    The mean star formation rate of X-ray selected active galaxies and its evolution from z ~ 2.5: results from PEP-Herschel
    We study relationships between star-formation rate (SFR) and the accretion luminosity and nuclear obscuration of X-ray selected active galactic nuclei (AGNs)...

    The merger history of massive spheroids since z ˜ 1 is size-independent
    Using a compilation of 379 massive (stellar mass M ≳ 1011 M⊙) spheroid-like galaxies from the near-infrared Palomar/DEEP-2 survey, we investigated, up to z ˜ 1...

    The merger rate of extremely low mass white dwarf binaries: links to the formation of AM CVn stars and underluminous supernovae
    We study a complete, colour-selected sample of double-degenerate binary systems containing extremely low mass (ELM) ≤0.25 M&sun; white dwarfs (WDs). We show...

    The merging/AGN connection. II. Ionization of the circumnuclear regions
    We report the first results of a study of a sample of 20 galaxy mergers/interacting systems, using the VIMOS and PMAS integral field spectrographs. For each...

    The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
    Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than...

    The metal content of GR 8 and Sextans B
    Ionic abundances for two irregular dwarf galaxies belonging to the Local Group, GR 8 and Sextans B, are presented. The oxygen abundances have been found to be 0...

    The metal-poor edge of the Milky Way's "thin disc"
    Context. The emergence of the disc in our Galaxy and the relation between thick and thin disc formation and evolution is still a matter of debate. The chemo...

    The metal-poor end of the Spite plateau. I. Stellar parameters, metallicities, and lithium abundances
    Context. The primordial nature of the Spite plateau is at odds with the WMAP satellite measurements, implying a primordial Li production at least three times...
