Black
hole coalescences aren't expected to generate light that could be spotted by telescopes, but another prime candidate could: a smashup between two remnants of stars known as neutron stars.

«All observations until the last one were from the
coalescence of binary black
hole systems,» Lazzati said.
These findings were published in Physical Review Letters the week of October 11 in a paper titled «Formation and
Coalescence of Cosmological Supermassive - Black -
Hole Binaries in Supermassive - Star Collapse.»
LIGO can only do it by solving GR for the gravitational waves from a spinning black
holes before, during and after
coalescence, and comparing that both to signals from non-spinning black
holes and their actual data.
Now, technically the earlier event, GW150914, also observed a Kerr black
hole, as the final black
hole after
coalescence had spin (by conservation of angular momentum, since it was created from a pair of mutually - orbiting black
holes).
The inferred source of both events is the
coalescence of a stellar mass binary black
hole system at cosmological distances.
«We have observed — on the 4th of January, 2017 — another massive black
hole - black
hole binary
coalescence; the in - spiral and merging of black
holes 20 and 30 times the mass of our sun,» Dave Shoemaker, a senior research scientist who works at Massachusetts Institute of Technology (MIT) and the spokesperson for the LIGO Scientific Collaboration, told reporters during a special news briefing on Wednesday (May 31).
The LIGO Scientific Collaboration and the VIRGO Collaboration are proud to jointly - announce the detection of a third gravitational - wave event: GW170104, yet another
coalescence of two stellar - mass black
holes.
