A) antimatter and matter colliding at the center of a galaxy
B) chain reactions of supernova explosions
C) matter falling toward a supermassive black hole at the center of a galaxy
D) the left-over (and stored) energy of the big bang explosion
E) you can't fool me; astronomers have no explanation for what the energy source is for the quasars -- they are completely baffled
