Gravitational radiation driven supermassive black hole binary inspirals as periodically variable electromagnetic sources by Kocsis, B, Haiman, Z, Kristen Menou

“…Supermassive black hole binaries (SMBHBs) produced in galaxy mergers are thought to complete their coalescence, below separations of r_GW=10^{-3} (M_BH/10^8 M_sun)^{3/4} pc, as their orbit decays due to the emission of gravitational waves (GWs). …”

Constraints on a Tidal Charge of the Supermassive Black Hole in M87* with the EHT Observations in April 2017 by Alexander F. Zakharov

<i>H</i>₀ Tension on the Light of Supermassive Black Hole Shadows Data by Celia Escamilla-Rivera, Rubén Torres Castillejos

“…Anticipating the possibility of deeply exploring the physics of new nearby observables such as the recently detected black hole shadows, in this paper we propose standard rules to extend the studies related to these observables. Supermassive black hole shadows can be characterised by two parameters: the angular size of the shadow and the black hole mass. …”

First M87 Event Horizon Telescope Results. IV. Imaging the Central Supermassive Black Hole by The Event Horizon Telescope Collaboration

“…These images show a prominent ring with a diameter of ∼40 μas, consistent with the size and shape of the lensed photon orbit encircling the "shadow" of a supermassive black hole. The ring is persistent across four observing nights and shows enhanced brightness in the south. …”

“…Such an increasingly efficient funnelling of low-angular momentum gas to the centre of very massive halos at high redshift may account for the rapid pace at which the most massive supermassive black holes grow to reach observed masses around $10^9$M$_\odot$ at an epoch when the Universe is barely 1 Gyr old.…”

Secularly powered outflows from AGN: the dominance of non-merger driven supermassive black hole growth by Smethurst, R, Simmons, B, Lintott, C, Shanahan, J

“…Recent observations and simulations have revealed the dominance of secular processes over mergers in driving the growth of both supermassive black holes (SMBH) and galaxy evolution. Here we obtain narrowband imaging of AGN powered outflows in a sample of 12 galaxies with disk-dominated morphologies, whose history is assumed to be merger-free. …”
