Default ASTRO: UGC 4352 A possible triple galaxy

UGC 4352 is either a 2 or 3 galaxy system. NED only lists 2. What the
UGC is seeing I don't know. It isn't UGC 4349 to the north as the UGC
says of it: "Paired with triple system UGC 4352." There is a odd oval
plume-like feature by UGC 4352 NED01. UGC 4352 NED02 has an obvious
orange core and a bright blue region to its east. Also there's a near
star-like object to the northwest of the core (UGC 04352b part of galaxy
per NED). UGC 04352 has the appearance of a galaxy merger that is or
nearly is complete. Any of these could be what the UGC sees.

The UGC also lists a UGC 4352c. Unfortunately the position has a 3.5"
error circle. That could encompass either the blue object I mentioned
or the orange core. The position given is between the two but closer to
the core. Oh yes there is no UGC 4352a. I wish they were more
definitive. I'm going to go with UGC 4352b being the third member and c
being the core of NED02 with a position error. But is b a separate
galaxy or part of the galaxy as NED says. Is it the remains of the core
of a devoured galaxy? I lean toward the latter.

UGC 04352 NED01 is classed as an Sc spiral and is seen edge on. I
didn't resolve a dust lane. UGC 04352 NED02 is classed as Sa. I'd tack
a peculiar onto to that considering that odd radial red dust lane. Or
is that dust in the plane of UGC 4352 NED01? While the redshift of UGC
4352NED01 is greater than that of the companion it does appear to lie in
front of it. At least I see no obscuring from the stars in the disk of
the companion I'd expect if it were behind the companion galaxy. I
doubt the dust is related to the edge on but it is odd how it lies in
the same plane. This is one I wish Hubble would take a look at!
Unfortunately I found nothing at the HST Legacy site.

Very few other galaxies are even identified, far fewer with redshift
data. Even though the Sloan survey covered this field NED has little on
it. I'd really like to know about the odd object(s) south southeast of
UGC 4352. Unfortunately it isn't listed. I've marked it with a
question mark. There appears to be a faint plume to the west from the
north end. Is it two galaxies in collision? Just too far away to tell
much. The Sloan image doesn't appear to pick up the plume. It's seen
in all sub frames. I suppose it could be a reflection but not like any
I've seen before so think it real. I sometimes pick up plumes the SDSS
doesn't. This may be one.

This one was suggested to me by Sakib Rasool.

Rick,

I guess the companion galaxy could be mistaken for a jet...
Although this would have to be a giant jet...
