ARG00018wc Is it 2 galaxies at same location North? What is the cause of the South radio contour?

North SDSS J153739.91+382122.2 & SDSS J153739.95+382123.6 7 South contour from what?

The automated SDSS photometric pipeline sometimes has difficulty with galaxies with dust lanes ... in this case the lower (S) photometric object corresponds to the galaxy's nucleus, and it's a spectroscopic object too (the N object is an artifact).

The radio source to the SSE is #elongated, perhaps it's a #corejet or an almost-#hourglass? The host is, I think, zph 0.470±0.045 SDSS J153741.46+382051.2:

I too suspect that the 2 radio components belong to 2 different radio galaxies.
