Relative astrometry in an annular field
Mario Gai, Alberto Vecchiato, Alberto Riva +4
Background. Relative astrometry at or below the micro-arcsec level with a 1m class space telescope has been repeatedly proposed as a tool for exo-planet detection and characterizat…
Astrometric precision tests on TESS data
Mario Gai, Alberto Vecchiato, Alberto Riva +5
Background. Astrometry at or below the micro-arcsec level with an imaging telescope assumes that the uncertainty on the location of an unresolved source can be an arbitrarily small…
Theia : science cases and mission profiles for high precision astrometry in the future
Fabien Malbet, Lucas Labadie, Alessandro Sozzetti +11
High-precision astrometry well beyond the capacities of Gaia will provide a unique way to achieve astrophysical breakthroughs, in particular on the nature of dark matter, and a com…
Gaia Data Release 3: The first Gaia catalogue of variable AGN
Maria I. Carnerero, Claudia M. Raiteri, Lorenzo Rimoldini +15
One of the novelties of the Gaia-DR3 with respect to the previous data releases is the publication of the multiband light curves of about 1 million AGN. The goal of this work was t…
Differential Astrometry with Gaia: Investigating relativistic light deflection close to Jupiter
U. Abbas, B. Bucciarelli, M. G. Lattanzi +5
In this paper we develop a differential astrometric framework that is appropriate for a scanning space satellite such as Gaia. We apply it to the first of the GAREQ fields, which i…
Gaia Data Release 3: Catalogue Validation
C. Babusiaux, C. Fabricius, S. Khanna +40
The third gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly…
