As Ranyart suggest,
Indeed In between two Black Holes a star is able to form by the vacuum cleaning effect of the two black holes.
This is supposed to be the mechanism in all Open star clusters, and the start of Early Galaxies seen in the deep field .
Cygnus A is a nice example of a newborn STAR!!!and the GAS in between two black holes, I must admit that this is not the common explanation for Cygnus A.
Look at it, how the two black holes repell masses of gas into the nuclear white hole regeon.
