Merging Galaxies

I’m not sure if this is merging galaxies or just one in front of the other. This is my first time sharing an observation here. Is it possible to discern the difference just by the appearance? Is there anywhere on the web to look things like this up?

You can tell that they are merging by the fact that they don’t look like perfect spirals or elliptical galaxies. You can see that the arms are very disturbed

Nice merger! Welcome!

To be more sure, the redshift of upper right one is 0.0706451, and of the other one is 0.06975996, so almost identical, so we are reasonable sure that their distance is the same, look at SDSS DR14 Navigate Tool at SDSS DR14 Navigate Tool enter your coordinates, than click " Objects with spectra" and enjoy exploring…

And more, if you look at spectra, they both show a very prominent H-alpha, that I think could mean higt star forming activity, triggered by merging (but I shold appreciate an expert opinion!)

Thank you. This is really helpful information.

Found near a galaxy I was classifying, merging with unusual shapes
