A sub-ppm upper limit on the cosmological variations of the fine structure constant alpha
S. Muller, A. Beelen, M. Guelin +9
Absorption spectroscopy toward high-redshift quasars provides strong constraints on the putative variation of fundamental constants of physics on cosmological time scales. The subm…

New constraints on the values of the fundamental constants at a look-back time of 7.3 Gyr
Renzhi Su, Stephen J. Curran, Francoise Combes +4
The study of redshifted spectral lines can provide a measure of the fundamental constants over large look-back times. Current grand unified theories predict an evolution in these c…
