The detections of inflowing gas from narrow absorption lines at the parsec scale
Zhi-Fu Chen, Minfeng Gu, Zhicheng He +4
Inflows at the dusty torus and smaller scales is crucial to investigate the process of supermassive black hole accretion. However, only few cases of inflowing gas at small scales h…
New Constraint of the Hubble Constant by Proper Motions of Radio Components Observed in AGN Twin-jets
Wei-Jian Lu, Yi-Ping Qin
As the advent of precision cosmology, the Hubble constant () inferred from the Lambda Cold Dark Matter fit to the Cosmic Microwave Background data is increasingly in tension w…
Correlation between the ionizing continuum and variable C iv broad absorption line in multi-epoch observations of SDSS J141007.74+541203.3
Hong-Yan Huang, Cai-Juan Pan, Wei-Jian Lu +9
Correlation between the variations of quasar absorption lines and the ionizing continuum have been recently confirmed in systematic studies. However, no convincing individual case…
Correlation between the variation of the ionizing continuum and broad absorption lines
Wei-Jian Lu, Ying-Ru Lin, Yi-Ping Qin
In this Letter, we present an analysis of the relation between the variability of broad absorption lines (BALs) and that of the continuum. Our sample is multi-epoch observations of…
Evidence for photoionization-driven variability in narrow absorption lines
Wei-Jian Lu, Ying-Ru Lin, Yi-Ping Qin +10
In this Letter, we report the discovery of a strong correlation between the variability of narrow absorption lines (NALs) and the ionizing continuum from a two-epoch spectra sample…
Catalog of narrow C IV absorption lines in BOSS (II): for quasars with zem > 2.4
Zhi-Fu Chen, Yi-Ping Qin, Ming Qin +2
As the second work in a series of papers aiming to detect absorption systems in the quasar spectra of the Baryon Oscillation Spectroscopic Survey, we continue the analysis of Paper…
