Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds

Gaia Collaboration, X. Luri, L. Chemin +417

We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…

Gaia Data Release 3: The extragalactic content

Gaia Collaboration, C. A. L. Bailer-Jones, D. Teyssier +444

The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epo…
