An empirical model of the Gaia DR3 selection function
Tristan Cantat-Gaudin, Morgan Fouesneau, Hans-Walter Rix +11
Interpreting and modelling astronomical catalogues requires an understanding of the catalogues' completeness or selection function: objects of what properties had a chance to end u…
A new resonance-like feature in the outer disc of the Milky Way
Ronald Drimmel, Shourya Khanna, Elena D'Onghia +18
Modern astrometric and spectroscopic surveys have revealed a wealth of structure in the phase space of stars in the Milky Way, with evidence of resonance features and non-equilibri…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
Gaia Data Release 3: Catalogue Validation
C. Babusiaux, C. Fabricius, S. Khanna +40
The third gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly…
Gaia Data Release 3: Mapping the asymmetric disc of the Milky Way
Gaia Collaboration, R. Drimmel, M. Romero-Gomez +453
With the most recent Gaia data release the number of sources with complete 6D phase space information (position and velocity) has increased to well over 33 million stars, while ste…
The disturbed outer Milky Way disc
Paul J. McMillan, Jonathan Petersson, Thor Tepper-Garcia +9
The outer parts of the Milky Way's disc are significantly out of equilibrium. Using only distances and proper motions of stars from Gaia's Early Data Release 3, in the range |b|<10…
Revised extinctions and radii for 1.5 million stars observed by APOGEE, GALAH, and RAVE
Jie Yu, Shourya Khanna, Nathalie Themessl +4
Asteroseismology has become widely accepted as a benchmark for accurate and precise fundamental stellar properties. It can therefore be used to validate and calibrate stellar param…
Measuring the Streaming motion in the Milky Way disc with Gaia EDR3 +
Shourya Khanna, Sanjib Sharma, Joss Bland-Hawthorn +1
We map the 3D kinematics of the Galactic disc out to 3.5 kpc from the Sun, and within 0.75 kpc from the midplane of the Galaxy. To this end, we combine high quality astrometry from…
