    Stellar Disk Truncations at High z: Probing Inside-Out Galaxy Formation
    We have conducted a systematic search for stellar disk truncations in disklike galaxies at intermediate redshift (z

    Stellar dynamics of blue compact galaxies. II. Further indications of a merger in ESO 338-IG04
    Context: Luminous blue compact galaxies, common at z ~ 1 but now relatively rare, show disturbed kinematics in emission lines. Aims: As part of a programme to...

    Stellar evolution models for Z = 0.0001 to 0.03
    We have calculated a grid of empirically well tested evolutionary tracks with masses M between 0.5 and 50Msolar, spaced by approximately 0.1 in log M, and with...

    Stellar feedback and the energy budget of late-type Galaxies: missing baryons and core creation
    In a ΛCDM cosmology, galaxy formation is a globally inefficient process: it is often the case that far fewer baryons are observed in galaxy discs than expected...

    Stellar haloes of disc galaxies at z ˜ 1
    Taking advantage of the ultradeep near-infrared imaging obtained with the Hubble Space Telescope on the Hubble Ultra Deep Field, we detect and explore for the...

    Stellar haloes outshine disc truncations in low-inclined spirals
    The absence of stellar disc truncations in low-inclined spiral galaxies has been a matter of debate in the last decade. Disc truncations are often observed in...

    Stellar kinematics across the Hubble sequence in the CALIFA survey: general properties and aperture corrections
    We present the stellar kinematic maps of a large sample of galaxies from the integral-field spectroscopic survey CALIFA. The sample comprises 300 galaxies...

    Stellar kinematics and dark matter in dwarf galaxies
    In this review I will discuss the current status on determinations of the dark matter content and distribution in Milky Way dwarf spheroidals, for which the...

    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...
