H Lyman and Werner band lines and their sensitivity for a variation of the proton-electron mass ratio in the gravitational potential of white dwarfs
E. J. Salumbides, J. Bagdonaite, H. Abgrall +2
Recently an accurate analysis of absorption spectra of molecular hydrogen, observed with the Cosmic Origins Spectrograph aboard the Hubble Space Telescope, in the photosphere of wh…
The inhomogeneous ISM toward PKS1830-211 SW - A detailed view on molecular gas at a look-back time of 7.5 Gyr
A. Schulz, C. Henkel, K. M. Menten +4
Based on measurements with the Effelsberg 100-m telescope, a multi-line study of molecular species is presented toward the south-western source of the gravitational lens system PKS…
Effect of soil temperature on one-way optical frequency transfer through dense-wavelength-division-multiplexing fibre links
T. J. Pinkert, O. Böll, G. S. M. Jansen +8
Results of optical frequency transfer over a carrier-grade dense-wavelength-division-multiplexing (DWDM) optical fibre network are presented. The relation between soil temperature…
and level energies of D
E. J. Salumbides, D. Bailly, M. Vervloet +1
Accurate absolute level energies of the , and , rovibrational quantum states of molecular deuterium are derived by combini…
Limits on a Gravitational Field Dependence of the Proton--Electron Mass Ratio from H in White Dwarf Stars
Julija Bagdonaite, Edcel J. Salumbides, Simon P. Preval +4
Spectra of molecular hydrogen (H) are employed to search for a possible proton-to-electron mass ratio () dependence on gravity. The Lyman transitions of H, observed with…
Ramsey-type microwave spectroscopy on CO ()
A. J. de Nijs, W. Ubachs, H. L. Bethlem
Using a Ramsey-type setup, the lambda-doublet transition in the level of the state of CO was measured to be 394 064 870(10) Hz. In our molecular beam apparatus,…
Rayleigh-Brillouin scattering of carbon dioxide
Ziyu Gu, Wim Ubachs, Willem van de Water
The spectral lineshape of spontaneous Rayleigh-Brillouin scattering in CO2 is studied in a range of pressures. The spectrum is influenced by the bulk viscosity, which is a relaxati…
