A New kinematic model of the Galaxy: analysis of the stellar velocity field from \emph{Gaia} Data Release 3
V. S. Akhmetov,Beatrice Bucciarelli,Mariateresa Crosta,Mario G. Lattanzi,Alessandro Spagna,Paola Re Fiorentin,Elena Yu. Bannikova +6 more
TL;DR: In this article , the Taylor decomposition of the velocity field up to second order for 18 million high luminosity stars (i.e., young OB, giants and subgiants) from the Gaia DR3 data is carried out.

Physical Reference Frames and Astrometric Measurements of Star Direction in General Relativity \\I. Stellar Aberration
TL;DR: In this article, the authors set the level of reciprocal consistency of two relativistic models, GREM and RAMOD (Gaia, ESA mission), in order to guarantee a physically correct definition of light direction to a star.
Post-Newtonian gravity and Gaia -like astrometry Effect of PPN γ uncertainty on parallaxes
A. G. Butkevich,Alberto Vecchiato,Beatrice Bucciarelli,Mario Gai,Mariateresa Crosta,Mario G. Lattanzi +5 more
TL;DR: In this paper , the effects of a small deviation in the post-Newtonian (PPN) parameter γ from the value predicted by general relativity on the parallax estimations in Gaia-like astrometry were calculated analytically and numerically.
On the principle of Astrometric Gravitational Wave Antenna
Mariateresa Crosta,Mario G. Lattanzi,C. Le Poncin-Lafitte,Mario Gai,Qin Zhaoxiang,Alberto Vecchiato +5 more
TL;DR: In this paper , the authors proposed a novel concept for a gravitational wave antenna in space that uses close pairs of point-like sources as natural sensors to record and characterize the very tiny variations in angular separations induced by a passing gravitational wave, thus operating complementary to linear arm detectors and enabling to gain informations on the gravitational wave incoming direction.

Astrometric observable and relativistic astrometric catalogues
TL;DR: In this article, the authors describe a way to compare current relativistic astrometric models accurate to the micro-arcsecond level from which a catalogue will be deduced.
