Chandra and MMT observations of low-mass black hole active galactic nuclei accreting at low rates in dwarf galaxies
W. Yuan, H. Zhou, L. Dou +3
We report on Chandra X-ray observations of four candidate low-mass black hole (<10^6Msun) active galactic nuclei (AGNs) that have the estimated Eddington ratios among the lowest (~…

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…

Two extreme double-peaked line emitters in the Sloan Digital Sky Survey
T. G. Wang, X. B. Dong, X. G. Zhang +3
Double-peaked Balmer lines have been observed in about 150 AGNs and were interpreted preferably as emission from relativistic accretion disks. In this paper, we report the discover…
