    Tracing the Evolution of Dust Obscured Star Formation and Accretion Back to the Reionisation Epoch with SPICA
    Our current knowledge of star formation and accretion luminosity at high redshift (z > 3-4), as well as the possible connections between them, relies mostly on...

    Triggered star formation in a merging, gas-rich dwarf galaxy around NGC 7241
    Using multiwavelength kinematic and photometric data we have analysed the gaseous and stellar properties of a previously uncharacterized low-mass star-forming...

    Triggered star formation on the borders of H II regions
    The formation of massive stars is not fully understood. The high luminosity and temperature of massive protostars complicate the accretion mechanism at work in...

    Ultracool Subdwarfs: The Halo Population Down to the Substellar Limit
    Ultracool subdwarfs are low luminosity, late-type M and L dwarfs that exhibit spectroscopic indications of subsolar metallicity and halo kinematics. Their...

    Unbiased Large Spectroscopic Surveys of Galaxies Selected by SPICA Using Dust Bands
    The mid-infrared range contains many spectral features associated with large molecules and dust grains such as polycyclic aromatic hydrocarbons and silicates...

    Unbiased studies of galactic outflows
    Large-scale outflows from galaxies are a crucially important yet poorly understood aspect of galaxy evolution. They redistribute gas and metals into the IGM...

    Using color-magnitude diagrams and spectroscopy to derive star formation histories: VLT observations of Fornax
    We undertook a study of the star formation and chemical enrichment history of the Fornax dSph galaxy. We used the VLT with FORS1 to obtain photometry reaching...

    Very high redshift quasars and the rapid emergence of supermassive black holes
    The observation of quasars at very high redshift such as Pōniuā'ena is a challenge for models of supermassive black hole (SMBH) formation. This work presents a...

    Violent star formation in NGC 2363
    We present narrowband H-alpha imaging and long-slit optical and near-infrared spectroscopy of the giant H II region NGC 2363. The spectroscopic data are taken...
