Black hole mass estimate for a sample of radio-loud narrow-line Seyfert 1 galaxies
We discuss the relationship between a standard Shakura & Sunyaev (1973) accretion disk model and the Big Blue Bump (BBB) observed in Type 1 AGN, and propose a new method to estimate black holeExpand

Super-Critical Growth of Massive Black Holes from Stellar-Mass Seeds
We consider super-critical accretion with angular momentum onto stellar-mass black holes as a possible mechanism for growing billion-solar-mass black holes from light seeds at early times. We use theExpand

Observability of Dual Active Galactic Nuclei in Merging Galaxies
Supermassive black holes (SMBHs) have been detected in the centers of most nearby massive galaxies. Galaxies today are not only the products of billions of years of galaxy mergers, but also billionsExpand

Gravitational recoil from accretion-aligned black-hole binaries
We explore the newly discovered "hangup-kick" effect, which greatly amplifies the recoil for configuration with partial spin- orbital-angular momentum alignment, by studying a set of 48 newExpand

Limiting eccentricity of subparsec massive black hole binaries surrounded by self-gravitating gas discs
We study the dynamics of supermassive black hole binaries embedded in circumbinary gaseous discs, with the SPH code GADGET-2. The sub-parsec binary (of total mass M and mass ratio q = 1/3) hasExpand

SDSSJ092712.65+294344.0: a candidate massive black hole binary
In this Letter, we explore the hypothesis that the quasar SDSSJ092712.65+294344.0 is hosting a massive black hole binary embedded in a circumbinary disc. The lightest, secondary black hole is active,Expand

Hα3: an Hα imaging survey of HI selected galaxies from ALFALFA - VI. The role of bars in quenching star formation from z = 3 to the present epoch
A growing body of evidence indicates that the star formation rate per unit stellar mass (sSFR) decreases with increasing mass in normal main-sequence star-forming galaxies. Many processes have beenExpand

Mass and spin co-evolution during the alignment of a black hole in a warped accretion disc
In this paper, we explore the gravitomagnetic interaction of a black hole (BH) with a misaligned accretion disc to study BH spin precession and alignment jointly with BH mass M BH and spin parameterExpand

Evolution of binary black holes in self gravitating discs. Dissecting the torques
Context. Massive black hole binaries, formed in galaxy mergers, are expected to evolve in dense circumbinary discs. Understanding of the disc-binary coupled dynamics is vital to assess both t heExpand
