ESA Voyage 2050 white paper -- Faint objects in motion: the new frontier of high precision astrometry
F. Malbet, U. Abbas, J. Alves +28
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole
The Event Horizon Telescope Collaboration
When surrounded by a transparent emission region, black holes are expected to reveal a dark shadow caused by gravitational light bending and photon capture at the event horizon. To…
Gaia Data Release 1, Pre-processing and source list creation
C. Fabricius, U. Bastian, J. Portell +1
The first data release from the Gaia mission contains accurate positions and magnitudes for more than a billion sources, and proper motions and parallaxes for the majority of the 2…
The Tycho-Gaia astrometric solution. How to get 2.5 million parallaxes with less than one year of Gaia data
Daniel Michalik, Lennart Lindegren, David Hobbs
Context. The first release of astrometric data from Gaia will contain the mean stellar positions and magnitudes from the first year of observations, and proper motions from the com…
Joint astrometric solution of Hipparcos and Gaia: A recipe for the Hundred Thousand Proper Motions project
Daniel Michalik, Lennart Lindegren, David Hobbs +1
The first release of astrometric data from Gaia is expected in 2016. It will contain the mean stellar positions and magnitudes from the first year of observations. For more than 10…
Improving distances to nearby bright stars: Combining astrometric data from Hipparcos, Nano-JASMINE and Gaia
Daniel Michalik, Lennart Lindegren, David Hobbs +2
Starting in 2013, Gaia will deliver highly accurate astrometric data, which eventually will supersede most other stellar catalogues in accuracy and completeness. It is, however, li…
