Through the hoop?


I think the elliptical galaxy is in front of the spiral galaxy.

Perhaps, only 1 redshift is known

However, there seems to be disturbance / the spiral arm on top is extended a lot, asymmetry

Guess we have to figure out the redshift to the other galaxy.

Both have spectroscopic redshift measurements. 0.16767 and 0.19341 for the northern and southern components respectively

Nice, thanks! Couldn’t find them.

Guess that indeed mean overlap then.
