Constraint on a variation of the proton-to-electron mass ratio from H2 absorption towards quasar Q2348-011

Julija Bagdonaite, Michael T. Murphy, Lex Kaper +1

Molecular hydrogen (H2) absorption features observed in the line-of-sight to Q2348-011 at redshift zabs = 2.426 are analysed for the purpose of detecting a possible variation of th…
