Acceleration of C iv and Si iv Broad Absorption Lines in Quasar SDSS J140058.79+260619.4
We report the discovery of a velocity shift signature in the C iv and Si iv broad absorption lines (BALs) of the quasar SDSS J140058.79+260619.4 ( z _em = 2.351). From its two-epoch spectra, we find two BAL systems (systems A and B) in C iv and/or Si iv ions. Firstly, we find obvious variations of...
