Searching for new physics using high precision absorption spectroscopy; continuum placement uncertainties and the fine structure constant in strong gravity
Chung-Chi Lee, John K. Webb, Darren Dougan +3
Searches for variations of fundamental constants require a comprehensive understanding of measurement errors. This paper examines a source of error that is usually overlooked: the…
Searching for new physics using high precision absorption spectroscopy; continuum placement uncertainties and towards the quasar PHL957
John K. Webb, Chung-Chi Lee, Dinko Milaković +3
Detecting or placing upper limits on spacetime variations of fundamental constants requires quantifying every potential source of uncertainty. We continue our previous study into t…
Isotopic abundance of carbon in the DLA towards QSO B1331+170
Dinko Milaković, John K. Webb, Paolo Molaro +19
Chemical evolution models predict a gradual build-up of C in the universe, based on empirical nuclear reaction rates and assumptions on the properties of stellar populations…
