Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XII. Reverberation Mapping Results for 15 PG Quasars from a Long-Duration High-Cadence Campaign
Chen Hu, Sha-Sha Li, Sen Yang +15
We present the first results from long-term high-cadence spectroscopic monitoring of 15 PG quasars with relatively strong Fe II emission as a part of a broader reverberation mappin…
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…
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…
The outburst of the changing-look AGN IRAS23226-3843 in 2019
Wolfram Kollatschny, Dirk Grupe, Michael L. Parker +8
IRAS23226-3843 has previously been classified as a changing-look AGN based on X-ray and optical spectral variations. In 2019, Swift observations revealed a strong rebrightening in…
Monitoring AGNs with H Asymmetry. III. Long-term Reverberation Mapping Results of 15 Palomar-Green Quasars
Dong-Wei Bao, Michael S. Brotherton, Pu Du +42
In this third paper of the series reporting on the reverberation mapping (RM) campaign of active galactic nuclei with asymmetric H emission-line profiles, we present results for…
A revised simplified scattering model for the moonlit sky brightness profile based on photometry at SAAO
Hartmut Winkler
This paper presents multi-filter measurements of the night sky brightness at the South African Astronomical Observatory (SAAO) in Sutherland in the presence of a bright moon. The o…
