Constraint on a varying proton-to-electron mass ratio from H2 and HD absorption at z = 2.34
M. Daprà, M. van der Laan, M. T. Murphy +1
Molecular hydrogen absorption in the damped Lyman-alpha system at z = 2.34 towards quasar Q1232+082 is analyzed in order to derive a constraint on a possible temporal variation of…

Constraint on a cosmological variation in the proton-to-electron mass ratio from electronic CO absorption
M. Daprà, M. L. Niu, E. J. Salumbides +2
Carbon monoxide (CO) absorption in the sub-damped Lyman- absorber at redshift , toward the background quasar SDSS J123714.60+064759.5 (J1237+0647), was inve…
