We analyze the broadband photometric light curves of Seyfert 1 galaxies from the Sergeev et al. sample and find that (1) perturbations propagating across the continuum emitting region are a general phenomenon securely detected in most cases, (2) it is possible to obtain reliable time delays between continuum emission in different wavebands, which are not biased by the contribution of broad emission lines to the signal, and (3) such lags are consistent with the predictions of standard irradiated…

Direct evidence of non-disk optical continuum emission around an active black hole
Accretion onto black holes is key to their growth over cosmic time1, especially during the active galactic nuclei phase when the inflowing material forms a radiatively efficient accretion disk2. To
An accretion disc-irradiation hybrid model for the optical/UV variability in radio-quiet quasars
The optical/ultraviolet (UV) variability of quasars has been discovered to be correlated with other quasar properties, such as luminosity, black hole mass and rest-frame wavelength. However,the
Constraints on the temperature inhomogeneity in quasar accretion discs from the ultraviolet-optical spectral variability
The physical mechanisms of the quasar ultraviolet (UV)-optical variability are not well understood despite the long history of observations. Recently, Dexter & Agol presented a model of quasar
Ultraviolet variability of quasars: dependence on the accretion rate
Aims. Although the variability in the ultraviolet and optical domain is one of the major characteristics of quasars, the dominant underlying mechanisms are still poorly understood. There is a broad
Radiative efficiency of disc accretion in individual SDSS QSOs
We estimate the radiative efficiencyǫ of individual type 1 SDSS QSOs by using their bolometric luminosities (Lbol) and accretion rates ( u M•,acc), which may be related to the assembly histories and
Accretion disk reverberation with Hubble Space Telescope observations of NGC 4593: evidence for diffuse continuum lags
The Seyfert 1 galaxy NGC 4593 was monitored spectroscopically with the Hubble Space Telescope as part of a reverberation mapping campaign that also included Swift, Kepler and ground-based photometric
Origin and properties of dual and offset active galactic nuclei in a cosmological simulation at z=2
In the last few years, it became possible to observationally resolve galaxies with two distinct nuclei in their centre. For separations smaller than 10 kpc, dual and offset active galactic nuclei
New mechanism of radiation polarization in type 1 Seyfert active galactic nuclei
In most of Seyfert-1 active galactic nucei (AGN) the optical linear continuum polarization degree is usually small (less than 1%) and the polarization position angle is nearly parallel to the AGN
A refined sub-grid model for black hole accretion and AGN feedback in large cosmological simulations
In large scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion onto black holes and AGN feedback are commonly used. Such models typically depend on various free
Modelling photometric reverberation data: a disk-like broad-line region and a potentially larger black hole mass for 3C 120
We consider photometric reverberation mapping, where the nuclear continuum variations are monitored via a broad-band filter and the echo of emission line clouds of the broad-line region (BLR) is


The radiative efficiency of AGN is commonly estimated based on the total mass accreted and the total AGN light emitted per unit volume in the universe integrated over time (the Soltan argument). In
Can we measure the accretion efficiency of active galactic nuclei
The accretion efficiency for individual black holes is very difficult to determine accurately. There are many factors that can influence each step of the calculation, such as the dust and host galaxy
The ultraviolet excess of luminous quasars. II: Evidence for massive accretion disks
This paper presents new infrared, optical, and ultraviolet spectra of three high-redshift quasars. They are analyzed along with three published quasar spectra. After accounting for other sources of
Testing thermal reprocessing in active galactic nuclei accretion discs
The thermal reprocessing hypothesis in active galactic nuclei (AGN), where extreme ultraviolet/X-ray photons are reprocessed by the accretion disc into optical/UV photons, predicts
Are quasars accreting at super-Eddington rates?
In a previous paper, Collin & Hur e (2001), using a sample of Active Galactic Nuclei (AGN) where the mass has been determined by reverberation studies (the Kaspi et al. 2000 sample), have shown that
Reverberation Measurements for 17 Quasars and the Size-Mass-Luminosity Relations in Active Galactic Nuclei
Correlated variations in the line and continuum emission from active galactic nuclei (AGNs) can be used to determine the size and geometry of the broad emission-line regions (BLRs). We have spectro-
Sizes and Temperature Profiles of Quasar Accretion Disks from Chromatic Microlensing
Microlensing perturbations to the flux ratios of gravitationally lensed quasar images can vary with wavelength because of the chromatic dependence of the accretion disk's apparent size.
The Quasar Accretion Disk Size-Black Hole Mass Relation
We use the microlensing variability observed for 11 gravitationally lensed quasars to show that the accretion disk size at a rest-frame wavelength of 2500 A is related to the black hole mass by log(R
Constraining the accretion rate onto Sagittarius A * using linear polarization
Two possible explanations for the low luminosity of the supermassive black hole at the center of our Galaxy are (1) an accretion rate of the order of the canonical Bondi value (~10-5 M? yr-1) but a
Quasar Accretion Disks are Strongly Inhomogeneous
Active galactic nuclei have been observed to vary stochastically with 10%-20% rms amplitudes over a range of optical wavelengths where the emission arises in an accretion disk. Since the accretion
