Gaia Data Release 2: Processing the spectroscopic data

P. Sartoretti, D. Katz, M. Cropper +50

The Gaia Data Release 2 contains the 1st release of radial velocities complementing the kinematic data of a sample of about 7 million relatively bright, late-type stars. Aims: This…

Gaia Data Release 3: Chemical cartography of the Milky Way

Gaia Collaboration, A. Recio-Blanco, G. Kordopatis +447

Gaia DR3 opens a new era of all-sky spectral analysis of stellar populations thanks to the nearly 5.6 million stars observed by the RVS and parametrised by the GSP-spec module. The…

Euclid preparation LXXIX. Using mock low surface brightness dwarf galaxies to probe Euclid Wide Survey detection capabilities

Euclid Collaboration, M. Urbano, P. -A. Duc +313

Local Universe dwarf galaxies can serve as both cosmological and mass assembly probes. Deep surveys have enabled the study of these objects down to the low surface brightness (LSB)…

Gaia Early Data Release 3: The Galactic anticentre

Gaia Collaboration, T. Antoja, P. McMillan +417

We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of the Milky Way structure and evolution. We used astrometric positions, proper…

The partition function of the two-matrix model as an isomonodromic tau-function

M. Bertola, O. Marchal

We consider the Itzykson-Zuber-Eynard-Mehta two-matrix model and prove that the partition function is an isomonodromic tau function in a sense that generalizes Jimbo-Miwa-Ueno's. I…

Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri

Gaia Collaboration, K. Weingrill, A. Mints +400

Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
