In-plane Tidal Disruption of Stars in Disks of Active Galactic Nuclei
Taeho Ryu, Barry McKernan, Saavik Ford +4
Stars embedded in active galactic nucleus (AGN) disks or captured by them may scatter onto the supermassive black hole (SMBH), leading to a tidal disruption event (TDE). Using the…
Tidal Disruption Events by Compact Supermassive Black Hole Binaries
Taeho Ryu, Alessandro A. Trani, Nathan W. C. Leigh
Stars can be tidally destroyed or swallowed by supermassive black hole binaries. Using a large number of accurate few-body simulations, we investigate the enhancement and suppressi…
Starfall: A heavy rain of stars in 'turning on' AGN
B. McKernan, K. E. S. Ford, M. Cantiello +5
As active galactic nuclei (AGN) `turn on', some stars end up embedded in accretion disks around supermassive black holes (SMBHs) on retrograde orbits. Such stars experience strong…
Symmetry Breaking in Dynamical Encounters in the Disks of Active Galactic Nuclei
Yihan Wang, Barry McKernan, Saavik Ford +3
Active galactic nucleus (AGN) disks may be important sites of binary black hole (BBH) mergers. Here we show via numerical experiments with the high-accuracy, high precision code {\…
Spin misalignment of black hole binaries from young star clusters: implications for the origin of gravitational waves events
Alessandro Alberto Trani, Ataru Tanikawa, Michiko S. Fujii +2
Recent studies indicate that the progenitors of merging black hole (BH) binaries from young star clusters can undergo a common envelope phase just like isolated binaries. If the st…
Massive Stellar Triples Leading to Sequential Binary Black-Hole Mergers in the Field
Alejandro Vigna-Gómez, Silvia Toonen, Enrico Ramirez-Ruiz +3
Stellar triples with massive stellar components are common, and can lead to sequential binary black-hole mergers. Here, we outline the evolution towards these sequential mergers, a…
AGN as Potential Factories for Eccentric Black Hole Mergers
J. Samsing, I. Bartos, D. J. D'Orazio +6
There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity. In addition, the component black holes' masses exceeded the limit predicted by st…
Evolution of Retrograde Orbiters in an AGN Disk
Amy Secunda, Betsy Hernandez, Jeremy Goodman +4
AGN disks have been proposed as promising locations for the mergers of stellar mass black hole binaries (BBHs). Much recent work has been done on this merger channel, but the major…
Orbital Migration of Interacting Stellar Mass Black Holes in Disks around Supermassive Black Holes II. Spins and Incoming Objects
Amy Secunda, Jillian Bellovary, Mordecai-Mark Mac Low +6
The masses, rates, and spins of merging stellar-mass binary black holes (BBHs) detected by aLIGO and Virgo provide challenges to traditional BBH formation and merger scenarios. An…
The X-ray Emissivity of Low-Density Stellar Populations
C. O. Heinke, M. G. Ivanov, E. W. Koch +17
The dynamical production of low-mass X-ray binaries and brighter cataclysmic variables (CVs) in dense globular clusters is well-established. We investigate how the X-ray emissivity…
Electromagnetic transients and gravitational waves from white dwarf disruptions by stellar black holes in triple systems
Giacomo Fragione, Brian D. Metzger, Rosalba Perna +2
Mergers of binaries comprised of compact objects can give rise to explosive transient events, heralding the birth of exotic objects which cannot be formed through single star evolu…
Constraining the Black Hole Initial Mass Function with LIGO/VIRGO Observations
Rosalba Perna, Yi-Han Wang, Will M. Farr +2
Prior to the detection of black holes (BHs) via the gravitational waves (GWs) they generate at merger, the presence of BHs was inferred in X-ray binaries, mostly via dynamical meas…
Orbital Migration of Interacting Stellar Mass Black Holes in Disks around Supermassive Black Holes
Amy Secunda, Jillian Bellovary, Mordecai-Mark Mac Low +5
The merger rate of stellar-mass black hole binaries (sBHBs) inferred by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) suggests the need for an efficient s…
Implementing Tidal and Gravitational Wave Energy Losses in Few-body Codes: A Fast and Easy Drag Force Model
Johan Samsing, Nathan W. C. Leigh, Alessandro A. Trani
We present a drag force model for evolving chaotic few-body interactions with the inclusion of orbital energy losses, such as tidal dissipation and gravitational wave (GW) emission…
On stellar-mass black hole mergers in AGN disks detectable with LIGO
B. McKernan, K. E. S. Ford, J. Bellovary +9
Black hole mergers detectable with LIGO can occur in active galactic nucleus (AGN) disks. Here we parameterize the merger rates, the mass spectrum and the spin spectrum of black ho…
