ARG0000rvo - 3, 2, or 1 unrelated radio sources (in center)?
The bright, almost linear WISE core is a chain of galaxies* in SDSS:
The brightest one, SDSS J073541.07+464228.1, is z_sp 0.485; the others have consistent z_ph
The N (of the central sources) may have z_ph 0.47 SDSS J073540.37+464249.5 as host; it's small, faint, and possibly green
*though SDSS thinks only ~3 are galaxies! 😮

Really no way to tell without higher resolution in the radio. Pretty clearly some kind of disturbed radio galaxie(s) associated with the distant group/cluster.
SDSS J073541.98+464230.7, z_ph 0.378±0.0605/0.455±0.1118, in the center seems to be just another high-z (for SDSS) boring elliptical, albeit in an interesting chain:
Radio-emission wise? See for yourself:
Boilerplate: SDSS image per
http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) contours derived from the FITS file produced using SkyView with Python code described in this RGZ Talk thread. Image center (J2000.0) is the galaxy SDSS J073541.98+464230.7; "z_ph" its SDSS photometric redshift.
