Further Evidence for Cosmological Evolution of the Fine Structure Constant
J. K. Webb, M. T. Murphy, V. V. Flambaum +5
We describe the results of a search for time variability of the fine structure constant, alpha, using absorption systems in the spectra of distant quasars. Three large optical data…
The 2dF Galaxy Redshift Survey: Near Infrared Galaxy Luminosity Functions
Shaun Cole, Peder Norberg, Carlton Baugh +24
We combine the 2MASS extended source catalogue and the 2dFGRS to produce an IR selected galaxy catalogue with 17,173 measured redshifts. We use this extensive dataset to estimate t…
Further constraints on variation of the fine structure constant from alkali doublet QSO absorption lines
M. T. Murphy, J. K. Webb, V. V. Flambaum +2
Comparison of quasar absorption line spectra with laboratory spectra provides a precise probe for variability of the fine structure constant, alpha, over cosmological time-scales.…
Possible evidence for a variable fine structure constant from QSO absorption lines: systematic errors
M. T. Murphy, J. K. Webb, V. V. Flambaum +2
Comparison of quasar absorption spectra with laboratory spectra allow us to probe possible variations in the fundamental constants over cosmological time-scales. In a companion pap…
Possible evidence for a variable fine structure constant from QSO absorption lines: motivations, analysis and results
M. T. Murphy, J. K. Webb, V. V. Flambaum +5
An experimental search for variation in the fundamental coupling constants is strongly motivated by modern high-energy physics theories. Comparison of quasar absorption line spectr…
An Estimate of the Age Distribution of Terrestrial Planets in the Universe: Quantifying Metallicity as a Selection Effect
Charles H. Lineweaver
Planets like the Earth cannot form unless elements heavier than helium are available. These heavy elements, or `metals', were not produced in the big bang. They result from fusion…
