Do the constants of nature couple to strong gravitational fields?
S. P. Preval, M. A. Barstow, J. B. Holberg +5
Recently, white dwarf stars have found a new use in the fundamental physics community. Many prospective theories of the fundamental interactions of Nature allow traditional constan…
Spatial variation in the fine-structure constant -- new results from VLT/UVES
Julian A. King, John K. Webb, Michael T. Murphy +5
(abridged) We present a new analysis of a large sample of quasar absorption-line spectra obtained using UVES (the Ultraviolet and Visual Echelle Spectrograph) on the VLT (Very Larg…
Localised HI 21-cm absorption towards a double-lobed z=0.24 radio galaxy
S. J. Curran, M. T. Whiting, J. K. Webb +1
We present the results of a mini-survey for associated HI 21-cm absorption at z < 0.42 with the Giant Metrewave Radio Telescope. Our targets are radio galaxies, selected on the bas…
A third HI 21-cm absorption system in the sight-line of MG J0414+0534: A redshift for Object X?
S. J. Curran, M. T. Whiting, A. Tanna +2
We report the detection of a third HI 21-cm absorber in the sight-line towards the z=2.64 quasar MG J0414+0534 (4C +05.19). In addition to the absorption at the host redshift and i…
Redshifted HI and OH absorption in radio galaxies and quasars
S. J. Curran, M. T. Whiting, M. T. Murphy +6
From a survey for redshifted HI 21-cm and OH 18-cm absorption in the hosts of a sample of radio galaxies and quasars, we detect HI in three of the ten and OH in none of the fourtee…
Atomic transition frequencies, isotope shifts, and sensitivity to variation of the fine structure constant for studies of quasar absorption spectra
J. C. Berengut, V. A. Dzuba, V. V. Flambaum +4
Theories unifying gravity with other interactions suggest spatial and temporal variation of fundamental "constants" in the Universe. A change in the fine structure constant, alpha,…
