Finding out about Gaia at #EAS2025Cork! ☄️
Just announced: Gaia DR4 will be released in December 2026!
The fraction of simulated clusters we recover (upper panel) compared against a dust map (lower panel.) Dust is clearly a major hindrance to seeing open clusters with Gaia.
The detectability of young clusters (upper panel) and old clusters (lower panel) in the anticentre of our galaxy. Grey points show real clusters. It's clear that there's a huge void where we're not sensitive enough to say if there are more old clusters.
The detectability of old clusters, shown a different way. The two most distant catalogued clusters in the anticentre (Saurer 1 & Berkeley 29) appear to simply be lucky detections, as they sit in a small (not so reddened) part of the anticentre.
General trends in cluster detectability in the region as a function of various parameters. Mass, age, extinction, and distance are the biggest culprits.
How many open clusters could be hiding at the edge of our galaxy? 🔭☄️🧪 #galactic
Our new paper out today (A&A, accepted) pioneers a new way to test the completeness of cluster catalogues built with @esa.int's Gaia mission!
The 5 year mission plan for @nasaromantelescope.bsky.social summarized in an easy to read press release with some snazzy graphics. Which part are you most excited about? #NASARoman #LongLiveRoman

Gaia spacecraft in space in front of the Milky Way galaxy
Today we say goodbye to ESA’s Milky Way-mapper Gaia! The Gaia spacecraft has completed its sky-scanning and will be switched off this morning.

Hilariously, they used AI to generate realistic-looking webpages that have many many many links and can trap AI scraping bots in place:
The disappearance of Gaia
I am an astronomer/data scientist and would like to keep in touch with colleagues and eager to exchange on new Astro topics

Your feelings are very valid. I would be very cautious. Your affirmation is not legally correct, the context is far more complex, and it is not difficult to connect the dots. You have people at the institute with expertise, they can support.
Le satellite Gaia vient de faire ses dernières observations hier, après avoir observé 2 milliards d'astres! Cet instrument, dont on ne parle pas assez, est une véritable révolution pour l'astronomie. Ça vous dit d'en savoir plus et de connaître les principaux résultats?

Thank you. Glad it is useful 😄
