We have investigated the observational characteristics of a class of broad emission line region (BLR) geometries that connect the outer accretion disc with the inner edge of the dusty toroidal obscuring region (TOR). We suggest that the BLR consists of photoionised gas of densities which allow for efficient cooling by UV/optical emission lines and of incident continuum fluxes which discourage the formation of grains, and that such gas occupies the range of distance and scale height between the… 

Intermediate-line Emission in AGNs: The Effect of Prescription of the Gas Density

The requirement of an intermediate-line component in the recently observed spectra of several active galactic nuclei (AGNs) points to the possible existence of a physically separate region between

Spatially resolved rotation of the broad-line region of a quasar at sub-parsec scale

High-angular-resolution observations of the quasar 3C 273 reveal that it has a relatively small but thick disk, viewed nearly face-on, in which material is orbiting the central supermassive black hole, and support the methods that are often used to estimate the masses of accretingsupermassive black holes and to study their evolution over cosmic time.

Constraints on the outer radius of the broad emission line region of active galactic nuclei.

Here we present observational evidence that the broad emission line region (BELR) of active galactic nuclei (AGN) generally has an outer boundary. This was already clear for sources with an obvious

Stratified disc wind models for the AGN broad-line region: ultraviolet, optical, and X-ray properties

The origin, geometry, and kinematics of the broad-line region (BLR) gas in quasars and active galactic nuclei (AGN) are uncertain. We demonstrate that clumpy biconical disc winds illuminated by an

Accretion disk wind as explanation for the broad-line region structure in NGC 5548

Supermassive black holes in the centers of active galactic nuclei (AGN) are surrounded by broad-line regions (BLRs). The broad emission lines seen in the AGN spectra are emitted in this spatially

Tidally disrupted dusty clumps as the origin of broad emission lines in active galactic nuclei

Type 1 active galactic nuclei display broad emission lines, which are regarded as arising from photoionized gas moving in the gravitational potential of a supermassive black hole1,2. However, the

Failed Radiatively Accelerated Dusty Outflow Model of the Broad Line Region in Active Galactic Nuclei. I. Analytical Solution

The physical origin of the broad line region in active galactic nuclei is still unclear despite many years of observational studies. The reason is that the region is unresolved, and the reverberation

CONSTRAINING UV CONTINUUM SLOPES OF ACTIVE GALACTIC NUCLEI WITH Cloudy MODELS OF BROAD-LINE REGION EXTREME-ULTRAVIOLET EMISSION LINES

Understanding the composition and structure of the broad-line region (BLR) of active galactic nuclei (AGNs) is important for answering many outstanding questions in supermassive black hole evolution,

Nature of quasar disk-wind

The brightest persistent astrophysical sources in the universe are quasars, a group of active galactic nuclei (AGN) that appear star-like and radiate across all wavelengths. The emitted radiation is

Vertical broad-line region structure in nearby active galactic nuclei

Context. Broad emission lines are emitted in the surroundings of supermassive black holes in the centers of active galactic nuclei (AGN). This region is spatially not resolved. Aims. We intend to get

Broad-line active galactic nuclei rotate faster than narrow-line ones

A fundamental relation is reported between the observed emission linewidth full-width at half-maximum (FWHM) and the emission line shape FWHM/σline in AGN spectra that infer that the predominant motion in the broad-line regions is Keplerian rotation in combination with turbulence.
