Active Galactic Nucleus Tori: Potential Birthplace to Millions of Planets

Bhupendra Mishra, Wladimir Lyra, Barry McKernan +3

The outer regions of AGN disks have temperatures similar to those of circumstellar disks, permitting dust condensation. Therefore, planet formation and growth could be active in th…

AGN Disks as Supernova Mufflers I: 3D Local Hydrodynamic Models

Harrison E. Cook, Wladimir Lyra, Mordecai-Mark Mac Low +2

Supernova (SN) shocks that originate from stars on orbits embedded in dense active galactic nuclei (AGN) accretion disks evolve differently from those that occur in the interstella…

McFACTS. IV. Electromagnetic Counterparts to AGN-disk-embedded Binary Black Hole Mergers

Emily McPike, Rosalba Perna, K. E. Saavik Ford +10

The accretion disks of active galactic nuclei (AGNs) are promising environments for producing binary black hole (BBH) mergers, which have been detected via gravitational waves (GWs…

McFACTS II: Mass Ratio--Effective Spin Relationship of Black Hole Mergers in the AGN Channel

Harrison E. Cook, Barry McKernan, K. E. Saavik Ford +6

We use the Monte Carlo For AGN (active galactic nucleus) Channel Testing and Simulation (McFACTS, https://www.github.com/mcfacts/mcfacts) code to study the effect of AGN disk and n…

Prospects for the formation of GW231123 from the AGN channel

V. Delfavero, S. Ray, H. E. Cook +6

The recent binary black hole (BBH) merger GW231123 consisted of the merger of two intermediate mass black holes (IMBH) which appear to have large spin magnitudes. Active galactic n…

McFACTS I: Testing the LVK AGN channel with Monte Carlo For AGN Channel Testing & Simulation (McFACTS)

Barry McKernan, K. E. Saavik Ford, Harrison E. Cook +6

Active galactic nuclei (AGN) are a promising source of the binary black hole (BBH) mergers observed in gravitational waves with LIGO-Virgo-Kagra (LVK). Constraining the AGN channel…
