From Feedback-Free Star Clusters to Little Red Dots via Compaction
Avishai Dekel, Dhruba Dutta Chowdhury, Sharon Lapiner +6
We address the origin of the Little Red Dots (LRDs) seen by JWST at cosmic morning () as compact stellar systems with over-massive black holes (BHs). We propose…
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…
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)…
The Effect of Thermal Torques on AGN Disc Migration Traps and Gravitational Wave Populations
Evgeni Grishin, Shmuel Gilbaum, Nicholas C. Stone
Accretion discs in active galactic nuclei (AGN) foster black hole (BH) formation, growth, and mergers. Stellar mass BHs migrate inwards under the influence of hydrodynamical torque…
Magnetically Dominated Disks in Tidal Disruption Events and Quasi-Periodic Eruptions
Karamveer Kaur, Nicholas C. Stone, Shmuel Gilbaum
The classical radiation pressure instability has been a persistent theoretical feature of thin, radiatively efficient accretion disks with accretion rates 1 to 100 per cent of the…
Interacting Stellar EMRIs as Sources of Quasi-Periodic Eruptions in Galactic Nuclei
Brian D. Metzger, Nicholas C. Stone, Shmuel Gilbaum
A star that approaches a supermassive black hole (SMBH) on a circular extreme mass ratio inspiral (EMRI) can undergo Roche lobe overflow (RLOF), resulting in a phase of long-lived…
Feedback-Dominated Accretion Flows
Shmuel Gilbaum, Nicholas C. Stone
We present new two-fluid models of accretion disks in active galactic nuclei (AGNs) that aim to address the long-standing problem of Toomre instability in AGN outskirts. In the spi…
Modal Decomposition of TTV - Inferring Planet Masses and Eccentricities
Itai Linial, Shmuel Gilbaum, Re'em Sari
Transit timing variations (TTVs) are a powerful tool for characterizing the properties of transiting exoplanets. However, inferring planet properties from the observed timing varia…
