Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XIII. Ultraviolet Time Lag of H Emission in Mrk 142
V. C. Khatu, S. C. Gallagher, K. Horne +17
We performed a rigorous reverberation-mapping analysis of the broad-line region (BLR) in a highly accreting () active galactic nucleus, Markarian 142 (…
AGN STORM 2: V. Anomalous Behavior of the CIV Light Curve in Mrk 817
Y. Homayouni, Gerard A. Kriss, Gisella De Rosa +49
An intensive reverberation mapping campaign on the Seyfert 1 galaxy Mrk817 using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) revealed significant vari…
Continuum Reverberation Mapping of Mrk 876 Over Three Years With Remote Robotic Observatories
Jake A. Miller, Edward M. Cackett, Michael R. Goad +9
Continuum reverberation mapping probes the sizescale of the optical continuum-emitting region in active galactic nuclei (AGN). Through 3 years of multiwavelength photometric monito…
AGN STORM 2: II. Ultraviolet Observations of Mrk817 with the Cosmic Origins Spectrograph on the Hubble Space Telescope
Y. Homayouni, Gisella De Rosa, Rachel Plesha +62
We present reverberation mapping measurements for the prominent ultraviolet broad emission lines of the active galactic nucleus Mrk817 using 165 spectra obtained with the Cosmic Or…
A complex dust morphology in the high-luminosity AGN Mrk 876
Hermine Landt, Jake A. J. Mitchell, Martin J. Ward +9
Recent models for the inner structure of active galactic nuclei (AGN) advocate the presence of a radiatively accelerated, dusty outflow launched from the outer regions of the accre…
First detection of the outer edge of an AGN accretion disc: Very fast multiband optical variability of NGC 4395 with GTC/HiPERCAM and LT/IO:O
I. M. McHardy, M. Beard, E. Breedt +11
We present fast (~200s sampling) ugriz photometry of the low mass AGN NGC 4395 with the Liverpool Telescope, followed by very fast (3s sampling) us, gs, rs, is and zs simultaneous…
