The accretion discs of the BH masses for which LIGO (and Virgo) is most sensitive will generally be fairly sparse, so the emissions will generally be fairly dim. For a pair of similar-mass neutron stars (NS) that merge into a BH, you can treat region of spacetime close to the merger as being filled with extremely dense accretion discs. The density of matter leads very bright emissions, and the available geodesics produce radiation that will escape to infinity rather than being…</p><p><a href="https://hackerpaper.kaipfister.de/p/1001.3074/">Paper and discussion history</a>.
