    Gaia Early Data Release 3. Updated radial velocities from Gaia DR2
    Context. Gaia's Early Third Data Release (EDR3) does not contain new radial velocities because these will be published in Gaia's full third data release (DR3)...

    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 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...

    Galactic bulges: the importance of early formation scenarios vs. secular evolution
    We study the stellar content of three galactic bulges with the high resolution gratings (R=7000) of the WiFeS integral field unit in order to better understand...

    Galactic cirri in deep optical imaging
    The ubiquitous presence of Galactic cirri in deep optical images represents a major obstacle to study the low surface brightness features of extragalactic...

    Galactic extinction laws - II. Hidden in plain sight, a new interstellar absorption band at 7700 Å broader than any known DIB
    We have detected a broad interstellar absorption band centred close to 7700 Å and with a full width at half-maximum (FWHM) of 176.6 ± 3.9 Å. This is the first...
