BUMP: Body-driven Unified Multi-object Physics for HOI Synthesis
Wonjung Woo, Hyeonwoo Kim, Hanbyul Joo
Generating human-object interactions (HOIs) with multiple objects is challenging because the resulting motions arise from different underlying causes. Human motion reflects semanti…
The effect of pressure confinement on the maximum mass of rapidly accreting supermassive stars
Lorenz Zwick, Christopher Tiede, Zoltán Haiman
We derive an extension of Chandrasekhar's pulsational stability criterion for relativistic stars with a pressure boundary condition at the surface. We then apply the new criterion…
Electromagnetic Emission and Orbital Evolution of Eccentric Supermassive Black Hole Binaries in Retrograde Disks
David ONeill, Mark J. Avara, Christopher Tiede +3
Circumbinary disks around supermassive black hole binaries (SMBHBs) are expected to form across a broad range of inclinations, with retrograde configurations potentially a common o…
Hot, cold, and multi-component accretion flows around supermassive black hole binaries
Christopher Tiede, Daniel J. D'Orazio
We develop a model for supermassive black hole binaries (SMBHBs) accreting below their Eddington limit, focusing on systems where hot, advection-dominated flows become viable. We s…
Gravitational Wave Decoupling in Retrograde Circumbinary Disks
David O'Neill, Christopher Tiede, Daniel J. D'Orazio +2
We present a study of the late-time interaction between supermassive black hole binaries and retrograde circumbinary disks during the period of gravitational wave-driven inspiral.…
Stellar Stripping and Disruption in Disks around Supermassive Black Hole Binaries: Repeating nuclear transients prior to LISA events
Daniel J. D'Orazio, Christopher Tiede, Lorenz Zwick +2
If supermassive black hole binaries (SMBHBs) are driven together by gas disks in galactic nuclei, then a surrounding nuclear star cluster or in-situ star-formation should deliver s…
Suppressed accretion onto massive black hole binaries surrounded by thin disks
Christopher Tiede, Jonathan Zrake, Andrew MacFadyen +1
We demonstrate that gas disks around binary systems might deliver gas to the binary components only when the circumbinary disk is relatively warm. We present new grid-based hydrody…
Accretion mediated spin-eccentricity correlations in LISA massive black hole binaries
Mudit Garg, Christopher Tiede, Daniel J. D'Orazio
We examine expected effective spin () and orbital eccentricity () correlations for a population of observable equal-mass massive black hole bina…
Fast Methods for Computing Photometric Variability of Eccentric Binaries: Boosting, Lensing, and Variable Accretion
Daniel J. D'Orazio, Paul C. Duffell, Christopher Tiede
We analyze accretion-rate time series for equal-mass binaries in co-planar gaseous disks spanning a continuous range of orbital eccentricities up to 0.8, for both prograde and retr…
The Santa Barbara Binary-Disk Code Comparison
Paul C. Duffell, Alexander J. Dittmann, Daniel J. D'Orazio +13
We have performed numerical calculations of a binary interacting with a gas disk, using eleven different numerical methods and a standard binary-disk setup. The goal of this study…
Long-term Evolution of Binary Orbits Induced by Circumbinary Disks
Ruggero Valli, Christopher Tiede, Alejandro Vigna-Gómez +6
Circumbinary disks are found in a variety of astrophysical scenarios, spanning binary star formation to accreting supermassive black hole binaries. The interaction with a circumbin…
Disk induced binary precession: Implications for dynamics and multi-messenger observations of black hole binaries
Christopher Tiede, Daniel J. D'Orazio, Lorenz Zwick +1
Many studies have recently documented the orbital response of eccentric binaries accreting from thin circumbinary disks, characterizing the change in binary semi-major axis and ecc…
Eccentric Binaries in Retrograde Disks
Christopher Tiede, Daniel J. D'Orazio
Modern numerical hydrodynamics tools have recently enabled detailed examinations of binaries accreting from prograde circumbinary disks. These have re-framed the current understand…
How Binaries Accrete: Hydrodynamic Simulations with Passive Tracer Particles
Christopher Tiede, Jonathan Zrake, Andrew MacFadyen +1
Linear analysis of gas flows around orbiting binaries suggests that a centrifugal barrier ought to clear a low-density cavity around the binary and inhibit mass transfer onto it. M…
Equilibrium eccentricity of accreting binaries
Jonathan Zrake, Christopher Tiede, Andrew MacFadyen +1
Using high-resolution hydrodynamics simulations, we show that equal-mass binaries accreting from a circumbinary disk evolve toward an orbital eccentricity of , unles…
Gas-driven inspiral of binaries in thin accretion disks
Christopher Tiede, Jonathan Zrake, Andrew MacFadyen +1
Numerical studies of gas accretion onto supermassive black hole binaries (SMBHBs) have generally been limited to conditions where the circumbinary disk (CBD) is 10-100 times thicke…
