On the Presence of Angular-Velocity Offsets in Disk Galaxies
Tomer Zimmerman, Lev Tal-Or, Roy Gomel
The well-known discrepancy in galactic rotation curves refers to the mismatch between observed rotational velocities and the velocities predicted by baryonic matter. In this study…
Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
Gaia Collaboration, A. Krone-Martins, C. Ducourant +398
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of " in the optical, ma…
Gaia Data Release 3: All-sky classification of 12.4 million variable sources into 25 classes
Lorenzo Rimoldini, Berry Holl, Panagiotis Gavras +31
Gaia DR3 contains 1.8 billion sources with G-band photometry, 1.5 billion of which with BP and RP photometry, complemented by positions on the sky, parallax, and proper motion. The…
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…
The Effects of Inertial Forces on the Dynamics of Disk Galaxies
Roy Gomel, Tomer Zimmerman
When dealing with galactic dynamics, or more specifically, with galactic rotation curves, one basic assumption is always taken: the frame of reference relative to which the rotatio…
