Gaia Early Data Release 3: Summary of the Contents and Survey Properties
(EDP Sciences, 2021)
[Abstract] Context. We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented with the list of ...
Gaia Early Data Release 3: The Galactic Anticentre
(EDP Sciences, 2021)
[Abstract] Aims. We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of different aspects of the Milky Way structure and evolution and we provide, at the same time, a ...
Distributed Fast Self-Organized Maps for Massive Spectrophotometric Data Analysis
(MDPI AG, 2018-05-03)
[Abstract] Analyzing huge amounts of data becomes essential in the era of Big Data, where databases are populated with hundreds of Gigabytes that must be processed to extract knowledge. Hence, classical algorithms must be ...
Gaia Early Data Release 3: Acceleration of the Solar System from Gaia Astrometry
(EDP Sciences, 2021)
[Abstract] Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter astrometric ...
Gaia Early Data Release 3: Structure and Properties of the Magellanic Clouds
(EDP Sciences, 2021)
[Abstract] Context. This work is part of the Gaia Data Processing and Analysis Consortium papers published with the Gaia Early Data Release 3 (EDR3). It is one of the demonstration papers aiming to highlight the improvements ...
Gaia Data Release 3: Apsis. II. Stellar parameters
(EDP Sciences, 2023-06)
[Abstract]: Context. The third Gaia data release (Gaia DR3) contains, beyond the astrometry and photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra (BP and RP) and the spectrograph ...
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
(EDP Sciences, 2021)
[Abstract] Aims. We produce a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3. We characterise the catalogue through comparisons to the full data release, ...
Stellar ages, masses, extinctions, and orbital parameters based on spectroscopic parameters of Gaia DR3
(EDP Sciences, 2023)
[Abstract]: Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these ...
Solid confirmation of the broad DIB around 864.8nm using stacked Gaia–RVS spectra
(EDP Sciences, 2022)
[Abstract]: Context. Studies of the correlation between different diffuse interstellar bands (DIBs) are important for exploring their origins. However, the Gaia–RVS spectral window between 846 and 870 nm contains few DIBs, ...
GUASOM: An Adaptive Visualization Tool for Unsupervised Clustering in Spectrophotometric Astronomical Surveys
(Springer, 2022)
[Abstract] We present an adaptive visualization tool for unsupervised classification of astronomical objects in a Big Data context such as the one found in the increasingly popular large spectrophotometric sky surveys. ...
