Nucleosynthesis Contribution of Neutrino-dominated Accretion Flows to the Chemical Evolution of Active Galactic Nuclei
Yan-Qing Qi, Tong Liu, Zhen-Yi Cai +1
Recent observations of quasars show high line-flux ratios in their broad emission lines and the ratios appear to be independent of redshift up to , which indicate that…
Faint AGNs Favor Unexpectedly Long Inter-band Time Lags
Ting Li, Mouyuan Sun, Xiaoyu Xu +12
Inconsistent conclusions are obtained from recent active galactic nuclei (AGNs) accretion disk inter-band time-lag measurements. While some works show that the measured time lags a…
Corona-Heated Accretion-disk Reprocessing (CHAR): A Physical Model to Decipher the Melody of AGN UV/optical Twinkling
Mouyuan Sun, Yongquan Xue, W. N. Brandt +7
Active galactic nuclei (AGNs) have long been observed to "twinkle" (i.e., their brightness varies with time) on timescales from days to years in the UV/optical bands. Such AGN UV/o…
Evolution of quasar stochastic variability along its main sequence
Mouyuan Sun, Yongquan Xue, Junxian Wang +2
We explore the evolution of the time variability (in the optical -band and on timescales of weeks to years) of SDSS Stripe 82 quasars along the quasar main sequence. A parent sa…
A falling Corona model for the anomalous behavior of the broad emission lines in NGC 5548
Mouyuan Sun, Yongquan Xue, Zhenyi Cai +1
NGC 5548 has been intensively monitored by the AGN Space Telescope and Optical Reverberation Mapping collaboration. Approximately after half of the light curves, the correlation be…
