    Gaia FGK benchmark stars: Metallicity
    Context. To calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars, or "benchmark stars", with well-defined...

    Gaia FGK benchmark stars: Spectral library and abundances of α and Fe-peak elements of the third version
    Context. Accurate determination of the chemical abundances in stars plays a pivotal role in understanding stellar structure and evolution, nucleosynthesis, and...

    Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
    Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of 0.18″...

    Gaia Focused Product Release: Radial velocity time series of long-period variables
    Context. The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the...

    Gaia Focused Product Release: Sources from Service Interface Function image analysis. Half a million new sources in omega Centauri
    Context. Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM...

    Gaia Focused Product Release: Spatial distribution of two diffuse interstellar bands
    Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars and extragalactic objects that are probably caused by...

    Gaia-assisted discovery of a detached low-ionisation BAL quasar with very large ejection velocities
    We report on the discovery of a peculiar broad absorption line (BAL) quasar identified in our Gaia-assisted survey of red quasars. The systemic redshift of this...

    Gaia-assisted selection of a quasar reddened by dust in an extremely strong damped Lyman-α absorber at z = 2.226
    Damped Lyman-α absorbers (DLAs) as a class of quasi-stellar object (QSO) absorption-line systems are currently our most important source of detailed information...
