The Population of Type~1 Active Galactic Nuclei in Dark Energy Spectroscopic Instrument. I. Profile-dependent Measurements of the Low-redshift Sample

Zhu-Heng Yao, Wei-Jian Guo, Shuo Zhai +8

We present a spectral analysis of a large sample of low-redshift type 1 active galactic nuclei (AGNs) selected from the first data release of the Dark Energy Spectroscopic Instrume…

The intra-day Optical Monitoring of BL Lacerate Object 1ES 1218+304 at Its Highest X-ray Flux Level

S. S. Sun, H. L. Li, X. Yang +3

We here report a monitor of the BL Lac object 1ES 1218+304 in both B- and R-bands by the GWAC-F60A telescope in eight nights, when it was triggerd to be at its highest X-ray flux i…

Local Active Galactic Nuclei with Large Broad-Hα Variability Reside in Red Galaxies

Wen-Juan Liu, Paulina Lira, Su Yao +4

Inspired by our serendipitous discovery of six AGNs with varying broad-Halpha fluxes over years out of our searching for intermediate-mass black holes (IMBHs), we conduct a systema…

Low-mass and High-mass Supermassive Blackholes In Radio-Loud AGNs Are Spun-up in Different Evolution Paths

J. Wang, M. Z. Kong, S. F. Liu +3

How Supermassive Blackholes (SMBHs) are spun-up is a key issue of modern astrophysics. As an extension of the study in Wang et al. (2016), we here address the issue by comparing th…

SDSS J090152.05+624342.6: A New "Overlapping-Trough" FeLoBAL Quasar At Z

J. Wang, D. W. Xu, J. Y. Wei

We here report an identification of SDSS J090152.04+624342.6 as a new "overlapping-trough" iron low-ionization broad absorption line quasar at redshift of . No strong var…

Deepest view of AGN X-ray variability with the 7 Ms Chandra Deep Field-South survey

X. C. Zheng, Y. Q. Xue, W. N. Brandt +13

We systematically analyze X-ray variability of active galactic nuclei (AGNs) in the 7~Ms \textit{Chandra} Deep Field-South survey. On the longest timescale ( years), we…
