Square shaped elliptical galaxy

What causes this galaxy to look like this?

I remember there was some press coverage over a rectangular galaxy (LEDA 074886). Not sure if this is similar. Could just be weird shape going on due to interaction effects.

yeah, you are right, here is the article:

This one seems to be distant from the other galaxies, with which it could’ve collided. Do you see anything around?

If its a late stage merger, they wouldnt be 2 resolved objects.

Makes sense.
Since there was a publication, I was wondering if it worth reporting this galaxy somewhere?

Could try galaxy zoo I guess
