The improved Amati correlations from Gaussian copula
Yang Liu, Fuyong Chen, Nan Liang +3
In this paper, we obtain two improved Amati correlations of the Gamma-Ray burst (GRB) data via a powerful statistical tool called copula. After calibrating, with the low-redshift G…
Deep Learning for Strong Lensing Search: Tests of the Convolutional Neural Networks and New Candidates from KiDS DR3
Zizhao He, Xinzhong Er, Qian Long +6
Convolutional Neutral Networks have been successfully applied in searching for strong lensing systems, leading to discoveries of new candidates from large surveys. On the other han…
SNe Ia as a cosmological probe
Xiangcun Meng, Yan Gao, Zhanwen Han
Type Ia supernovae luminosities can be corrected to render them useful as standard candles able to probe the expansion history of the universe. This technique was successful applie…
Supermassive black holes with high accretion rates in active galactic nuclei: I. First results from a new reverberation mapping campaign
P. Du, C. Hu, K. -X. Lu +7
We report first results from a large project to measure black hole (BH) mass in high accretion rate active galactic nuclei (AGNs). Such objects may be different from other AGNs in…
A Bayesian Approach to Estimate the Size and Structure of the Broad-line Region in Active Galactic Nuclei Using Reverberation Mapping Data
Yan-Rong Li, Jian-Min Wang, Luis C. Ho +2
This is the first paper in a series devoted to systematic study of the size and structure of the broad-line region (BLR) in active galactic nuclei (AGNs) using reverberation mappin…
Anomalously Steep Reddening Law in Quasars: An Exceptional Example Observed in IRAS14026+4341
Peng Jiang, Hongyan Zhou, Tuo Ji +7
A fraction of the heavily reddened quasars require a reddening curve which is even steeper than that of the Small Magellanic Cloud. In this paper, we thoroughly characterize the an…
The radio structure of 3C 316, a galaxy with double-peaked narrow optical emission lines
T. An, Z. Paragi, S. Frey +6
The galaxy 3C\,316 is the brightest in the radio band among the optically-selected candidates exhibiting double-peaked narrow optical emission lines. Observations with the Very Lar…
A comparative study of optical/ultraviolet variability of narrow-line Seyfert 1 and broad-line Seyfert 1 active galactic nuclei
Y. L. Ai, W. Yuan, H. Zhou +4
The ensemble optical/ultraviolet variability of narrow-line Seyfert 1 (NLS1) type active galactic nuclei (AGNs) is investigated, based on a sample selected from the Sloan Digital S…
Double-peaked narrow emission-line galaxies from Sloan Digital Sky Survey. I. Sample and basic properties
Jun-Qiang Ge, Chen Hu, Jian-Min Wang +2
Recently, much attention has been given to double-peaked narrow emission-line galaxies, some of which are suggested to be related with merging galaxies. We make a systematic search…
The Evolution and Star Formation History of M33
Xiaoyu Kang, Ruixiang Chang, Jun Yin +4
We construct a parameterized model to explore the main properties of the star formation history of M33. We assume that the disk originates and grows by the primordial gas infall an…
Discovery of six high-redshift quasars with the Lijiang 2.4m telescope and the Multiple Mirror Telescope
Xue-Bing Wu, Wen-Wen Zuo, Qian Yang +6
Quasars with redshifts greater than 4 are rare, and can be used to probe the structure and evolution of the early universe. Here we report the discovery of six new quasars with …
Decoding spectral energy distributions of dust-obscured starburst-AGN
Yunkun Han, Zhanwen Han
We present BayeSED, a general purpose tool for doing Bayesian analysis of SEDs by using whatever pre-existing model SED libraries or their linear combinations. The artificial neura…
VLBI observations of 10 CSO candidates: expansion velocities of hot spots
Tao An, Fang Wu, Jun Yang +11
Observations of ten Compact Symmetric Objects ({\rm CSO}) candidates have been made with the Very Long Baseline Array at 8.4 GHz in 2005 and with a combined Chinese and European VL…
On the Evolution of the Cores of Radio Sources and Their Extended Radio Emission
Zunli Yuan, Jiancheng Wang
The work in this paper aims at determining the evolution and possible co-evolution of radio-loud active galactic nuclei (AGNs) and their cores via their radio luminosity functions…
The optical variability of steep-spectrum radio quasars in the SDSS Stripe 82 region
Minfeng Gu, Y. L. Ai
While there are a lot of investigations on the optical variability of flat-spectrum radio quasars (FSRQs), not much work has been done on the optical variability of steep-spectrum…
Constraining broad-line regions from time lags of broad emission lines relative to radio emission
H. T. Liu, J. M. Bai, J. M. Wang +1
In this paper, a new method is proposed to estimate the broad-line region sizes of UV lines . It is applied to 3C 273. First, we derive the time lags of rad…
Coexistence of Gravitationally Bound and Radiation Driven CIV Emission Line Regions in Active Galactic Nuclei
Huiyuan Wang, Tinggui Wang, Hongyan Zhou +4
There are mutually contradictory views in the literature of the kinematics and structure of high-ionization line (e.g. CIV) emitting regions in active galactic nuclei (AGNs). Two k…
