Testing gravity with wide binaries -- 3D velocities and distances of wide binaries from Gaia and HARPS
R. Saglia, L. Pasquini, F. Patat +5
Wide Binaries (WBs) are interesting systems to test Newton-Einstein gravity in low potentials. The basic concept is to verify whether the difference in velocity between the WB comp…

The ESPRESSO Redshift Drift Experiment I -- High-resolution spectra of the Lyman- forest of QSO J052915.80-435152.0
Andrea Trost, Catarina M. J. Marques, Stefano Cristiani +25
The measurement of the temporal evolution in the redshift of distant objects, the redshift drift, is a probe of universal expansion and cosmology. We perform the first steps toward…

Isotopic abundance of carbon in the DLA towards QSO B1331+170
Dinko Milaković, John K. Webb, Paolo Molaro +19
Chemical evolution models predict a gradual build-up of C in the universe, based on empirical nuclear reaction rates and assumptions on the properties of stellar populations…
