Fundamental physics with Espresso: Towards an accurate wavelength calibration for a precision test of the fine-structure constant
Tobias M. Schmidt, Paolo Molaro, Michael T. Murphy +56
Observations of metal absorption systems in the spectra of distant quasars allow to constrain a possible variation of the fine-structure constant throughout the history of the Univ…

Four direct measurements of the fine-structure constant 13 billion years ago
Michael R. Wilczynska, John K. Webb, Matthew Bainbridge +14
Observations of the redshift z=7.085 quasar J1120+0641 have been used to search for variations of the fine structure constant, alpha, over the redshift range 5.5 to 7.1. Observatio…
