Fundamental constants and high resolution spectroscopy
P. Bonifacio, H. Rahmani, J. B. Whitmore +14
Absorption-line systems detected in high resolution quasar spectra can be used to compare the value of dimensionless fundamental constants such as the fine-structure constant, alph…
A new method for detecting velocity shifts and distortions between optical spectra
Tyler M. Evans, Michael T. Murphy
Recent quasar spectroscopy from the VLT and Keck telescopes suggests that fundamental constants may not actually be constant. To better confirm or refute this result, systematic er…
The UVES Large Program for Testing Fundamental Physics II: Constraints on a Change in μ Towards Quasar HE 0027-1836
H. Rahmani, M. Wendt, R. Srianand +14
We present an accurate analysis of the H2 absorption lines from the zabs ~ 2.4018 damped Lyα system towards HE 0027-1836 observed with the Very Large Telescope Ultraviolet and Visu…
The UVES Large Program for Testing Fundamental Physics: I Bounds on a change in alpha towards quasar HE 2217-2818
P. Molaro, M. Centurion, J. B. Whitmore +14
Absorption line systems detected in quasar spectra can be used to compare the value of the fine-structure constant, α, measured today on Earth with its value in distant galaxies. I…
