Final compact remnants in core-collapse supernovae from 20 to 40 : the lower mass gap
Tong Liu, Yun-Feng Wei, Li Xue +1
A mass paucity of compact objects in the range of has been suggested by X-ray binary observations, namely, the "lower mass gap". Gravitational wave detections h…
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…
Modeling Quasar UV/Optical Variability with the Corona-heated Accretion-disk Reprocessing (CHAR) Model
Mouyuan Sun, Yongquan Xue, Hengxiao Guo +7
The rest-frame UV/optical variability of the quasars in the Sloan Digital Sky Survey (SDSS) Stripe 82 is used to test the Corona-Heated Accretion-disk Reprocessing (CHAR) model of…
Piercing through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields. II. Are Highly Obscured AGNs the Missing Link in the Merger-Triggered AGN-Galaxy Coevolution Models?
Junyao Li, Yongquan Xue, Mouyuan Sun +12
By using a large highly obscured () AGN sample (294 sources at ) selected from detailed X-ray spectral analyses in the deepest Chandra…
Neutrino-dominated accretion flows: second nucleosynthesis factory in core-collapse supernovae and regulation of iron markets in galaxies
Tong Liu, Yan-Qing Qi, Zhen-Yi Cai +3
Cosmic metals are widely believed to be produced by supernovae (SNe) and compact object mergers. Here, we discuss the nucleosynthesis of neutrino-dominated accretion flows (NDAFs)…
High-redshift Extreme Variability Quasars from Sloan Digital Sky Survey Multi-Epoch Spectroscopy
Hengxiao Guo, Jiacheng Peng, Kaiwen Zhang +9
We perform a systematic search for high-redshift ( 1.5) extreme variability quasars (EVQs) using repeat spectra from the Sixteenth Data Release of Sloan Digital Sky Survey, wh…
AGNs are not that cool: revisiting the intrinsic AGN far-infrared spectral energy distribution
Jun Xu, Mouyuan Sun, Yongquan Xue
We investigate the intrinsic spectral energy distribution (SED) of active galactic nuclei (AGNs) at infrared (IR) bands with 42 optically luminous Palomar Green survey qu…
EUCLIA. II. On the puzzling large UV to X-ray lags in Seyfert galaxies
Zhen-Yi Cai, Jun-Xian Wang, Mouyuan Sun
Recent intense X-ray and UV monitoring campaigns with Swift have detected clear UV lags behind X-ray in several local active galactic nuclei (AGNs). The UV to X-ray lags are often…
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…
