Binary Encodings of Non-binary Constraint Satisfaction Problems: Algorithms and Experimental Results

N. Samaras, K. Stergiou

A non-binary Constraint Satisfaction Problem (CSP) can be solved directly using extended versions of binary techniques. Alternatively, the non-binary problem can be translated into…

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: Hot-star radial velocities

R. Blomme, Y. Fremat, P. Sartoretti +38

The second Gaia data release, DR2, contained radial velocities of stars with effective temperatures up to Teff = 6900 K. The third data release, Gaia DR3, extends this up to Teff =…

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…
