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…
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…
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…
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…
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…
