    Cosmic variance in [O/Fe] in the Galactic disk
    We examine the distribution of the [O/Fe] abundance ratio in stars across the Galactic disk using H-band spectra from the Apache Point Galactic Evolution...

    Cosmic-ray acceleration and escape from supernova remnant W44 as probed by Fermi-LAT and MAGIC
    Context. The supernova remnant (SNR) W44 and its surroundings are a prime target for studying the acceleration of cosmic rays (CRs). Several previous studies...

    COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses. IX. Time delays, lens dynamics and baryonic fraction in HE 0435-1223
    We present accurate time delays for the quadruply imaged quasar HE 0435-1223. The delays were measured from 575 independent photometric points obtained in the R...

    COSMOS-Web: A history of galaxy migrations over the stellar mass–star formation rate plane
    Context. The stellar mass-star formation rate (M ⋆ ‑ SFR) plane is an essential diagnostic to separate galaxy populations. However, we still lack a clear...

    COSMOS-Web: Stellar mass assembly in relation to dark matter halos across 0.2 < z < 12 of cosmic history
    We study the stellar mass assembly of galaxies via the stellar mass function (SMF) and the coevolution with dark matter halos via abundance matching in the...

    COSMOS-Web: The emergence of the Hubble sequence
    Context. The first JWST deep surveys have expanded our understanding of the morphological evolution of galaxies across cosmic time. The improved spatial...

    COSMOS2025: The COSMOS-Web galaxy catalog of photometry, morphology, redshifts, and physical parameters from JWST, HST, and ground-based imaging
    We present COSMOS2025, the COSMOS-Web catalog of photometry, morphology, photometric redshifts, and physical parameters for more than 700 000 galaxies in the...

    Coudé-feed stellar spectral library - atmospheric parameters
    Context. Empirical libraries of stellar spectra play an important role in different fields. For example, they are used as reference for the automatic...

    Could very low-metallicity stars with rotation-dominated orbits have been driven by the bar?
    The most metal-poor stars (e.g., [Fe/H] ≤ –2.5) are the ancient fossils from the early assembly epoch of our Galaxy. They very likely formed before the the...
