A precise deuterium abundance: Re-measurement of the z=3.572 absorption system towards the quasar PKS1937-101
S. Riemer-Sørensen, S. Kotuš, J. K. Webb +4
The primordial deuterium abundance probes fundamental physics during the Big Bang Nucleosynthesis and can be used to infer cosmological parameters. Observationally, the abundance c…
Probing the Gravitational Dependence of the Fine-Structure Constant from Observations of White Dwarf Stars
Matthew B. Bainbridge, Martin A. Barstow, Nicole Reindl +12
Hot white dwarf stars are the ideal probe for a relationship between the fine-structure constant and strong gravitational fields, providing us with an opportunity for a direct obse…
Network of sensitive magnetometers for urban studies
T. A. Bowen, E. Zhivun, A. Wickenbrock +6
The magnetic signature of an urban environment is investigated using a geographically distributed network of fluxgate magnetometers deployed in and around Berkeley, California. The…
Modeling long-range wavelength distortions in quasar absorption echelle spectra
Vincent Dumont, John K. Webb
Spectra observed with the Ultraviolet and Visual Echelle Spectrograph (UVES) on the European Southern Observatory's VLT exhibit long-range wavelength distortions. These distortions…
