Active galaxies give off bright radiation from their cores, where gas heats up as it is compressed into a swirling accretiondisk encircling the black hole.
We'd be able to connect a lot of the physics happening within the gaseous environment and accretiondisk to the binary black hole merger to the gravitational radiation.
