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…

Cosmological concordance or chemical coincidence? Deuterated molecular hydrogen abundances at high redshift
J. Tumlinson, A. L. Malec, R. F. Carswell +8
We report two detections of deuterated molecular hydrogen (HD) in QSO absorption-line systems at . Toward J2123-0500, we find (HD) for a sub-DLA with me…
