90 cepheid candidates nearby NGC 6814
We present a Cepheid-based distance to the nearby Seyfert galaxy NGC6814 from Hubble Space Telescope observations. We obtained F555W and F814W imaging over the course of 12... -
Exploring 6 AGN dusty torus models. II.
This is the second in a series of papers devoted to exploring a set of six dusty models of active galactic nuclei (AGN) with available spectral energy distributions. These... -
Black hole masses of SDSS Seyfert 1 galaxies
Narrow-line Seyfert 1 galaxies (NLS1s) are believed to be powered by the accretion of matter onto low-mass black holes (BHs) in spiral host galaxies with BH masses... -
Space telescope RM project. VIII. NGC5548 HST sp.
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC 5548 obtained with the Hubble Space Telescope during the 6 month reverberation mapping campaign in 2014. Our model... -
SEAMBHs. X. Reverberation mapping campaign compilation
We compiled a sample of 73 active galactic nuclei (AGNs) with reverberation mapping (RM) observations from RM campaigns, including our ongoing campaign of monitoring... -
Lick AGN monitoring project 2011: V band
In Spring 2011, the Lick AGN Monitoring Project observed a sample of 15 bright, nearby Seyfert 1 galaxies in the V band as part of a reverberation mapping campaign. The... -
Swift optical & UV flux of four AGNs
Swift intensive accretion disk reverberation mapping of four AGN yielded light curves sampled ~200-350 times in 0.3-10keV X-ray and six UV/optical bands. Uniform reduction and... -
MIR view of polar dust emission in local AGNs
Recent mid-infrared (MIR) interferometric observations have shown that in a few active galactic nuclei (AGNs) the bulk of the infrared emission originates from the polar region... -
Broad H{beta} emission line in 102 Seyfert galaxies
A sample of 102 local (0.02=<z=<0.1) Seyfert galaxies with black hole masses M_BH_>10^7^M_{sun} was selected from the Sloan Digital Sky Survey (SDSS) and observed using... -
The M_BH_-{sigma} relation for active galaxies
We create a baseline of the black hole (BH) mass (M_BH_)-stellar-velocity dispersion ({sigma}) relation for active galaxies, using a sample of 66 local (0.02<z<0.09)... -
3.6um, 4.5um, B and V light curves of NGC 6418
We present results from a 15 month campaign of high-cadence (~3 days) mid-infrared Spitzer and optical (B and V) monitoring of the Seyfert 1 galaxy NGC 6418, with the objective... -
1H 0323+342 rest frame optical spectrum with GHAO
We present optical and near-infrared (NIR) imaging data of the radio-loud, narrow-line Seyfert 1 galaxy 1H 0323+342, which shows intense and variable gamma-ray activity... -
Reverberation mapping of the Seyfert 1 NGC 7469
A large reverberation-mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for H{beta} {lambda}4861 and He II {lambda}4686 and a central black hole mass... -
LOFAR Bootes and 3C295 field sources
We present Low Frequency Array (LOFAR) Low Band observations of the Bootes and 3C 295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy/beam,... -
MIR-selected quasar parameters
We provide a catalog of 391 mid-infrared-selected (MIR; 24 {mu}m) broad-emission-line (BEL; type 1) quasars in the 22 deg^2^ SWIRE Lockman Hole field. This quasar sample is... -
X-ray through NIR photometry of NGC 2617
After the All-Sky Automated Survey for SuperNovae discovered a significant brightening of the inner region of NGC 2617, we began a ~70 day photometric and spectroscopic... -
17 Seyfert 1 galaxies light curves
We present the results of a dust reverberation survey for 17 nearby Seyfert 1 galaxies, which provides the largest homogeneous data collection for the radius of the innermost... -
IRTF J-band spectrum of Mrk 231
We present the first J-band spectrum of Mrk 231, which reveals a large He I {lambda}10830 broad absorption line with a profile similar to that of the well-known Na I broad... -
SEAMBHs. I. Mrk 142, Mrk 335, and IRAS F12397+3333
