NASA's Swift satellite appears to have confirmed one reason why a small percentage of supermassive black holes throw out vastly elevated levels of energy: it's provoked by violent collisions between galaxies. NASA explains that one per cent of such black holes - weighing in at "between a million and a billion times the Sun's …
No, no, no!
It's just god* turning the lights on and off !!!

Where there's blame there's a claim!
I would NOT like to be the insurance company for these, as no doubt there will be TV adverts for this very soon!
Intergalactic pile-ups are why we need more average speed cameras, natch.
When galaxies collide
I pity the poor aliens who once inhabited these galaxies. Or, if you will, the galaxians.
the swift bat will solve many problems and answer many questions
holy collision, bat-man!
i'm already sorry i said that....
hmmm x-rays, you say?
I wonder how they decided whether these photons they're looking at were x-rays instead of gamma rays. As I recall, the difference between the two is how they're made: gamma rays for chemical radioactive sources, x-rays for electric sources. They didn't get to "Colliding Galaxies" as a source for either...
But then, they're calling them "hard" and "soft," so perhaps they don't really care what the proper name is...
Re : hmmm x-rays, you say?
Gamma are higher frequency than x-rays although there can be considerable overlap
