Velocity shift of Mg II and Al III broad absorption lines in quasar SDSS J134444.33+315007.6
Wei-Jian Lu, Ying-Ru Lin
We report, for the first time, a synchronized velocity shift of Mg II and Al III broad absorption lines (BALs) in quasar SDSS J134444.33+315007.6 (hereafter J1344+3150). We found t…
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…
A catalog of quasar properties from the Baryon Oscillation Spectroscopic Survey
Chen Zhi-Fu, Pan Da-Sheng, Pang Ting-Ting +1
Using the quasars with z_em < 0.9 from the Baryon Oscillation Spectroscopic Survey, we measure the spectral characteristics, including continuum and emission lines, around the Hbet…
Collective properties of quasar narrow associated absorption lines
Chen Zhi-Fu, Pan Da-Sheng
This paper statistically investigates the properties of C IV and Mg II narrow absorption lines (NALs) to look for velocity cuts that can well constrain quasar-associated NALs. The…
Narrow absorption lines complex I: one form of broad absorption line
Wei-Jian Lu, Ying-Ru Lin
We discover that some of the broad absorption lines (BALs) are actually a complex of narrow absorption lines (NALs). As a pilot study of this type of BAL, we show this discovery th…
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…
