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…

Search for cosmological mu variation from high redshift H2 absorption; a status report
Wim Ubachs, Julija Bagdonaite, Michael T. Murphy +2
Observations of H2 spectra in the line-of-sight of distant quasars may reveal a variation of the proton-electron mass ratio mu=m_p/m_e at high redshift, typically for z>2. Currentl…
