Journal Article
by Lu, WJ and Lin, YR
ASTROPHYSICAL JOURNAL, ISSN 0004-637X, 09/2019, Volume 883, Issue 1, p. 30
We discover the significant (significance level of >99%) correlations between the fractional variation of the ionizing continuum and that of the C IV and/or Si...

Journal Article
Astrophysical Journal, ISSN 0004-637X, 04/2017, Volume 838, Issue 2, p. 88
In this paper we present an analysis of absorption-line variability in mini-BAL quasar LBQS 1206+ 1052. The Sloan Digital Sky Survey spectrum demonstrates that...
