Beautiful example of two spiral galaxies near each other, each a radio source. Not (yet) merging. CLick on SDSS link to see the galaxies.

The two galaxies are SDSS J103329.72+440434.2 (in the center) and SDSS J103331.62+440421.2 (to the lower left, or SE). They both have a spectroscopic redshift of 0.052, which is consistent with them being interacting. As are their spectra, which show strong emission lines, indicative of activity in their nuclei, triggered no doubt by their interaction.

As DocR says, this is a very nice pair; here's what they look like in SDSS:

Hope this helps, and happy hunting! 😃
