The Study of Circumgalactic Medium with Quasar Pairs
Zhi-Fu Chen, Huan-Chang Qin, Jin-Ting Cai +4
We have collected 10025 foreground-background quasar pairs with projected distances kpc from the large quasar catalog of the SDSS DR16Q. We investigate the properties of…

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…
