Default Light from a black hole merger may have finally been spotted for thefirst time!

Normally, no light should be produced when two black holes merge,
because no light can escape them, obviously. However, in a bizarre
coincidence, two stellar mass BH's collided with each other, while they
were both also in orbit around a supermassive BH. the supermassive had
an accretion disk surrounding it, and the newly merged small BH crashed
through the accretion disk of the supermassive and sent a flare out of
the accretion disk.
