    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...

    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...

    Counting stars from the integrated spectra of galaxies
    Over the last few decades, evolutionary population synthesis models have powered an unmatched leap forward in our understanding of galaxies. From dating the age...

    Coupling of fast and Alfvén waves in a straight bounded magnetic field with density stratification
    The theoretical understanding of the linear standing or propagating magnetohydrodynamic waves in a variety of solar coronal structures is far from complete...
