    Stellar Kinematics and Structural Properties of Virgo Cluster Dwarf Early-type Galaxies from the SMAKCED Project. I. Kinematically Decoupled Cores and Implications for Infallen Groups in Clusters
    We present evidence for kinematically decoupled cores (KDCs) in two dwarf early-type (dE) galaxies in the Virgo cluster, VCC 1183 and VCC 1453, studied as part...

    Stellar Kinematics and Structural Properties of Virgo Cluster Dwarf Early-type Galaxies from the SMAKCED Project. II. The Survey and a Systematic Analysis of Kinematic Anomalies and Asymmetries
    We present spatially resolved kinematics and global stellar populations and mass-to-light ratios for a sample of 39 dwarf early-type (dE) galaxies in the Virgo...

    Stellar Kinematics and Structural Properties of Virgo Cluster Dwarf Early-type Galaxies from the SMAKCED Project. III. Angular Momentum and Constraints on Formation Scenarios
    We analyze the stellar kinematics of 39 dwarf early-type galaxies (dEs) in the Virgo Cluster. Based on the specific stellar angular momentum λRe and the...

    Stellar Kinematics in Double-Barred Galaxies: The σ-Hollows
    We present SAURON integral-field stellar velocity and velocity dispersion maps for four double-barred early-type galaxies: NGC 2859, NGC 3941, NGC 4725, and NGC...

    Stellar mass fraction and quasar accretion disk size in SDSS J1004+4112 from photometric follow-up
    The gravitational lens SDSS J1004+4112 was the first discovered system where a background quasar is lensed by a galaxy cluster instead of a single galaxy. We...

    Stellar mass is not the best predictor of galaxy metallicity. The gravitational potential-metallicity relation ΦZR
    Context. Interpreting the scaling relations followed by galaxies is a fundamental tool for assessing how well we understand galaxy formation and evolution...

    Stellar mass-metallicity relation throughout the large-scale structure of the Universe: CAVITY mother sample
    Context. Void galaxies are essential for understanding the physical processes that drive galaxy evolution because they are less affected by external factors...

    Stellar masses of giant clumps in CANDELS and simulated galaxies using machine learning
    A significant fraction of high redshift star-forming disc galaxies are known to host giant clumps, whose nature and role in galaxy evolution are yet to be...

    Stellar masses of star-forming galaxies at 0.3 < z < 1.2 in the GOYA survey
    Starforming galaxies with compact morphology and high optical luminosity (LBCGs) are very common at redshitfs z = 0.4 - 1.2. Those galaxies are believed to have...
