Detailed line profile variability studies of the narrow line Seyfert 1 galaxy Mrk 110 are presented. We obtained the spectra in a variability campaign carried out with the 9.2 m Hobby-Eberly Telescope at McDonald Observatory. The integrated Balmer and helium (He i, ii) emission lines are delayed by 3 to 33 light days to the optical continuum variations respectively. The outer wings of the line profiles respond much faster to continuum variations than the central regions. The comparison of the… 
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
Broad-line active galactic nuclei rotate faster than narrow-line ones
TLDR
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.
Broad-line region structure and kinematics in the radio galaxy 3C 120
Broad emission lines originate in the surroundings of supermassive black holes in the centers of active galactic nuclei (AGN). One method to investigate the extent, structure, and kinematics of the
Line profile variations in selected Seyfert galaxies
Continua as well as the broad emission lines in Seyfert 1 galaxies vary in different galaxies with different amplitudes on typical timescales of days to years. We present the results of two
EFFECTS OF AN ACCRETION DISK WIND ON THE PROFILE OF THE BALMER EMISSION LINES FROM ACTIVE GALACTIC NUCLEI
We explore the connection between active galactic nuclei (AGNs) with single- and double-peaked broad Balmer emission lines by using models dealing with radiative transfer effects through a disk wind.
Contribution of a Disk Component to Single Peaked Broad Lines of Active Galactic Nuclei
We study the disk emission component hidden in the single-peaked Broad Emission Lines (BELs) of Active Galactic Nuclei (AGN). We compare the observed broad lines from a sample of 90 Seyfert 1 spectra
Contribution of the disk emission to the broad emission lines in AGNs: Two-component model
We present an investigation of the structure of the emission line region in a sample of 12 single-peaked Active Galactic Nuclei (AGNs). Using the high resolution Hβ and Hα line profiles observed with
CENTRAL MASSES AND BROAD-LINE REGION SIZES OF ACTIVE GALACTIC NUCLEI. II. A HOMOGENEOUS ANALYSIS OF A LARGE REVERBERATION-MAPPING DATABASE
We present improved black hole masses for 35 active galactic nuclei (AGNs) based on a complete and consistent reanalysis of broad emission-line reverberation-mapping data. From objects with multiple
Strong Response of the Very Broad Hβ Emission Line in the Luminous Radio-quiet Quasar PG 1416-129
We report new spectroscopic observations performed in 2010 and 2011 for the luminous radio-quiet quasar PG 1416-129. Our new spectra with high quality cover both H{beta} and H{alpha} regions, and
The case for inflow of the broad-line region of active galactic nuclei
The high-ionization lines of the broad-line region (BLR) of thermal active galactic nuclei (AGNs) show blueshifts of a few hundred km/s to several thousand km/sec with respect to the low-ionization

Disk Winds and Disk Emission Lines
We show that a thin disk illuminated by a central source will produce single-peaked broad emission lines if there is a wind emerging from the disk. Line-driven winds in active galactic nuclei and in
Short-term emission line and continuum variations in Mrk 110
We present results of a variability campaign of Mrk 110 performed with the 9.2-m Hobby-Eberly Telescope (HET) at McDonald Observatory. The high $S/N$ spectra cover most of the optical range. They
Reverberation mapping and the disk wind model of the broad line region
Using the disk wind model of Murray et al. (1995), we calculate line profiles and frequency-resolved response functions for broad line emission from the surface of an accretion disk in an AGN in the

We recorded spectra of the highly variable Seyfert 1 galaxy Mrk 110 in a variability campaign with the 9.2 m Hobby-Eberly Telescope at McDonald Observatory in order to study the detailed line prole
Dynamics of broad emission-line region in NGC 5548: Hydromagnetic wind model versus observations
We analyze the results of long-term observations of the broad-line region (BLR) in the Seyfert 1 galaxy NGC 5548 and provide a critical comparison with the predictions of a hydromagnetically driven

Dynamics of Line-driven Disk Winds in Active Galactic Nuclei
We present the results of axisymmetric time-dependent hydrodynamic calculations of line-driven winds from accretion disks in active galactic nuclei (AGNs). We assume the disk is flat, Keplerian,

This paper proposes a simple, empirically derived, unifying structure for the inner regions of quasars. This structure is constructed to explain the broad absorption line regions (BALRs) and the

Centrifugally driven winds from the surfaces of magnetized accretion disks have been recognized as an attractive mechanism of removing the angular momentum of the accreted matter and of producing the
