    Are the SW FIRST sources artifacts (there's no apparent NVSS emission)?

    Dolorous Edd suggested three possible hosts: SDSS J072707.76+233359.1 (left; the bright STAR*), SDSS J072707.18+233401.1 (center; z_ph 0.671 ± 0.1818/0.179 ± 0.2196), and SDSS J072707.73+233403.6 (right; z_ph 0.309 ± 0.2626/0.109 ± 0.1433):

    Perhaps a zoomed-in overlay might help, to look at what optical sources there are within the main NVSS blob?

    *according to NED, it's a GALEX source, GALEXASC J072707.76+233359.4

    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 per the ARG image (left; J2000.0).

    From the overlay, suspect SDSS J072714.47+233555.2 Z_ph~0.27 which may be interacting with immediate neighbour.

    SDSS J072714.47+233555.2; are the red tails real?:

    Is this apparently merging/interacting pair the host of the radio emission?

Image center (J2000.0) is the galaxy SDSS J072714.47+233555.2; "z_ph" its SDSS photometric redshift.
