Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]

open access: yes, 2006
In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

Supermassive black holes: Coevolution (or not) of black holes and host galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2012
AbstractSupermassive black holes (BHs) have been found in 75 galaxies by observing spatially resolved dynamics. The Hubble Space Telescope (HST) revolutionized BH work by advancing the subject from its ‘proof of concept’ phase into quantitative studies of BH demographics.

Bayesian Black Hole Photogrammetry

open access: yesThe Astrophysical Journal
We propose an analytic dual-cone accretion model for horizon-scale images of the cores of low-luminosity active galactic nuclei, including those observed by the Event Horizon Telescope (EHT).

High-redshift supermassive black holes from tiny black hole explosions [PDF]

open access: yes
Recent observations of the high-redshift universe have uncovered a significant number of active galactic nuclei, implying that supermassive black holes (SMBHs) would have to have been formed at much earlier times than expected.

The cosmological history of accretion onto dark halos and supermassive black holes [PDF]

open access: yes, 2006
Aims: We investigate the cosmological growth of dark halos and follow the consequences of coeval growth for the accretion history of associated supermassive black holes.

Dynamics Around Supermassive Black Holes: Extreme-mass-ratio Inspirals as Gravitational-wave Sources

open access: yesThe Astrophysical Journal
Supermassive black holes and their surrounding dense stellar environments nourish a variety of astrophysical phenomena. We focus on the distribution of stellar-mass black holes around the supermassive black hole and the consequent formation of extreme ...

High-energy signatures of binary supermassive black holes

open access: yesEPJ Web of Conferences, 2013
Some active galactic nuclei are supposed to harbor binary systems of supermassive black holes. They are an attractive target for gravitational wave experiments.
