    Robust Limit on a Varying Proton-to-Electron Mass Ratio from a Single H2 System

    The variation of the dimensionless fundamental physical constant \(\mu = {m}_{p}/{m}_{e}\) can be checked through observation...

    Searching for Chameleon-Like Scalar Fields

    Using the 32-m Medicina, 45-m Nobeyama, and 100-m Effelsberg telescopes we found a statistically significant velocity offset ΔV ≈ 27 ± 3 m s − 1 (1σ) between the inversion transition in NH3(1,1) and low-J rotatio...

    Abundances in Damped Lyα Galaxies

    Damped Lyα galaxies provide a sample of young galaxies where chemical abundances can be derived throughout the whole universe with an accuracy comparable to that for the local universe. Despite a large spread ...

    Evidence of Mixing in Extremely Metal-Poor Giants

    Thirty five extremely metal-poor (EMP) giants (22 of them with a metallicity [Fe/H] ≤ -3.0) have been observed with UVES at the VLT. In these stars the abundance of lithium carbon and nitrogen and also the 12C/13

    Abundance of Heavy Elements in Extremely Metal-Poor Stars

    In the framework of the VLT Large program “First Stars” (165.N-0276(A)), we have measured the abundance of 13 heavy elements using high quality UVES spectra. In this paper, we report on the abundance of Sr and...

    Abundances in Sagittarius Stars

    The Sagittarius dwarf spheroidal is a very complex galaxy, which has undergone prolonged star formation. From the very first high resolution chemical analysis of Sgr stars, conducted using spectra obtained dur...
