The many lives of active galactic nuclei: cooling flows, black holes and the luminosities and colour [PDF]

open access: yes, 2005
We simulate the growth of galaxies and their central supermassive black holes by implementing a suite of semi-analytic models on the output of the Millennium Run, a very large simulation of the concordance A cold dark matter cosmogony.

Black holes, gravitational waves and fundamental physics: a roadmap [PDF]

open access: yesClassical and quantum gravity, 2018
The grand challenges of contemporary fundamental physics—dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem—all involve gravity as a key component.

Thermodynamics of Born-Infeld-anti-de Sitter black holes in the grand canonical ensemble [PDF]

open access: yes, 2006
The main objective of this paper is to study thermodynamics and stability of static electrically charged Born-Infeld black holes in AdS space in D=4. The Euclidean action for the grand canonical ensemble is computed with the appropriate boundary terms ...

Hairy black holes of Lovelock–Born–Infeld-scalar gravity

open access: yesPhysics Letters B, 2018
In this paper we construct new hairy black holes of Lovelock–Born–Infeld-scalar gravity in diverse dimensions. We study horizon structures of the black holes and find the black holes may possess three horizons, two horizons or one horizon.

Rotating black holes in 4D Einstein-Gauss-Bonnet gravity and its shadow

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
Recently there has been a surge of interest in regularizing, a D → 4 limit of, the Einstein-Gauss-Bonnet (EGB) gravity, and the resulting regularized 4D EGB gravity has nontrivial dynamics. The theory admits spherically symmetric black holes generalizing

The Assembly of the First Massive Black Holes [PDF]

open access: yes, 2019
The existence of $\approx$10^9 Msun supermassive black holes (SMBHs) within the first billion year of the universe has stimulated numerous ideas for the prompt formation and rapid growth of BHs in the early universe.

Origin of Correlations between Central Black Holes Masses and Galactic Bulge Velocity Dispersions [PDF]

open access: yes, 2002
We argue that the observed correlations between central black holes masses M_{BH} and galactic bulge velocity dispersions \sigma_e in the form M_{BH}\propto\sigma_e^4 may witness on the pregalactic origin of massive black holes.

Black hole cannibalism [PDF]

open access: yesInternational Journal of Modern Physics D, 2021
In this paper, we consider a version of the Hayden–Preskill thought experiment in which the message thrown into the black hole is itself a smaller black hole. We then discuss the implications of the existence of a recovery channel for this black hole message at asymptotic infinity, resulting in a sharpening of the black hole information paradox for ...

Martin Heidegger and the Being and Time of Black Holes [PDF]

open access: yesФилософия и космология, 2020
Scientific narratives about cosmology often present black holes as frightening objects of both creation and destruction, the centres of which are concealed behind event horizons.
