The spin-forbidden vacuum-ultraviolet absorption spectrum of 14N15N
A. N. Heays, B. R. Lewis, N. de Oliveira +1
Photoabsorption spectra of were recorded at high resolution with a vacuum-ultraviolet Fourier-Transform spectrometer fed by synchrotron radiation in…
Precision spectroscopy and comprehensive analysis of perturbations in the ) state of CO
R. Hakalla, T. M. Trivikram, A. N. Heays +4
We have reinvestigated the A level of CO\ using new high-resolution spectra obtained via multi-photon laser excitation as well as with synchrotron-based F…
Discovery of a Perseus-like cloud in the early Universe: HI-to-H2 transition, carbon monoxide and small dust grains at zabs=2.53 towards the quasar J0000+0048
P. Noterdaeme, J. -K. Krogager, S. Balashev +10
We present the discovery of a molecular cloud at zabs=2.5255 along the line of sight to the quasar J0000+0048. We perform a detailed analysis of the absorption lines from ionic, ne…
VUV-synchrotron absorption studies of N and CO at 900 K
M. L. Niu, A. N. Heays, S. Jones +5
Photoabsorption spectra of N and CO were recorded at 900K, using the vacuum-ultraviolet Fourier-transform spectrometer at the DESIRS beamline of synchrotron SOLEIL. These high-…
Precision spectroscopy of the () rovibrational splittings in H, HD and D
Ming Li Niu, Edcel J. Salumbides, Gareth. D. Dickenson +2
Accurate experimental values for the vibrational ground tone or fundamental vibrational energy splitting of H, HD, and D are presented. Absolute accuracies of $2\times10^{-…
Robust Constraint on a Drifting Proton-to-Electron Mass Ratio at z=0.89 from Methanol Observation at Three Radio Telescopes
Julija Bagdonaite, Mario Daprà, Paul Jansen +5
A limit on a possible cosmological variation of the proton-to-electron mass ratio is derived from methanol (CHOH) absorption lines in the benchmark PKS1830211 lensing ga…
