Fundamental physics with ESPRESSO: a new determination of the D/H ratio towards PKS1937-101
Francesco Guarneri, Luca Pasquini, Valentina D'Odorico +19
Primordial abundances of light elements are sensitive to the physics of the early Universe and can directly constrain cosmological quantities, such as the baryon-to-photon ratio $η…
Fundamental physics with ESPRESSO: Constraints on Bekenstein and dark energy models from astrophysical and local probes
C. J. A. P. Martins, S. Cristiani, G. Cupani +21
Dynamical scalar fields in an effective four-dimensional field theory are naturally expected to couple to the rest of the theory's degrees of freedom, unless some new symmetry is p…
Fundamental Physics with ESPRESSO, Constraining a simple parametrisation for varying
Vitor da Fonseca, Tiago Barreiro, Nelson J. Nunes +24
The spectrograph ESPRESSO recently obtained a limit on the variation of the fine-structure constant, , through measurements along the line of sight of a bright quasar with a pre…
