Completeness of the Gaia-verse IV: The Astrometry Spread Function of Gaia DR2
Andrew Everall, Douglas Boubert, Sergey E. Koposov +2
Gaia DR2 published positions, parallaxes and proper motions for an unprecedented 1,331,909,727 sources, revolutionising the field of Galactic dynamics. We complement this data with…
Completeness of the Gaia-verse III: using hidden states to infer gaps, detection efficiencies and the scanning law from the DR2 light curves
Douglas Boubert, Andrew Everall, Jack Fraser +2
The completeness of the Gaia catalogues heavily depends on the status of that space telescope through time. Stars are only published with each of the astrometric, photometric and s…
Completeness of the Gaia-verse II: what are the odds that a star is missing from Gaia DR2?
Douglas Boubert, Andrew Everall
The second data release of the Gaia mission contained astrometry and photometry for an incredible 1,692,919,135 sources, but how many sources did Gaia miss and where do they lie on…
Binary deviations from single object astrometry
Zephyr Penoyre, Vasily Belokurov, N. Wyn Evans +2
Most binaries are undetected. Astrometric reductions of a system using the assumption that the object moves like a single point mass can be biased by unresolved binary stars. The d…
The Tilt of the Local Velocity Ellipsoid as Seen by Gaia
A. Everall, N. W. Evans, V. Belokurov +1
The Gaia Radial Velocity Spectrometer (RVS) provides a sample of 7,224,631 stars with full six-dimensional phase space information. Bayesian distances of these stars are available…
seestar: Selection functions for spectroscopic surveys of the Milky Way
Andrew Everall, Payel Das
Selection functions are vital for understanding the observational biases of spectroscopic surveys. With the wide variety of multi-object spectrographs currently in operation and be…
