    The SEGUE K Giant Survey. II. A Catalog of Distance Determinations for the SEGUE K Giants in the Galactic Halo
    We present an online catalog of distance determinations for 6036 K giants, most of which are members of the Milky Way's stellar halo. Their medium-resolution...

    The sensitivity of harassment to orbit: mass loss from early-type dwarfs in galaxy clusters
    We conduct a comprehensive numerical study of the orbital dependence of harassment on early-type dwarfs consisting of 168 different orbits within a realistic...

    The shape of oxygen abundance profiles explored with MUSE: evidence for widespread deviations from single gradients
    We characterised the oxygen abundance radial distribution of a sample of 102 spiral galaxies observed with VLT/MUSE using the O3N2 calibrator. The high spatial...

    The shapes of BCGs and normal ellipticals in nearby clusters
    We compare the apparent axial ratio distributions of the brightest cluster galaxies (BCGs) and normal ellipticals (Es) in our sample of 75 galaxy clusters from...

    The shapes of spiral arms in the S<SUP>4</SUP>G survey and their connection with stellar bars
    Context. Spiral galaxies are very common in the local Universe, but their formation, evolution, and interplay with bars remain poorly understood after more than...

    The shell elliptical galaxy NGC 2865: evolutionary population synthesis of a kinematically distinct core
    We report on the discovery of a rapidly corotating stellar and gas component in the nucleus of the shell elliptical NGC 2865. The stellar component extends ~ 0...

    The signature of high-velocity gas in the spectra of NGC 4151
    The multiwavelength emission spectrum and associated velocity field of the Seyfert prototype NGC 4151 is modeled. Since the thirties NGC 4151 has been the...

    The simultaneous low state spectral energy distribution of 1ES 2344+514 from radio to very high energies
    Context. BL Lacertae objects are variable at all energy bands on time scales down to minutes. To construct and interpret their spectral energy distribution (SED...

    The size and mass evolution of the massive galaxies over cosmic time
    Once understood as the paradigm of passively evolving objects, the discovery that massive galaxies experienced an enormous structural evolution in the last ten...
