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…
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…
Fluctuations of the intergalactic ionization field at redshift z ~ 2
I. I. Agafonova, S. A. Levshakov, D. Reimers +2
(Abridged) Aims. To probe the spectral energy distribution (SED) of the ionizing background radiation at z ~ 2 and to specify the sources contributing to the intergalactic radiatio…
