    The role of active galactic nucleus feedback on the evolution of dwarf galaxies from cosmological simulations: Supermassive black holes suppress star formation in low-mass galaxies
    Recent observational studies suggest that feedback from active galactic nuclei (AGNs)—the energetic centres powered by supermassive black holes—may play an...

    The role of the Sagittarius dwarf galaxy in the evolution of our Galaxy
    The European Space Agency's Gaia mission is revolutionising our understanding on how the Milky Way, the spiral galaxy we inhabit, has formed and evolved. Gaia...

    The rotation rates of massive stars: How slow are the slow ones?
    Rotation plays a key role in the life cycles of stars with masses above 8 Msun. Hence, accurate knowledge of the rotation rates of such massive stars is...

    The spectroscopic Hertzsprung-Russell diagram of Galactic massive stars.
    The distribution of stars in the Hertzsprung-Russell diagram narrates their evolutionary history and directly assesses their properties. Placing stars in this...

    The Star Formation History of M32.
    We use deep Hubble Space Telescope Advanced Camera for Surveys/High Resolution Channel observations of a field within M32 (F1) and an M31 background field (F2)...

    The star formation rate evolution of low-mass galaxies as seen by OTELO
    We present the analysis of a sample of Halpha, Hbeta and [OII] emission line galaxies from the OTELO survey, with masses typically below log(M */Msun) = 9.4 and...

    The stellar initial mass function at 0.9 < z < 1.5.
    We explore the stellar initial mass function (IMF) of a sample of 49massive quiescent galaxies (MQGs) at 0.9

    The stellar orbit distribution in present-day galaxies inferred from the CALIFA survey
    Galaxy formation entails the hierarchical assembly of mass, along with the condensation of baryons and the ensuing, self-regulating star formation. The stars...

    The suppression of star formation by powerful active galactic nuclei.
    The old, red stars that constitute the bulges of galaxies, and the massive black holes at their centres, are the relics of a period in cosmic history when...
