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: 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: Asteroid orbital solution. Properties and assessment
Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000...
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 white dwarfs within 40 pc - I. Spectroscopic observations of new candidates
We present a spectroscopic survey of 230 white dwarf candidates within 40 pc of the Sun from the William Herschel Telescope and Gran Telescopio Canarias. All...
Gaia white dwarfs within 40 pc II: the volume-limited Northern hemisphere sample
We present an overview of the sample of Northern hemisphere white dwarfs within 40 pc of the Sun detected from Gaia Data Release 2 (DR2). We find that 521...
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...
