Powerful jets from accreting black holes: evidence from the optical and infrared

, 2010
A common consequence of accretion onto black holes is the formation of powerful, relativistic jets that escape the system. In the case of supermassive black holes at the centres of galaxies this has been known for decades, but for stellar-mass black ...

A Comparison of the X-Ray Polarimetric Properties of Stellar and Supermassive Black Holes

The Astrophysical Journal
X-ray polarization provides a new way to probe accretion geometry in black hole systems. If the accretion geometry of black holes is similar regardless of mass, we should expect the same to be true of their polarization properties.

Mechanism for the Suppression of Intermediate-Mass Black Holes

, 2010
A model for the formation of supermassive primordial black holes in galactic nuclei with the simultaneous suppression of the formation of intermediate-mass black holes is presented. A bimodal mass function for black holes formed through phase transitions

High-energy signatures of binary supermassive black holes

EPJ 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.

Deeper, Wider, Sharper: Next-Generation Ground-Based Gravitational-Wave Observations of Binary Black Holes [PDF]

, 2019
Next-generation observations will revolutionize our understanding of binary black holes and will detect new sources, such as intermediate-mass black holes.

Probing the formation of the seeds of supermassive black holes with gravitational waves

, 2018
The existence of black holes in the intermediate mass interval between one hundred and ten thousand solar masses, filling the gap between the stellar and the supermassive black holes is a key prediction to explain the origin of luminous QSOs at redshifts

The Millennium Galaxy Catalogue: The nearby supermassive black hole mass function

, 2005
We highlight the correlation between a galaxy's supermassive black hole mass and the Sersic-index of the host spheroid or bulge component. From our bulge-disk decompositions of 10 095 galaxies, drawn from the Millennium Galaxy Catalogue, we construct the
