    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...

    What is the role of the environment in shaping early-type galaxy sizes? Did it changed in the last 10 Gyr?
    Understanding galaxy evolution requires understanding the impact of cosmic time, environment, mass, and halo growth at least, because likely a combination of...

    Young and very young stars in NGC 3372, the Carina Nebula
    The advantages of using a telescope of large aperture, like the GTC, for mid-infrared imaging are demonstrated. Examples are given to compare the...
