Further evidence for a variable fine-structure constant from Keck/HIRES QSO absorption spectra.
MURPHY M.T., WEBB J.K. and FLAMBAUM V.V.
Abstract (from CDS):
We extend our previous searches for possible systematic errors, giving detailed analyses of potential kinematic effects, line blending, wavelength miscalibration, spectrograph temperature variations, atmospheric dispersion and isotopic/hyperfine structure effects. The latter two are potentially the most significant. However, overall, known systematic errors do not explain the results. Future many-multiplet analyses of independent QSO spectra from different telescopes and spectrographs will provide a now crucial check on our Keck/HIRES results.
