Constraining Ultralight Scalars with Black Hole Binary Mergers in Galactic Nuclei
Majed Khalaf, Eric Kuflik, Alessandro Lenoci +2
Ultralight scalars can form long-lived, macroscopic bound states around spinning black holes, known as superradiance clouds. These clouds provide an additional channel for energy d…
Anisotropic wind in tidal disruption events
Paola Martire, Elena Maria Rossi, Nicholas Chamberlain Stone +2
Over the coming years, the number of tidal disruption events (TDEs) is expected to substantially increase with observations from the Vera Rubin Observatory (g and r band) and {\it…
Intermediate States in Chaotic Triple Evolution and Applications to Black Hole Merger Statistics
Dina Meylakh, Nicholas C. Stone, Nathan W. C. Leigh
Three-body interactions exhibit phases of strong chaotic evolution as well as hierarchical motion where one body separates from a binary and follows a hyperbolic or elliptic trajec…
Wind-mediated Eddington-limited emission in a Black Hole Tidal Disruption Event
Paola Martire, Elena Maria Rossi, Nicholas Chamberlain Stone +3
Observations of tidal disruption events (TDEs) have already produced tens of strong candidate flares, and their number will greatly increase with upcoming wide field surveys. Never…
Fragmentation in Collapsar Disks: Migration, Growth, and Emission
Y. Lerner, N. C. Stone, D. D. Ofengeim
We present a parameter survey of fragmentation in collapsar disks, using a revised version of the Chen & Beloborodov (2007) model that determines the structure of steady state hype…
Disruptions of stars and binary systems on chaotic orbits in an axisymmetric Milky Way center
Zephyr Penoyre, Elena Maria Rossi, Nicholas C. Stone
Non-spherical potentials allow a wide range of trajectories, both regular and chaotic, whose periapse distances can vary orbit to orbit. In particular chaotic trajectories can brin…
Late-Time Evolution of Magnetized Disks in Tidal Disruption Events
Yael Alush, Nicholas C. Stone
In classic time-dependent 1D accretion disk models, the inner radiation pressure dominated regime is viscously unstable. However, late-time observations of accretion disks formed i…
Counting the Unseen II: Tidal Disruption Event Rates in Nearby Galaxies with REPTiDE
Christian H. Hannah, Nicholas C. Stone, Anil C. Seth +1
Tidal disruption events (TDEs) are a class of transients that occur when a star is destroyed by the tides of a massive black hole (MBH). Their rates encode valuable MBH demographic…
The unreasonable effectiveness of the approximation
Elisha Modelevsky, Nicholas C. Stone, Re'em Sari
In kinetic theory, the classic approach calculates the rate of particle interactions from local quantities: the number density of particles , the cross-section , and t…
How to Escape from a Trap: Outcomes of Repeated Black Hole Mergers in AGN
Shmuel Gilbaum, Evgeni Grishin, Nicholas C. Stone +1
Stellar-mass black holes (BHs) embedded in active galactic nuclei (AGN) may be major sources of astrophysical gravitational waves (GWs), contributing both to the observed LIGO-Virg…
Resonant Capture of Stars by Black Hole Binaries: Extreme Eccentricity Excitation
Omri Reved, Lazar Friedland, Nicholas C. Stone
Massive black hole (MBH) binaries in galactic nuclei are one of the leading sources of mHz gravitational waves (GWs) for future missions such as . Howeve…
Growth of Massive Black-Holes in FFB Galaxies at Cosmic Dawn
Avishai Dekel, Nicholas C. Stone, Dhruba Dutta Chowdhury +4
The scenario of feedback-free starbursts (FFB), which predicts excessively bright galaxies at cosmic dawn as observed using JWST, may provide a natural setting for black hole (BH)…
Elevated Rates of Tidal Disruption Events in Active Galactic Nuclei
Karamveer Kaur, Nicholas C. Stone
Advances in time domain astronomy have produced a growing population of flares from galactic nuclei, including both tidal disruption events (TDEs) and flares in active galactic nuc…
Repeating partial disruptions and two-body relaxation
Luca Broggi, Nicholas C. Stone, Taeho Ryu +4
Two-body relaxation may drive stars onto near-radial orbits around a massive black hole, resulting in a tidal disruption event (TDE). In some circumstances, stars are unlikely to u…
Formation of an Accretion Flow
Clément Bonnerot, Nicholas Stone
After a star has been tidally disrupted by a black hole, the debris forms an elongated stream. We start by studying the evolution of this gas before its bound part returns to the o…
Tidal Disruption Disks Formed and Fed by Stream-Stream and Stream-Disk Interactions in Global GRHD Simulations
Zachary L. Andalman, Matthew T. P. Liska, Alexander Tchekhovskoy +2
When a star passes close to a supermassive black hole (BH), the BH's tidal forces rip it apart into a thin stream, leading to a tidal disruption event (TDE). In this work, we study…
The Process of Stellar Tidal Disruption by Supermassive Black Holes. The first pericenter passage
Elena M. Rossi, Nicholas C. Stone, Jamie A. P. Law-Smith +4
Tidal disruption events (TDEs) are among the brightest transients in the optical, ultraviolet, and X-ray sky. These flares are set into motion when a star is torn apart by the tida…
Probing the Cosmological Evolution of Super-massive Black Holes using Tidal Disruption Flares
Dheeraj R. Pasham, Dacheng Lin, Richard Saxton +5
The question of how supermassive black holes (SMBHs) grow over cosmic time is a major puzzle in high-energy astrophysics. One promising approach to this problem is via the study of…
