Jet? Multiple bodies. Oxygen signature

Well, I’m not sure what I’m looking at here. It looks interesting. I don’t think this is a simple merger. There’s spectra for one segment of the galaxy with a strong emission line near 5000ang, which I take to be an oxygen signature typical maybe of strong star formation? But there seems like there’s more going on here, like a jet pattern maybe? I can’t even tell how many bodies are involved, but it looks interesting.

I’d guess a galaxy merger, where the smaller one has been mostly ripped apart – its core is at the 7 o’clock position.

In the 7 o’clock direction looks like the “umbrella” shaped tidal features, like the feature in

at 1 o’clock.
