JWST Observations of the Double Nucleus in NGC 4486B: Possible Evidence for a Recent Binary SMBH Merger and Recoil
Behzad Tahmasebzadeh, Monica Valluri, Shashank Dattathri +19
A recent study of the compact elliptical galaxy NGC 4486B using JWST-NIRSpec IFU kinematics confirmed a supermassive black hole (SMBH) of mass (~8% of…
Tertiary Tides with Eccentric Orbits
Yan Gao, Tjarda Boekholt, Devismita Panda +2
Within hierarchical triple stellar systems, there exists a tidal process unique to them, known as tertiary tides. In this process, the tidal deformation of a tertiary in a hierarch…
A JWST View of the Overmassive Black Hole in NGC 4486B
Behzad Tahmasebzadeh, Matthew A. Taylor, Monica Valluri +19
We present a new stellar dynamical measurement of the supermassive black hole (SMBH) in the compact elliptical galaxy NGC 4486B, based on integral field spectroscopy with JWST/NIRS…
On the Formation of S-stars from a Recent Massive Black Hole Merger in the Galactic Center
Tatsuya Akiba, Smadar Naoz, Ann-Marie Madigan
The Galactic Center hosts a rotating disk of young stars between 0.05 and 0.5 pc of Sgr A*. The ``S-stars'' at a distance pc, however, are on eccentric orbits with nearly i…
Counter-Rotation and Slow Precession in Aligned Eccentric Nuclear Disks due to Gravitational Wave Recoil Kicks
Jane C. Bright, Tatsuya Akiba, Ann-Marie Madigan
The M31 nucleus contains a supermassive black hole embedded in a massive stellar disk of apsidally-aligned eccentric orbits. It has recently been shown that this disk is slowly pre…
Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick
Tatsuya Akiba, Selah McIntyre, Ann-Marie Madigan
The surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and o…
