Strange Merger (+AGN?)

Can someone who knows more offer insight into what is going on here? The blue (starforming?) galaxy at bottom is extremely bright--does that indicate an AGN / quasar? Also the blue object's shape is unusual, with an S-curved arm above. Is this just a tidal disturbance? I've never seen such an INTENSELY bright blue galaxy before! Thanks for any insights or explanations!

Looks amazing.

The graph indicates a slight AGN, and alot of dust, which is usual for an edge-on galaxy.
The spectral chart for the bright object indicates an AGN, though I think the image is overexposed, and it isn't really that bright. Lots of star formation, that will be C-shaped blue object.
The galaxies might be merging. http://iopscience.iop.org/article/10.1086/381954/pdf
