    Gaia Data Release 3. The extragalactic content
    The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as...

    Gaia DR 2 and VLT/FLAMES search for new satellites of the LMC
    A wealth of tiny galactic systems populates the surroundings of the Milky Way. However, some of these objects might have originated as former satellites of the...

    Gaia DR2 proper motions of dwarf galaxies within 420 kpc. Orbits, Milky Way mass, tidal influences, planar alignments, and group infall
    A proper understanding of the Milky Way (MW) dwarf galaxies in a cosmological context requires knowledge of their 3D velocities and orbits. However, proper...

    Gaia early DR3 systemic motions of Local Group dwarf galaxies and orbital properties with a massive Large Magellanic Cloud
    Aims: We perform a comprehensive determination of the systemic proper motions of 74 dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia...

    Galactic angular momentum in the IllustrisTNG simulation - I. Connection to morphology, halo spin, and black hole mass
    We use the TNG100 simulation of the IllustrisTNG project to investigate the stellar specific angular momenta (j *) of ~12 000 central galaxies at z = 0 in a...

    Galactic Astronomy with OTELO
    OTELO (OSIRIS Tunable Emission Line Object survey) is a project aimed at studying the low end luminosity function of emission line galaxies. A broad band survey...

    Galactic Bulges from Hubble Space Telescope Near-Infrared Camera Multi-Object Spectrometer Observations: The Lack of r1/4 Bulges
    We use Hubble Space Telescope (HST) near-infrared imaging to explore the shapes of the surface brightness profiles of bulges of S0-Sbc galaxies at high...

    Galactic bulges from Hubble Space Telescope NICMOS observations: ages and dust
    We present optical and near-infrared colour maps of the central regions of bulges of S0 and spiral galaxies obtained with WFPC2 and NICMOS on the Hubble Space...

    Galactic Bulges from Hubble Space Telescope NICMOS Observations: Central Galaxian Objects, and Nuclear Profile Slopes
    We have measured the central structural properties for a sample of S0-Sbc galaxies down to scales of ~10 pc using Hubble Space Telescope NICMOS images. Central...
