PublicationThe radial abundance gradient of chlorine in the Milky Way
We determine the radial abundance gradient of Cl in the Milky Way from H II regions spectra. For the first time, the Cl/H ratios are computed by simply adding...

PublicationThe radial abundance gradient of oxygen towards the Galactic anti-centre
We present deep optical spectroscopy of eight H II regions located in the anti-centre of the Milky Way. The spectra were obtained at the 10.4 m GTC and 8.2 m...

PublicationThe Recent Star Formation History of NGC 5102
We present Hubble Space Telescope photometry of young stars in NGC 5102, a nearby gas-rich post-starburst S0 galaxy with a bright young stellar nucleus. We use...

PublicationThe recurrent impact of the Sagittarius dwarf on the star formation history of the Milky Way
Satellites orbiting disk galaxies can induce phase space features such as spirality, vertical heating and phase-mixing in their disks. Such features have also...

PublicationThe Resolved Stellar Populations in the LEGUS Galaxies1
The Legacy ExtraGalactic UV Survey (LEGUS) is a multiwavelength Cycle 21 Treasury program on the Hubble Space Telescope. It studied 50 nearby star-forming...

PublicationThe role of massive AGB stars in the early solar system composition
We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system...

NewsThe 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...

PublicationThe rotation rates of massive stars. How slow are the slow ones?
Context. Rotation plays a key role in the life cycles of stars with masses above ~8 M⊙. Hence, accurate knowledge of the rotation rates of such massive stars is...
