It's paper day! The first science paper with data from @vrubinobs.bsky.social's survey camera, the mighty LSSTCam, is a VERY quick turnaround of Rubin's observations thus far of interstellar comet 3I/ATLAS. ☄️ Chandler et al., submitted 🔭 A 🧵

Happy to announce that the line-detector.oca.eu website is now online! It allows the user to select the stellar type, [M/H], λ- range, and resolving power and the page returns: -purity of the line and minimum S/N required to detect it. -interactive plot to identify the lines in the spectra

C'est parti ! @euclid-france.bsky.social

Atelier Philo-Sciences "Temps des humains, temps des étoiles" à la médiathèque Meinau, samedi 15/03 à 10:30 avec @nfmartin1980.bsky.social, en partenariat avec @cnrs-alsace.bsky.social et les médiathèques de @strasbourg-eu.bsky.social : www.alsace.cnrs.fr/fr/evenement...

This review was an absolute joy to write. Thank you Amandine and @runningastronomer.bsky.social ! :)

The ESA #Gaia mission has delivered the best Milky Way maps to date and taken its last starlight before spacecraft retirement 🔭 www.esa.int/Science_Expl...

Jakub Podgorný, qui effectué sa thèse effectuée à l’Observatoire astronomique de Strasbourg @unistra.fr, vient d’obtenir le prestigieux prix national des thèses de doctorat en sciences naturelles en République Tchèque. Félicitations ! astro.unistra.fr/fr/2024/12/0...

Notre collègue @nfmartin1980.bsky.social était invité de @franceinter.bsky.social pour parler d'archéologie galactique. www.radiofrance.fr/franceinter/...

J’étais aujourd’hui sur @franceinter.bsky.social pour La Terre au Carré où nous avons discuté archéologie galactique avec ma collègue Alejandra Recio-Blanco. Un moment agréable d’échange ! www.radiofrance.fr/franceinter/...

Hello there! Are you on the job market? Do you love astrophysics? Then how about applying for one of our 3 open Research Fellow positions at the University of Surrey? One of them is with me! Find and study dwarf galaxies with Michelle! 🔭🧪 jobs.surrey.ac.uk/Vacancy.aspx...

Very happy to be visiting the Royal Observatory of Edinburgh today and giving a talk about the low-metallicity Milky Way this afternoon. And Scottish weather didn’t disappoint this morning!

Very happy to share my new paper on arxiv: arxiv.org/abs/2309.06137 releasing a catalogue of spectroscopic metallicities of VMP stars using the amazing Gaia DR3 RVS spectra. Did you know that there exists a lot of archival VMP spectra out there with no published parameters?

Very proud of this work, a huge collaborative effort from the Pristine team! It's great to finally see it out in the wild 🥳🤩🔭

The 23rd paper of the main series of papers from the Pristine survey is out! It's been a lot of work by a lot of people since Gaia's Data Release 3 came out. It's also the first Data Release from the survey and we publish catalogues for ~30+ million stellar metallicities.

Do you like stellar metallicities? If so, you’re in luck! The Pristine collaboration is about to release many 10s of millions of those on Friday, including more than 200,000 very metal-poor star (candidates)… Stay tuned!
