The broad emission-line region: the confluence of the outer accretion disc with the inner edge of the dusty torus
M. R. Goad, K. T. Korista, A. J. Ruff
(Abridged) We investigate the observational characteristics of BLR geometries in which the BLR clouds bridge the gap, both in distance and scale height, between the outer accretion…
New Constraints on the Quasar Broad Emission Line Region
Andrea J. Ruff, David J. E. Floyd, Rachel L. Webster +2
We demonstrate a new technique for determining the physical conditions of the broad line emitting gas in quasars, using near-infrared hydrogen emission lines. Unlike higher ionisat…
The SL2S Galaxy-scale Gravitational Lens Sample. I. The alignment of mass and light in massive early-type galaxies at z=0.2-0.9
Raphael Gavazzi, Tommaso Treu, Philip J. Marshall +2
We study the relative alignment of mass and light in a sample of 16 massive early-type galaxies at z=0.2-0.9 that act as strong gravitational lenses. The sample was identified from…
The SL2S Galaxy-scale Lens Sample. II. Cosmic evolution of dark and luminous mass in early-type galaxies
Andrea J. Ruff, Raphael Gavazzi, Philip J. Marshall +3
We present a joint gravitational lensing and stellar-dynamical analysis of 11 early-type galaxies (median deflector redshift $\zd=0.5$) from Strong Lenses in the Legacy Survey (SL2…
A Quasar Wind Model
Andrea Ruff
A quasar wind model is proposed to describe the spatial and velocity structure of the broad line region. This model requires detailed photoionization and magnetohydrodynamic simula…
