Accretion-Driven Evolution of Compact-Object Populations in Gas-Rich Environments and the Origin of Massive Gravitational-Wave Sources
Mor Rozner, Alejandra Rosselli-Calderon, Enrico Ramirez-Ruiz
The origin of the most massive gravitational-wave sources remains elusive. We show that gas accretion can be understood as a transport process in mass space, causing compact object…
Sometimes You Just Can't Put a Ring on It: Setting Constraints on Rings around Moons from Magnetic Fields
Jamie M. Erak, Mor Rozner
All four giant planets and several minor bodies in the Solar System host rings. However, rings around moons have yet to be observed. A host planet can produce magnetic fields that…
The Universal Eccentricity Distribution for Dynamical Gravitational-Wave Merger Channels
Mor Rozner, Teagan A. Clarke, Isobel M. Romero-Shaw +1
We argue that all dynamical astrophysical black hole merger channels are expected to result in a common eccentricity distribution at gravitational wave (GW) frequencies relevant fo…
Gas meets Kozai: the influence of a gas-rich accretion disc on hierarchical triples undergoing von Zeipel-Lidov-Kozai oscillations
Yubo Su, Connar Rowan, Mor Rozner
Active galactic nuclei (AGNs) consist of a central supermassive black hole (SMBH) embedded in a region with both high gas and stellar densities: the gas is present as a thin accret…
Evidence for Extended Hydrogen-Poor CSM in the Three-Peaked Light Curve of Stripped Envelope Ib Supernova
Yossef Zenati, Qinan Wang, Alexey Bobrick +40
We present multi-band ATLAS photometry for SN 2019tsf, a stripped-envelope Type Ib supernova (SESN). The SN shows a triple-peaked light curve and a late (re-)brightening, making it…
Stellar distributions around supermassive black holes in gas-rich nuclear star clusters
Mor Rozner, Enrico Ramirez-Ruiz
We study the stellar distribution around supermassive black holes (SMBHs) in gas-rich nuclear star clusters (NSCs). NSCs could contain vast amounts of gas, which contribute signifi…
