Identifying Radio Active Galactic Nuclei with Machine Learning and Large-Area Surveys
Xu-Liang Fan, Jie Li
Context. Active galactic nuclei (AGNs) and star forming galaxies (SFGs) are the primary sources of extragalactic radio sky. But it is difficult to distinguish the radio emission pr…
MWA and VLA Observations of Diffuse Radio Lobes in M 87
Linhui Wu, Fu-Guo Xie, Qian Zheng +12
This study investigates the projected, quasi-symmetric -scale diffuse radio lobes surrounding the giant elliptical galaxy M\,87, utilizing well-sampled wideband ($\…
Mid-Infrared Properties of Narrow-Line Seyfert 1 Galaxies Detected by LoTSS DR2
Xu-Liang Fan
Narrow-line Seyfert 1 galaxies (NLS1s), a subclass of active galactic nuclei (AGNs) at early stage of accretion process, are also found to host relativistic jets. However, currentl…
Reddening of the BLR and NLR in AGN From a Systematic Analysis of Balmer Decrement
Kai-Xing Lu, Yinghe Zhao, Jin-Ming Bai +1
We selected an active galactic nuclei (AGN) sample () from Sloan Digital Sky Survey Data Release 7, and measured the broad- () and narrow-line…
Constraints on the composition, magnetization, and radiative efficiency in jet of blazar
Xu-Liang Fan, Qingwen Wu, Neng-Hui Liao
The composition and energy dissipation in jets are two of the fundamental questions of jet physics that are not fully understood. In this paper, we attempt to constrain the composi…
-band host galaxy contamination of TeV -ray blazar Mrk 501: effects of the aperture size and seeing
Hai-Cheng Feng, Hong-Tao Liu, Ying-He Zhao +3
We simulated the -band contribution of the host galaxy of TeV -ray BL Lac object Mrk 501 in different aperture sizes and seeing conditions . The intensive observations were r…
Search for intra-day optical variability in Mrk 501
Hai-Cheng Feng, H. T. Liu, X. L. Fan +5
We present our observations of the optical intra-day variability (IDV) in -ray BL Lac object Mrk 501. The observations were run with the 1.02 m and 2.4 m optical telescopes at Y…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. V. A New Size-Luminosity Scaling Relation for the Broad-Line Region
Pu Du, Kai-Xing Lu, Zhi-Xiang Zhang +12
This paper reports results of the third-year campaign of monitoring super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs) between 2014-2015. Ten…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. IV. H Time Lags and Implications for Super-Eddington Accretion
Pu Du, Chen Hu, Kai-Xing Lu +13
We have completed two years of photometric and spectroscopic monitoring of a large number of active galactic nuclei (AGNs) with very high accretion rates. In this paper, we report…
