Robust Constraint on a Drifting Proton-to-Electron Mass Ratio at z=0.89 from Methanol Observation at Three Radio Telescopes

Julija Bagdonaite, Mario Daprà, Paul Jansen +5

A limit on a possible cosmological variation of the proton-to-electron mass ratio is derived from methanol (CHOH) absorption lines in the benchmark PKS1830211 lensing ga…

Analysis of Molecular Hydrogen Absorption toward QSO B0642-5038 for a Varying Proton-to-Electron Mass Ratio

Julija Bagdonaite, Wim Ubachs, Michael T. Murphy +1

Rovibronic molecular hydrogen (H) transitions at redshift towards the background quasar B06425038 are examined for a possible cosmological variati…
