Is this an overlapping ellipsoidal and spiral, or the remains of a merger?
Got no idea
It does look like a bit of a hybrid, between an elliptical and a spiral, doesn't it? 😄
Without further analysis, it's impossible to say, with any certainty, whether it's a somewhat unusual/disturbed spiral or a late-stage merger (or something else entirely).
However, the SDSS DR9 automated spectrum pipeline classifies it as "GALAXY BROADLINE", which points to an elevated likelihood that it's a merger ...
Hope this helps, and happy hunting! 😃
