A new constraint on the time dependence of the proton-to-electron mass ratio. Analysis of the Q 0347-383 and Q 0405-443 spectra
A. Ivanchik, P. Petitjean, D. Varshalovich +5
A new limit on the possible cosmological variation of the proton-to-electron mass ratio μ=m_p/m_e is estimated by measuring wavelengths of H_2 lines of Lyman and Werner bands from…

Does the proton-to-electron mass ratio vary in the course of cosmological evolution?
A. Ivanchik, P. Petitjean, E. Rodriguez +1
The possible cosmological variation of the proton-to-electron mass ratio was estimated by measuring the H_2 wavelengths in the high-resolution spectrum of the quasar Q~0347-382. Ou…
