Varying alpha, blinding, and bias in existing measurements
Chung-Chi Lee, John K. Webb, Robert F. Carswell +3
The high resolution spectrograph ESPRESSO on the VLT allows measurements of fundamental constants at unprecedented precision and hence enables tests for spacetime variations predic…
Measuring the fine structure constant on white dwarf surfaces; uncertainties from continuum placement variations
Chung-Chi Lee, John K. Webb, Darren Dougan +2
Searches for variations of fundamental constants require accurate measurement errors. There are several potential sources of errors and quantifying each one accurately is essential…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Avoiding bias in measurements of fundamental constants from high resolution quasar spectra
John K. Webb, Chung-Chi Lee, Dinko Milaković
Recent advances in spectroscopic instrumentation and calibration methods dramatically improve the quality of quasar spectra. Supercomputer calculations show that, at high spectral…
