Tidally disrupted dusty clumps as the origin of broad emission lines in active galactic nuclei
Jian-Min Wang, Pu Du, Michael S. Brotherton +5
Type 1 active galactic nuclei display broad emission lines, regarded as arising from photoionized gas moving in the gravitational potential of a supermassive black hole. The origin…
Self-consistent dynamical model of the Broad Line Region
Bozena Czerny, Yan-Rong Li, Justyna Sredzinska +4
We develope a self-consistent description of the Broad Line Region based on the concept of the failed wind powered by the radiation pressure acting on dusty accretion disk atmosphe…
Failed radiatively Accelerated Dusty Outflow model of the Broad Line Region in Active Galactic Nuclei. I. Analytical solution
B. Czerny, Yan-Rong Li, K. Hryniewicz +6
The physical origin of the Broad Line Region in Active Galactic Nuclei is still unclear despite many years of observational studies. The reason is that the region is unresolved and…
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…
