    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...

    The surface of asteroid Bennu: dark, rough and dense with boulders
    Between August and December 2018, during the Approach and Preliminary Survey phases of the NASA OSIRIS-REx mission, a series of images and spectra of the...

    The synchronized dance of the Magellanic Clouds star formation history
    According to the current theories of galaxy formation, these generally form as small entities that grow through fusion, collision and accretion, eventually...

    The universal variability of the stellar initial mass function probed by the TIMER survey
    The universality of the stellar initial mass function (IMF) is one of the most widespread assumptions in modern Astronomy and yet, it might be flawed. While...
