AGN STORM 2: I. First results: A Change in the Weather of Mrk 817

Erin Kara, Missagh Mehdipour, Gerard A. Kriss +69

We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for it…

Supermassive black holes with high accretion rates in active galactic nuclei. XI. Accretion disk reverberation mapping of Mrk 142

Edward M. Cackett, Jonathan Gelbord, Yan-Rong Li +15

We performed an intensive accretion disk reverberation mapping campaign on the high accretion rate active galactic nucleus Mrk 142 in early 2019. Mrk 142 was monitored with the Nei…

On the relation between hard X-ray photon index versus accretion rate for super-Eddington accreting quasars

Jian Huang, Bin Luo, Pu Du +3

We investigate whether the hard X-ray photon index () versus accretion rate correlation for super-Eddington accreting quasars is different from that for sub-Eddington accreting…

A Possible ~20 yr Periodicity in Long-term Optical Photometric and Spectral Variations of the Nearby Radio-Quiet Active Galactic Nucleus Ark 120

Yan-Rong Li, Jian-Min Wang, Zhi-Xiang Zhang +15

We study the long-term variability in the optical monitoring database of Ark~120, a nearby radio-quiet active galactic nucleus (AGN) at a distance of 143 Mpc (z=0.03271). We compil…

Optical Spectroscopy of Four Young Radio Sources

Xu-Liang Fan, Jin-Ming Bai, Chen Hu +1

We report the optical spectroscopy of four young radio sources which are observed with the Lijiang 2.4m telescope. The Eddington ratios of these sources are similar with those of n…

A New Approach to Constrain Black Hole Spins in Active Galaxies Using Optical Reverberation Mapping

Jian-Min Wang, Pu Du, Yan-Rong Li +3

A tight relation between the size of the broad-line region (BLR) and optical luminosity has been established in about 50 active galactic nuclei studied through reverberation mappin…
