The correlated variations of C IV narrow absorption lines and quasar continuum
Zhi-Fu Chen, Ting-Ting Pang, Bing He +1
We assemble 207 variable quasars from the Sloan Digital Sky Survey, all with at least 3 observations, to analyze C IV narrow absorption doublets, and obtain 328 C IV narrow absorpt…

The associated absorption features in quasar spectra of the Sload Digital Sky survey .I. \MgII\ absorption doublets
Chen Zhi-Fu, Huang Wei-Rong, Pang Ting-Ting +5
Using the SDSS spectra of quasars included in the DR7Q or DR12Q catalogs, we search for Mg II narrow absorption doublets in the spectra data around Mg II emission lines. We obtain…

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…
