An extensive study of blazar broad emission line: Changing-look blazars and Baldwin effect
Hubing Xiao, Junhui Fan, Zhihao Ouyang +4
It is known that the blazar jet emissions are dominated by non-thermal radiation while the accretion disk jets are normally dominated by thermal emission. In this work, our aim is…
The 2175 Å~ Bump Features in FeLoBAL Quasars: One Indicator of MW-like Dust in the Nuclear Region of Quasar
Shaohua Zhang, Jian Ge, Tuo Ji +8
To investigate the properties of dust in the nuclear region of quasars, we explored the extinction curves of the iron low-ionization broad absorption line (FeLoBAL) quasar SDSS J16…
Quasar 2175 Å dust absorbers II: Correlation analysis and relationship with other absorption line systems
Jingzhe Ma, Jian Ge, J. Xavier Prochaska +6
We present the cold neutral content (H I and C I gas) of 13 quasar 2175 Å dust absorbers (2DAs) at = 1.6 - 2.5 to investigate the correlation between the presence of the UV…
Ultraviolet and Optical Emission-line Outflows in the Heavily Obscured Quasar SDSS J000610.67+121501.2: At the Scale of the Dusty Torus and Beyond
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +7
Broad emission-line outflows of active galactic nuclei (AGNs) have been proposed for many years but are very difficult to quantitatively study because of the coexistence of the gra…
Random number generation with cosmic photons
Cheng Wu, Bing Bai, Yang Liu +14
Random numbers are indispensable for a variety of applications ranging from testing physics foundation to information encryption. In particular, nonlocality tests provide a strong…
Evidence for Fluorescent Fe II Emission from Extended Low Ionization Outflows in Obscured Quasars
Tinggui Wang, Gary Ferland, Chenwei Yang +2
Recent studies have shown that outflows in at least some broad absorption line (BAL) quasars are extended well beyond the putative dusty torus. Such outflows should be detectable i…
