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…
Predictions of Gaia's prize microlensing events are flawed
Peter McGill, Andrew Everall, Douglas Boubert +1
Precision astrometry from the second Gaia data release has allowed astronomers to predict 5,787 microlensing events, with 528 of these having maximums within the extended Gaia miss…
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…
Completeness of the Gaia-verse I: when and where were Gaia's eyes on the sky during DR2?
Douglas Boubert, Andrew Everall, Berry Holl
The Gaia space mission is crafting revolutionary astrometric, photometric and spectroscopic catalogues that will allow us to map our Galaxy, but only if we know the completeness of…
Deflection of the hypervelocity stars by the dance of the Milky Way and Large Magellanic Cloud
Douglas Boubert, Denis Erkal, Alessia Gualandris
Stars slingshotted by the supermassive black hole at the Galactic centre will escape the Milky Way so quickly that their trajectories will be almost straight lines. Previous works…
