Mass Functions of Supermassive Black Holes across Cosmic Time [PDF]
Advances in Astronomy, 2012 The black hole mass function of supermassive black holes describes the evolution of the distribution of black hole mass. It is one of the primary empirical tools available for mapping the growth of supermassive black holes and for constraining ...

A supermassive black hole in an ultra-compact dwarf galaxy
Nature, 2014 Ultracompact dwarf galaxies (UCDs) are among the densest stellar systems in the universe. These systems have masses up to 200 million solar masses, but half light radii of just 3-50 parsecs.

Investigation of some galactic and extragalactic gravitational phenomena [PDF]
Serbian Astronomical Journal, 2012 Here we present a short overview of the most important results of our investigations of the following galactic and extragalactic gravitational phenomena: supermassive black holes in centers of galaxies and quasars, supermassive black hole ...

Supermassive black holes and their environments [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 We make use of the first high--resolution hydrodynamic simulations of structure formation which self-consistently follows the build up of supermassive black holes introduced in Di Matteo et al. (2007) to investigate the relation between black holes (BH), host halo and large--scale environment.

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}_{-

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 (

On the Formation and Interaction of Multiple Supermassive Stars in Cosmological Flows
The Astrophysical Journal, 2023 Supermassive primordial stars with masses exceeding ∼10 ^5 M _⊙ that form in atomically cooled halos are the leading candidates for the origin of high-redshift quasars at z > 6.

Supermassive black holes in BCGs [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe observed a sample of three Brightest Cluster Galaxies (BCGs), Abell 1836-BCG, Abell 2052-BCG, and Abell 3565-BCG, with the Advanced Camera for Surveys (ACS) and the Imaging Spectrograph (STIS) on board the Space Telescope. For each target galaxy we obtained high-resolution spectroscopy of the Hα and [N II] λ6583 emission lines at three slit ...
