Interaction of Supermassive Black Holes with their Stellar and Dark Matter Environments [PDF]
, 2004 A review of recent theoretical work on the interactions of supermassive single and binary black holes with their nuclear environments, highlighting ways in which the observed structure of nuclei can be used to constrain the formation history of black holes.

Searching for ultra-light bosons and constraining black hole spin distributions with stellar tidal disruption events [PDF]
Nature Communications, 2022 Stellar tidal disruption events (TDEs) occur when stars pass close enough to supermassive black holes. Here, the authors show that future searches TDEs have potential to uncover the existence of ultralight bosons.

The Formation of Supermassive Black Holes and the Evolution of Supermassive Stars [PDF]
Class.Quant.Grav. 18 (2001) 3965-3976, 2000 The existence of supermassive black holes is supported by a growing body of observations. Supermassive black holes and their formation events are likely candidates for detection by proposed long-wavelength, space-based gravitational wave interferometers like LISA.

Dynamics around supermassive black holes [PDF]
, 2007 The dynamics of galactic nuclei reflects the presence of supermassive black holes (SBHs) in many ways. Single SBHs act as sinks, destroying a mass in stars equal to their own mass in roughly one relaxation time and forcing nuclei to expand.

The Role of AGN in Luminous Infrared Galaxies from the Multiwavelength Perspective
Universe, 2022 Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes.

The ngEHT’s Role in Measuring Supermassive Black Hole Spins
Galaxies, 2022 While supermassive black-hole masses have been cataloged across cosmic time, only a few dozen of them have robust spin measurements. By extending and improving the existing Event Horizon Telescope (EHT) array, the next-generation Event Horizon Telescope (

An Upper Limit on the Charge of the Black Hole Sgr A* from EHT Observations
The Astrophysical Journal, 2023 The Event Horizon Telescope (EHT) recently released an image of the supermassive black hole Sgr A* showing an angular shadow diameter d _sh = 48.7 ± 7 μ as and Schwarzschild shadow deviation $\delta =-{0.08}_{-0.09}^{+0.09}\,(\mathrm{VLTI})$ , $-{0.04}_{-

A Global Inventory of Feedback
Galaxies, 2023 Feedback from both supermassive black holes and massive stars plays a fundamental role in the evolution of galaxies and the inter-galactic medium. In this paper, we use available data to estimate the total amount of kinetic energy and momentum created ...

The contribution of supermassive black holes in stripped nuclei to the supermassive black hole population of UCDs and galaxy clusters [PDF]
MNRAS, 527, 4643-4656 (2024), 2023 We use the hydrodynamic EAGLE simulation to predict the numbers and masses of supermassive black holes in remnant nuclei of disrupted galaxies (stripped nuclei) and compare these to confirmed measurements of black holes in observed ultra-compact dwarf galaxies (UCDs).
