The Role of Inhomogeneities in the Turbulent Accretion of Black Holes

The Astrophysical Journal
Observations of supermassive black holes by the Event Horizon Telescope reveal significant inhomogeneities, most likely related to density and magnetic field perturbations.

Connecting Cores and Black Hole Dynamics across Scales: From Globular Clusters to Massive Ellipticals

The Astrophysical Journal Letters
The centers of massive elliptical galaxies exhibit a wide range in density profiles, from central cusps to resolved cores with order kiloparsec sizes.

SUPERMASSIVE BLACK HOLE AT THE GALACTIC CENTER

New Results and Actual Problems in Particle & Astroparticle Physics and Cosmology, 2014
We derive an analytical expression of a shadow size as a function of a charge in the Reissner - Nordstr?m (RN) metric. Using the derived expression we consider shadows for negative tidal charges and charges corresponding to naked singularities q=Q2/M2>1, where Q and M are black hole charge and mass, respectively.

A Stellar Dynamical Mass Measurement of the Supermassive Black Hole in NGC 3258

The Astrophysical Journal
We present a stellar dynamical mass measurement of the supermassive black hole in the elliptical (E1) galaxy NGC 3258. Our findings are based on integral field unit spectroscopy from the Multi Unit Spectroscopic Explorer (MUSE) observations in narrow ...

A photometric method to determine supermassive black hole masses

, 2003
We report the discovery of a strong correlation between the shape of a bulge's light-profile and the mass of its central supermassive black hole (Mbh).

Supermassive black holes : the local supermassive black hole mass function

, 2012
Over recent years there has been an increase of the number of secure supermassive black hole (SMBH) detections. These SMBH measurements have lead astronomers to establish well defined empirical relationships between the SMBH mass and some of the properties of the host galaxy.

Follow the Mass—A Concordance Picture of Tidal Disruption Events

The Astrophysical Journal
Three recent global simulations of tidal disruption events (TDEs) have produced, using different numerical techniques and parameters, very similar pictures of their dynamics.

Charged and magnetized particle motion around a static black hole in the Starobinsky–Bel–Robinson gravity

European Physical Journal C: Particles and Fields
In this work we focus on the effects of Starobinsky–Bel–Robinson (SBR) gravity parameter and external magnetic field on the motion of charged test particles and magnetic dipoles moving around a black hole in the selected gravity theory.
