Gaia Data Release 3: The extragalactic content
(EDP Sciences, 2023-06)
[Abstract]: The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epoch survey, Gaia also observes ...
Gaia Data Release 3: Astrophysical parameters inference system (Apsis). I. Methods and content overview
(EDP Sciences, 2023-06)
[Abstract]: Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release, and were produced by the Astrophysical parameters inference system ...
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
(EDP Sciences, 2024)
[Abstract] Context. Gravitational waves from black-hole (BH) merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected based on most stellar ...
Gaia Focused Product Release: Radial velocity time series of long-period variables
(EDP Sciences, 2023)
[Abstract] Context. The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocity data planned with ...
Gaia Focused Product Release: Spatial distribution of two diffuse interstellar bands
(EDP Sciences, 2023)
[Abstract] Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars and extragalactic objects that are probably caused by large and complex molecules in the galactic interstellar ...
Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment
(EDP Sciences, 2023)
[Abstract] 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 asteroids. It extends the epoch astrometric solution over ...
Gaia Data Release 3: Summary of the content and survey properties
(EDP Sciences, 2023)
[Abstract] Context. We present the third data release of the European Space Agency’s Gaia mission, Gaia DR3. This release includes a large variety of new data products, notably a much expanded radial velocity survey and a ...
Gaia Focused Product Release: Sources from Service Interface Function image analysis: Half a million new sources in omega Centauri
(EDP Sciences, 2023)
[Abstract] 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) images were recorded for nine selected regions ...
Gaia Data Release 3: Chemical cartography of the Milky Way
(EDP Sciences, 2023-06)
[Abstract]: Context. The motion of stars has been used to reveal details of the complex history of the Milky Way, in constant interaction with its environment. Nevertheless, to reconstruct the Galactic history puzzle in ...
Gaia Data Release 3: Analysis of RVS spectra using the General Stellar Parametriser from spectroscopy
(EDP Sciences, 2023-06)
[Abstract]: Context. The chemo-physical parametrisation of stellar spectra is essential for understanding the nature and evolution of stars and of Galactic stellar populations. A worldwide observational effort from the ...
