Magnetar counterparts, kinematics and birth sites with HST and JWST
A. A. Chrimes, J. D. Lyman, A. J. Levan +7
Magnetars are highly magnetised, isolated neutron stars with uncertain formation channels. They comprise a potentially significant fraction of the young neutron star population in…
Searching for Isolated Black Hole Candidates within 15 pc of the Solar System in Gaia DR3
Abdurakhmon Nosirov, Cosimo Bambi, Leda Gao +4
Theoretical models predict that the Galaxy hosts - black holes formed from the complete gravitational collapse of heavy stars and that most of these black holes are iso…
HD 7977 and its possible influence on Solar System bodies
Piotr A. Dybczyński, Małgorzata Królikowska, Przemysław Bartczak +5
In the latest Gaia third data release one can find extremely small proper motion components for the star HD 7977. This, together with the radial velocity measurement lead to the co…
Strömgren photometric metallicity of the Small Magellanic Cloud stars using Gaia DR3-XP spectra
Abinaya O. Omkumar, Smitha Subramanian, Maria-Rosa L. Cioni +1
Observational studies have identified several sub-structures in different regions of the Magellanic Clouds, the nearest pair of interacting dwarf satellites of the Milky Way. By st…
Constraining the initial conditions of NGC 2264 using ejected stars found in Gaia DR2
Christina Schoettler, Richard J. Parker, Jos de Bruijne
Fast, ejected stars have been found around several young star-forming regions, such as the Orion Nebula Cluster (ONC). These ejected stars can be used to constrain the initial dens…
Fine structure in the luminosity function in young stellar populations with Gaia DR2
Difeng Guo, Alex de Koter, Lex Kaper +2
A pioneering study showed that the fine structure in the luminosity function (LF) of young star clusters contains information about the evolutionary stage (age) and composition of…
Digitization and astrometric calibration of Carte du Ciel photographic plates with Gaia~DR1
K. Lehtinen, T. Prusti, J. de Bruijne +6
We want to study whether the astrometric and photometric accuracies obtained for the Carte du Ciel plates digitized with a commercial digital camera are high enough for scientific…
Gaia Data Release 2. Calibration and mitigation of electronic offset effects in the data
N. C. Hambly, M. Cropper, S. Boudreault +30
The European Space Agency Gaia satellite was launched into orbit around L2 in December 2013. This ambitious mission has strict requirements on residual systematic errors resulting…
A Gaia study of the Hyades open cluster
Stella Reino, Jos de Bruijne, Eleonora Zari +2
We present a study of the membership of the Hyades open cluster, derive kinematically-modelled parallaxes of its members, and study the colour-absolute magnitude diagram of the clu…
The intricate Galaxy disk: velocity asymmetries in Gaia-TGAS
T. Antoja, J. de Bruijne, F. Figueras +3
We use the Gaia-TGAS data to compare the transverse velocities in Galactic longitude (coming from proper motions and parallaxes) in the Milky Way disk for negative and positive lon…
Gaia Data Release 1: Astrometry - one billion positions, two million proper motions and parallaxes
L. Lindegren, U. Lammers, U. Bastian +80
Gaia Data Release 1 (Gaia DR1) contains astrometric results for more than 1 billion stars brighter than magnitude 20.7 based on observations collected by the Gaia satellite during…
On-orbit performance of the Gaia CCDs at L2
C. Crowley, R. Kohley, N. C. Hambly +19
The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mi…
Gaia Data Release 1. Summary of the astrometric, photometric, and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +5
At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magni…
Kinematics of symmetric Galactic longitudes to probe the spiral arms of the Milky Way with Gaia
T. Antoja, S. Roca-Fabrega, J. de Bruijne +1
We model the effects of the spiral arms of the Milky Way on the disk stellar kinematics in the Gaia observable space. We also estimate the Gaia capabilities of detecting the predic…
Detecting stars, galaxies, and asteroids with Gaia
J. H. J. de Bruijne, M. Allen, S. Azaz +3
(Abridged) Gaia aims to make a 3-dimensional map of 1,000 million stars in our Milky Way to unravel its kinematical, dynamical, and chemical structure and evolution. Gaia's on-boar…
Astrometry of brown dwarfs with Gaia

Europe's Gaia spacecraft will soon embark on its five-year mission to measure the absolute parallaxes of the complete sample of 1,000 million objects down to 20 mag. It is expected…
An Analytical Model of Radiation-Induced Charge Transfer Inefficiency for CCD Detectors
Alexander Short, Cian Crowley, Jos H. J. de Bruijne +1
The European Space Agency's Gaia mission is scheduled for launch in 2013. It will operate at L2 for 5 years, rotating slowly to scan the sky so that its two optical telescopes will…
Science performance of Gaia, ESA's space-astrometry mission
