The Host Galaxy Fluxes of Active Galaxy Nuclei Are Generally Overestimated by the Flux Variation Gradient Method
Minxuan Cai, Zhen Wan, Zhenyi Cai +2
In terms of the variable nature of normal active galaxy nuclei (AGN) and luminous quasars, a so-called flux variation gradient (FVG) method has been widely utilized to estimate the…
Sciences with the 2.5-meter Wide Field Survey Telescope (WFST)
WFST Collaboration, Tinggui Wang, Guilin Liu +60
The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying facility being built jointly by the University of Science and Technology of China and the Purple Mountai…
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…
Interpreting the statistical properties of high-z extragalactic sources detected by the South Pole Telescope survey
Zhen-Yi Cai, Mattia Negrello, Gianfranco De Zotti
The results of the recently published spectroscopically complete survey of dusty star-forming galaxies detected by the South Pole Telescope (SPT) over 2500 deg^2 proved to be chall…
Extreme Variability Quasars in Their Various States. I: The sample selection and composite SDSS spectra
Wenke Ren, Junxian Wang, Zhenyi Cai +1
Extremely variable quasars (EVQs) are a population of sources showing large optical photometric variability revealed by time-domain surveys. The physical origin of such extreme var…
The effect of the morphological quenching mechanism on star formation activity at 0.5 < z < 1.5 in 3D-HST/CANDELS
Shiying Lu, Guanwen Fang, Yizhou Gu +3
Several mechanisms for the transformation of blue star-forming to red quiescent galaxies have been proposed, and the green valley (GV) galaxies amid them are widely accepted in a t…
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…
An Extraordinary Response of Iron Emission to the Central Outburst in a Tidal Disruption Event Candidate
Zhicheng He, Ning Jiang, Tinggui Wang +9
Understanding the origin of \feii\ emission is important because it is crucial to construct the main sequence of Active Galactic Nuclei (AGNs). Despite several decades of observati…
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…
The mass dependence of structure, star formation rate, and mass assembly mode at 0.5<z< 2.5
Yizhou Gu, Guanwen Fang, Qirong Yuan +5
To investigate the mass dependence of structural transformation and star formation quenching, we construct three galaxy samples using massive () red, green…
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…
The morphological evolution, AGN fractions, dust content, environments, and downsizing of massive green valley galaxies at 0.5<z<2.5 in 3D-HST/CANDELS
Yizhou Gu, Guanwen Fang, Qirong Yuan +2
To explore the evolutionary connection among red, green, and blue galaxy populations, based on a sample of massive () galaxies at 0.5<z<2.5 in five 3D-HST…
Predictions for surveys with the SPICA Mid-infrared Instrument
M. Bonato, M. Negrello, Z. -Y. Cai +8
We present predictions for number counts and redshift distributions of galaxies detectable in continuum and in emission lines with the Mid-infrared (MIR) Instrument (SMI) proposed…
Radio Observations of Star Forming Galaxies in the SKA era
C. Mancuso, A. Lapi, Z-Y. Cai +4
We have combined determinations of the epoch-dependent star formation rate (SFR) function with relationships between SFR and radio (synchrotron and free-free) emission to work out…
