A possible new interpretation of the results of $\Delta \alpha /\alpha$ from QSO absorption lines

Abstract

The measurement of $\Delta \alpha /\alpha$ from the QSO absorption lines of Fe_II taken at two different redshifts (Quast et al, Levshakov et al) is compared with the result based on the 23 data points also obtained from VLT/UVES (Chand et al), to demonstrate that the apparent oscillatory time-dependence fitting the latter taken at face value is reinforced by the former claimed to be of much better accuracy.
