Possible lens?

  Blue-ish color. Looks like interaction / tidal debris, but redshift of both galaxies is different.

  Known lenses look incradible thin in comparison, so likely not.

  Still interesting blue halo for a yellow elliptical. Looks too large to be overlap so possibly massive tidal debris from a past merger. Or the error margin from PhotoZ is incorrect.
