Supermassive black hole ancestors [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2012
We study a model in which supermassive black holes (SMBHs) can grow by the combined action of gas accretion on heavy seeds and mergers of both heavy (m_s^h=10^5 Msol) and light (m_s^l = 10^2 Msol) seeds.

Formation of supermassive black hole seeds [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2016
The detection of quasars at $z>6$ unveils the presence of supermassive black holes (BHs) of a few billion solar masses. The rapid formation process of these extreme objects remains a fascinating and open issue.

Supermassive Black Hole Feedback

open access: yes, 2019
Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern astrophysics. We now know that the evolution of galaxies is critically shaped

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 ...

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.

Visible Shapes of Black Holes M87* and SgrA*

open access: yesUniverse, 2020
We review the physical origins for possible visible images of the supermassive black hole M87* in the galaxy M87 and SgrA* in the Milky Way Galaxy. The classical dark black hole shadow of the maximal size is visible in the case of luminous background ...

The Brightest Point in Accretion Disk and Black Hole Spin: Implication to the Image of Black Hole M87*

open access: yesUniverse, 2019
We propose the simple new method for extracting the value of the black hole spin from the direct high-resolution image of black hole by using a thin accretion disk model.
