Implementing the Gaia Astrometric Global Iterative Solution (AGIS) in Java [PDF]

open access: yes, 2011
This paper provides a description of the Java software framework which has been constructed to run the Astrometric Global Iterative Solution for the Gaia mission. This is the mathematical framework to provide the rigid reference frame for Gaia observations from the Gaia data itself.

Astrometry and Exoplanets: the Gaia Era, and Beyond [PDF]

open access: yes, 2010
The wealth of information in the Gaia catalogue of exoplanets will constitute a fundamental contribution to several hot topics of the astrophysics of planetary systems. I briefly review the potential impact of Gaia micro-arsec astrometry in several areas of exoplanet science, discuss what key follow-up observations might be required as a complement to ...

The Gaia Project - technique, performance and status [PDF]

open access: yesAstron.Nachr.329:875,2008, 2008
Gaia is a satellite mission of the ESA, aiming at absolute astrometric measurements of about one billion stars (all stars down to 20th magnitude, with unprecedented accuracy. Additionally, magnitudes and colors will be obtained for all these stars, while radial-velocities and spectral properties will be determined only for bright objects (V<17.5).

Fundamental Physics with GAIA [PDF]

open access: bronzeEAS Publications Series, 2002
The baseline of GAIA is the study of the formation and evolution of the Milky Way from astrometric and photometric measurements. The mission displays a remarkable versatility in its applications, including a significant impact in fundamental physics. In the following I will try to define the relationship between astrometry and
