THE PAPER Tracing Black Hole Mergers Through Radio Lobe Morphology
THE JOURNAL Science, August 23, 2002, Vol. 297
THE AUTHOR David Merritt and R.D. Ekers
The Gist What do you get when black holes meet? A really big black hole.
BEFORE TRANSLATION If the coalescence rate of binary SBHs is comparable to the galaxy merger rate, then the binary separation must be able to drop from ~1 to ~0.01 pc in a time shorter than ~1 Gy. The predicted event rate for gravitational wave interferometers should then be about equal to the integrated galaxy merger rate out to a redshift z[equals approximately]5, implying a time ...
