Active galactic nuclei at z ∼ 1.5 – III. Accretion discs and black hole spin
(Oxford University Press, 2016)
This is the third paper in a series describing the spectroscopic properties of a sample of 39 AGN at z similar to 1.5, selected to cover a large range in black hole mass (M-BH) and Eddington ratio (L/L-Edd). In this paper, ...
Resolved observations of transition disks
(Cambridge University Press, 2016-04)
Resolved observations are bringing new constraints on the origin of radial gaps in protoplanetary disks. The kinematics, sampled in detail in one case-study, are indicative of non-Keplerian flows, corresponding to warped ...
Precession and accretion in circumbinary discs: the case of HD 104237
(Royal Astronomical Society, 2015)
We present the results of smoothed particle hydrodynamics (SPH) simulations of the disc
around the young, eccentric stellar binary HD 104237. We find that the binary clears out a
large cavity in the disc, driving a ...
Active galactic nuclei at z similar to 1.5-I. Spectral energy distribution and accretion discs
(Oxford University Press, 2015)
The physics of active super massive black holes (BHs) is governed by their mass (MBH), spin (a(*)) , and accretion rate ((M) over dot). This work is the first in a series of papers with the aim of testing how these parameters ...
