Gaia Data Release 3. Catalogue validation [PDF]

open access: yesAstronomy & Astrophysics, 2022
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 two billion sources.

GAIA-1: A Generative World Model for Autonomous Driving [PDF]

open access: yesarXiv.org, 2023
Autonomous driving promises transformative improvements to transportation, but building systems capable of safely navigating the unstructured complexity of real-world scenarios remains challenging.

Improving the open cluster census. II. An all-sky cluster catalogue with Gaia DR3 [PDF]

open access: yesAstronomy & Astrophysics, 2023
Data from the Gaia satellite are revolutionising our understanding of the Milky Way. With every new data release, there is a need to update the census of open clusters. We aim to conduct a blind, all-sky search for open clusters using 729 million sources

Parameters of 220 million stars from Gaia BP/RP spectra [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2023
We develop, validate and apply a forward model to estimate stellar atmospheric parameters (Teff, log g and [Fe/H]), revised distances and extinctions for 220 million stars with XP spectra from Gaia DR3.

Gaia Early Data Release 3 [PDF]

open access: yesAstronomy & Astrophysics, 2021
Context. Since July 2014, the Gaia mission has been engaged in a high-spatial-resolution, time-resolved, precise, accurate astrometric, and photometric survey of the entire sky. Aims.

بررسی و پردازش دیداری تاب‌آوری شهری با تکنیک PROMETHEE- GAIA (موردمطالعه: شهر ایلام) [PDF]

open access: yesجغرافیا و مخاطرات محیطی, 2022
شهرنشینی به‌عنوان برترین شکل سکونت­گاه انسانی، ارتقای پایداری و تاب­آوری آن، یک اولویت است؛ لذا مطالعات تاب­آوری شهری و نحوه سنجش آن در شهرها اهمیت می‌یابد. این در حالی است که با وجود پیشرفت­های مهم در سال­های اخیر در این زمینه، روش­های موجود برای اندازه­

Gaia Data Release 2 [PDF]

open access: yesAstronomy & Astrophysics, 2018
Context. For Gaia DR2, 280 million spectra collected by the Radial Velocity Spectrometer instrument on board Gaia were processed, and median radial velocities were derived for 9.8 million sources brighter than GRVS = 12 mag. Aims.

Gaia EDR3 view on galactic globular clusters [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
We use the data from Gaia  Early Data Release 3 (EDR3) to study the kinematic properties of Milky Way globular clusters. We measure the mean parallaxes and proper motions (PM) for 170 clusters, determine the PM dispersion profiles for more than 100 ...

Binaries masses and luminosities with Gaia DR3 [PDF]

open access: yesA&A 678, A19 (2023), 2023
The recent Gaia third data release (DR3) has brought some new exciting data about stellar binaries. It provides new opportunities to fully characterize more stellar systems and contribute to enforce our global knowledge of stars behaviour. By combining the new Gaia non-single stars catalog with double-lined spectroscopic binaries (SB2), one can ...
