cds-question@unistra.fratomic-physicsspectroscopyMolecular transitions recently discovered at redshift z_abs_=2.059 towards the bright background quasar J2123-0050 are analysed to limit cosmological variation in the proton-to-electron mass ratio, {mu}=mp/me. Observed with the Keck telescope, the optical echelle spectrum has the highest resolving power and largest number (86) of H_2_ transitions in such analyses so far. Also, (seven) HD transitions are used for the first time to constrain {mu}-variation.2010MNRAS.403.1541Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/403/1541CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/403/1541https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/403/1541http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/403/1541https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/403/1541https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/403/1541http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/403/1541GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/403/1541/table1*Data for Lyman and Werner molecular hydrogen (H_2_) transitionsrecnoRecord number assigned by the VizieR team.
