If the larger componant is claimed to be the most massive SMBH, shouldn't the article say how massive it is? It says it's six times the previous most massive object known, and it says how massive it's companion is, and it explains how the mass was calculated, but it never says what the mass is.StevoDog21 (talk) 19:17, 25 May 2009 (UTC)

Relative mass of the black holes[edit]

The article's wording is a bit inconsistent. In one place, it states: "This kind of variation suggests[7] that an engine is a binary supermassive black hole of two black holes of similar size." but then does on to say: "The smaller supermassive black hole with a mass of only 100 million MSun orbits the larger one with an observed 11-12 year orbital period." Is a factor of 10–20 difference in mass still considered "similar", for the purposes of this article? My gut reaction says no, but I'd like to hear other thoughts.

Absolute rotation rate?[edit]

The rotation as the Kerr parameter fraction should be seconded by one in absolute metric units (eg Hz) — Preceding unsigned comment added by (talk) 13:28, 11 March 2016 (UTC)
