Black holes emit radiation, but I believe in this case is simply the rapid decrease in visible light is the mystery.
7-8 months from "normal" to dimmed enough to comment on it is pretty quick on a galactic timescale. I can't imaging something smashing an accretion disk or blocking it in that short a time that wouldn't have raised it's own red flags.

I was wondering how it went dark, it's a black hole after all?
I assume it emits some radio spectrum that diminished?
