Gaia Early Data Release 3. Building the Gaia DR3 source list -- Cross-match of Gaia observations
F. Torra, J. Castañeda, C. Fabricius +12
The Gaia Early Data Release 3 (Gaia EDR3) contains results derived from 78 billion individual field-of-view transits of 2.5 billion sources collected by the European Space Agency's…
Gaia Early Data Release 3: The astrometric solution
L. Lindegren, S. A. Klioner, J. Hernández +94
Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in the magnitude range G = 3 to 21 based on observations collected by the European Space Agency Gai…
Gaia Early Data Release 3: Parallax bias versus magnitude, colour, and position
L. Lindegren, U. Bastian, M. Biermann +14
Gaia Early Data Release 3 (Gaia EDR3) gives trigonometric parallaxes for nearly 1.5 billion sources. Inspection of the EDR3 data for sources identified as quasars reveals that thei…
Gaia Early Data Release 3: Modelling and calibration of Gaia's point and line spread functions
N. Rowell, M. Davidson, L. Lindegren +18
Context: The unprecedented astrometric precision of the Gaia mission relies on accurate estimates of the locations of sources in the Gaia data stream. This is ultimately performed…
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
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-quali…
