    The CoRoT-7 planetary system: two orbiting super-Earths
    We report on an intensive observational campaign carried out with HARPS at the 3.6 m telescope at La Silla on the star CoRoT-7. Additional simultaneous...

    The correlation between photometric variability and radial velocity jitter. Based on TESS and HARPS observations
    Context. Characterizing the relation between stellar photometric variability and radial velocity (RV) jitter can help us to better understand the physics behind...

    The cosmic evolution of oxygen and nitrogen abundances in star-forming galaxies over the past 10 Gyr
    Aims: The chemical evolution of galaxies on a cosmological timescale is still a matter of debate despite the increasing number of available data provided by...
  • Publication
    The cosmic waltz of Coma Berenices and Latyshev 2 (Group X). Membership, phase-space structure, mass, and energy distributions
    Context. Open clusters (OCs) are fundamental benchmarks where theories of star formation and stellar evolution can be tested and validated. Coma Berenices (Coma...

    The cosmic web from perturbation theory
    Context. Analysing the large-scale structure (LSS) in the Universe with galaxy surveys demands accurate structure formation models. Such models should ideally...

    The COSMOS-Web ring: In-depth characterization of an Einstein ring lensing system at z ∼ 2
    Aims: We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z ≈ 2 that we serendipitously discovered during the data reduction of the...

    The dark nature of GRB 051022 and its host galaxy
    Aims:We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 h and 1.15 yr after the event. It is the most...
