The correlations between optical/UV broad lines and X-ray emission for a large sample of quasars
J. D. Timlin, W. N. Brandt, Q. Ni +5
We present Chandra observations of 2106 radio-quiet quasars in the redshift range 1.7<z<2.7 from the Sloan Digital Sky Survey (SDSS), through data release fourteen (DR14), that do…
SDSS J094635.06+101706.1: a redshift one, very radio-loud, γ-ray emitting narrow-line Seyfert 1 galaxy
Su Yao, S. Komossa, Wen-Juan Liu +4
As hybrids of narrow-line Seyfert 1 (NLS1) galaxies and blazars, γ-ray emitting NLS1s are important probes of jet physics in the high Eddington-ratio regime. Only very few of them…
Lijiang 2.4-meter Telescope and its Instruments
Chuan-Jun Wang, Jin-Ming Bai, Yu-Feng Fan +32
Lijiang 2.4-meter Telescope(LJT), the largest common-purpose optical telescope in China, has been applied to the world-wide astronomers since 2008. It is located at Gaomeigu site,…
Spectroscopy of broad absorption line quasars at -- I: evidence for quasar winds shaping broad/narrow emission line regions
Weimin Yi, Wenwen Zuo, Jinyi Yang +6
We present an observational study of 22 broad absorption line quasars (BAL QSOs) at based on optical/near-IR spectroscopy, aiming to investigate quasar wind…
