Quantum Aspects of Black Holes [PDF]

open access: yes, 2006
In this thesis we study two quantum aspects of black holes, their entropy and the Hawking effect. First, we present a model for the statistical interpretation of black hole entropy and show that this entropy emerges as a result of missing information ...

Probing the Mass Relation between Supermassive Black Holes and Dark Matter Halos at High Redshifts by Gravitational Wave Experiments

open access: yesThe Astrophysical Journal, 2023
Numerous observations have shown that almost all galaxies in our Universe host supermassive black holes (SMBHs), but there is still much debate about their formation and evolutionary processes. Recently, gravitational waves (GWs) have been expected to be

The Dynamics of White Dwarfs, Black Holes and Stellar Cusps [PDF]

open access: yes, 2013
This thesis contains topics related mostly to the dynamics of white dwarfs (chapter 2), the dynamics of stars around binary super massive black holes (chapters 4, 5 and 6) and dynamics in the singular isothermal sphere (chapter 7).

Global Understanding of Accretion and Ejection around Black Holes

open access: yesGalaxies, 2022
Accretion and ejection around compact objects, mainly around black holes, both in low mass, and supermassive, is rich and has been studied exhaustively [...]

No Supermassive Black Hole in M33?

open access: yesScience, 2001
We observed the nucleus of M33, the third-brightest galaxy in the Local Group, with the Space Telescope Imaging Spectrograph at a resolution at least a factor of 10 higher than previously obtained. Rather than the steep rise expected within the radius of gravitational influence of a supermassive black hole, the random stellar velocities showed a ...

A Candidate Runaway Supermassive Black Hole Identified by Shocks and Star Formation in its Wake

open access: yesThe Astrophysical Journal Letters, 2023
The interaction of a runaway supermassive black hole (SMBH) with the circumgalactic medium (CGM) can lead to the formation of a wake of shocked gas and young stars behind it.

THE SUPERMASSIVE BLACK HOLE IN M84 REVISITED [PDF]

open access: yesThe Astrophysical Journal, 2010
The mass of the central black hole in the giant elliptical galaxy M84 has previously been measured by two groups using the same observations of emission-line gas with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope, giving strongly discrepant results: Bower et al. (1998) found M_BH = (1.5^{+1.1}_{-0.6}) x 10^9 M_sun, while

Leptonic and Hadronic Radiative Processes in Supermassive-Black-Hole Jets

open access: yesGalaxies, 2020
Supermassive black holes lying in the center of galaxies can launch relativistic jets of plasma along their polar axis. The physics of black-hole jets is a very active research topic in astrophysics, owing to the fact that many questions remain open on ...

A NEARLY NAKED SUPERMASSIVE BLACK HOLE [PDF]

open access: yesThe Astrophysical Journal, 2017
ABSTRACT During a systematic search for supermassive black holes (SMBHs) not in galactic nuclei, we identified the compact, symmetric radio source B3 1715+425 with an emission-line galaxy offset ≈ 8.5
