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…
Gaia kinematics reveal a complex lopsided and twisted Galactic disc warp
M. Romero-Gómez, C. Mateu, L. Aguilar +2
There are few warp kinematic models of the Galaxy able to characterise structure and kinematics. These models are necessary to study the lopsidedness of the warp and the twisting o…
Gaia Data Release 2. Summary of the contents and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
Gaia Data Release 2: Catalogue validation
F. Arenou, X. Luri, C. Babusiaux +36
The second Gaia data release (DR2), contains very precise astrometric and photometric properties for more than one billion sources, astrophysical parameters for dozens of millions,…
Gaia Data Release 2: Properties and validation of the radial velocities
D. Katz, P. Sartoretti, M. Cropper +51
For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…
Rings, spirals and manifolds
E. Athanassoula, M. Romero-Gomez, J. J. Masdemont
Two-armed, grand design spirals and inner and outer rings in barred galaxies can be due to orbits guided by the manifolds emanating from the vicinity of the L1 and L2 Lagrangian po…
Rings and spirals in barred galaxies. I Building blocks
E. Athanassoula, M. Romero-Gomez, J. J. Masdemont
In this paper we present building blocks which can explain the formation and properties both of spirals and of inner and outer rings in barred galaxies. We first briefly summarise…
The role of the unstable equilibrium points in the transfer of matter in galactic potentials
M. Romero-Gomez, J. J. Masdemont, C. Garcia-Gomez +1
We study the role of the unstable equilibrium points in the transfer of matter in a galaxy using the potential of a rotating triaxial system. In particular, we study the neighbourh…
