Supermassive Black Hole Growth in Hierarchically Merging Nuclear Star Clusters [PDF]

open access: yesThe Astrophysical Journal
Supermassive black holes are prevalent at the centers of massive galaxies, and their masses scale with galaxy properties, increasing evidence suggesting that these trends continue to low stellar masses.

Evidence for supermassive black hole binaries [PDF]

open access: yesPublications of the Astronomical Society of Australia
Abstract We review the state of the evidence for the existence and observational appearance of supermassive black hole binaries. Such objects are expected from standard hierarchical galaxy evolution to form after two galaxies, each containing a supermassive black hole, have merged, in the centre of the merger remnant.

Supermassive black holes and their environments [PDF]

open access: yesMonthly 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.

Supermassive black holes in BCGs [PDF]

open access: yesProceedings 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 ...

Growth of Supermassive Black Holes, Galaxy Mergers and Supermassive Binary Black Holes [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
AbstractThe study of galaxy mergers and supermassive binary black holes (SMBBHs) is central to our understanding of the galaxy and black hole assembly and (co-)evolution at the epoch of structure formation and throughout cosmic history. Galaxy mergers are the sites of major accretion episodes, they power quasars, grow supermassive black holes (SMBHs ...

A FUNDAMENTAL EQUATION FOR SUPERMASSIVE BLACK HOLES [PDF]

open access: yesInternational Journal of Modern Physics D, 2011
We developed a theoretical model that is able to give a common origin to the correlations between the mass M• of supermassive black holes and the mass, velocity dispersion, kinetic energy and momentum parameter of the corresponding host galaxies. Our model is essentially based on the transformation of the angular momentum of the interstellar material,

Decomposition of the central structure of NGC 2273 in the NIR: A case study

open access: yesAstronomische Nachrichten, Volume 344, Issue 10, December 2023., 2023
Abstract The Seyfert 2 galaxy NGC 2273 is a prime target to explore how active nuclei can be fed. It has a star‐forming innermost nuclear ring with a radius of 0.33kpc from where material may be funneled to the supermassive black hole in its center. In this article, we discuss high‐resolution adaptive optics aided JHKs images of NGC 2273 taken with the
