1. Appel à Contribution : Nominations Médailles CNRS
—————————————————————————————-
Chaque année, dans le cadre de l’action “Talents CNRS”, l’attribution des médailles du CNRS célèbre les chercheurs et chercheuses et les agents qui contribuent de manière exceptionnelle au dynamisme et à la renommée de l’institution et de la recherche en France (l’appartenance des candidats aux corps du CNRS n’est pas un pré-requis).
Lors de sa session d’automne, la Section 19 propose à l’INSU des candidates et candidats pour les médailles du CNRS. Elle sollicite les programmes nationaux d’astronomie-astrophysique pour des propositions pour ces médailles.
L’ATCG met en place à cette occasion un formulaire afin de collecter vos propositions: https://sondage.osupytheas.fr/index.php/141345?lang=fr
Vous êtes invité à le remplir tout au long de l’année, et avant le 19 septembre pour les nominations de cette année. Le CES de l’ATCG étudiera les propositions et sélectionnera les candidates et candidats à faire remonter à la Section 19 chaque année généralement avant octobre.

2. Appel à Projet 2026 de l’ASNum (rappel)
—————————————————————————————-
L’Action Spécifique Numérique (ASNum) propose de soutenir plusieurs types d’actions autour de l’astrophysique numérique en 2026 :
- l’organisation de colloques et d’ateliers d’échanges sur des méthodes en numérique et analyse de données
- l’organisation de réunions de travail pour le développement de codes communautaires et l’exploitation des infrastructures de calcul
- l’organisation de formations à l’utilisation d’infrastructures de calcul, de librairies scientifiques, de codes communautaires
- la participation à des réunions et conférences en lien avec le calcul scientifique tant HPC que HPDA
Le CS de l’ASNum demande aux porteurs d’estimer l’empreinte carbone de leur projet (déplacements, hébergements, achats…) avec l’outil BGES AAP de l’INSU, et d’en fournir la synthèse (tableau). Les demandes doivent être envoyées au plus tard le 18 septembre 2025 à demandeasn@services.cnrs.fret aussi être adressées en cc au directeur d’unité du porteur du projet.
Le texte de l’AO, le formulaire et l’outil de calcul de l’empreinte carbone sont disponible sur ce lien: https://cloud.oca.eu/index.php/s/Dpfc2fcbgC35DcA

3. WST-France 2026: French meeting of the Wide-field Spectroscopic Telescope, March 25-27, 2026, Nice (France) – 1st announcement
—————————————————————————————-
WST (https://www.wstelescope.com/) is an ambitious facility that will be dedicated to spectroscopic surveys. The current baseline foresees a 12-m main mirror, with parallel operation of a large field-of-view (3 sq. degrees) and high multiplex (30,000 and 2,000) multi-object spectrograph facility with both low- and high-resolution modes (MOS), along with a giant panoramic (3 x 3 sq. arcmin) integral field spectrograph (IFS). These characteristics place WST far ahead of existing and planned MOS and IFS facilities: it will fill a crucial gap in the world-wide astronomical landscape, enabling transformative science in the areas of cosmology; galaxy assembly, evolution, and enrichment, including our own Milky Way; the origin of stars and planets; time-domain and multi-messenger astrophysics.
The WST consortium has recently been funded through the Horizon Europe framework to carry out a comprehensive three-year concept study. We aim to propose WST to ESO as the next large program after ELT completion. The proposal, according to the Expanding Horizons ESO initiative (see https://next.eso.org/), is due in June 2027.
France, with CNRS and CEA, is leading the WST consortium and has many key roles, both scientific and technological. Although the facility is foreseen for 2040+, the decision will happen very soon, and thus it is very timely to discuss the strategic role our community can play in such an ambitious project.
The meeting has different aims:
• to inform the broader French community (CNRS INSU & IN2P3, CEA, Universities) about WST and its unique capabilities, showing its potential for breakthrough science and illustrating current science driversto stimulate French researchers to join the team and propose new science cases
• to discuss the important synergies with upcoming ground- and space-based facilities
• to discuss the challenges of new technologies, big data, and possible upgrades with respect to the baseline
Specific topics include:
• CosmologyGalaxy formation, evolution, enrichment
• The MW, Local Group Galaxies, and galactic archaeology
• The formation of stars and planets
• The variable Universe
• Multi-messenger astrophysics
• Synergies with ground- and space-based facilities
• Big data challenges
• New technologies
The meeting will take place in « Le Saint Paul », close to the Nice city center (harbour), March 25-27 2026

4. RAMSES SNO days, November 24-27, 2025, Paris (France) – 2nd announcement
—————————————————————————————-
This meeting will be an opportunity for the RAMSES community to gather and discuss recent code developments as well as the latest scientific results and applications. We also welcome participants from outside the SNO, who will be able to learn more about both the research carried out with RAMSES and the way the SNO operates.
The RAMSES SNO is pleased to announce its third RAMSES SNO days.
The “RAMSES SNO” is a CNRS initiative to support RAMSES’ use and development within our astrophysics community. Jérémy Blaizot (Lyon) is leading this effort, along with Yohan Dubois (Paris), Matthias González (Saclay), Pierre Ocvirk (Strasbourg), Amandine Le Brun (Meudon), and Sebastien Peirani (Nice).
We’re planning this meeting from November 24th to 27th at Université Paris Cité (Paris). The meeting will resemble a French mini RAMSES User Meeting, with the addition of a presentation of the SNO objectives and activities.
More details regarding the program and venue will follow soon, but please save these dates. While we’ll offer online access to the meeting, we strongly encourage you to attend in person to foster community interaction.
Where : Université Paris Cité, campus Grands Moulins – Paris
When : Nov. 24-27
Limited Capacity : 50 participants max
Who can attend : anyone (PhD student, postdoc, staff) working in a research institute
Registration deadline : Sept. 14

—————————————————————————————-
The Atacama Large Aperture Submillimeter Telescope (AtLAST) is a concept for a wide-field of view (1-2 square degrees) 50-meter telescope working in the sub/millimeter at 5000m. With strong synergies with IRAM, SKA, and ALMA, and much to learn from these facilities, AtLAST will also revolutionize astronomy by providing deep and wide field-of-view observations of the millimeter and sub-millimeter sky.
Following the recommendations of the A&A prospective, in May 2025, we organised a 3-day workshop in Paris gathering 85 participants to discuss the current status of the AtLAST project, its scientific potential, gauge France’s potential interest and role in joining/supporting AtLAST, leverage on the french know-how in instrumentation and data reduction/analysis, and take into account the environmental and societal considerations. The meeting fostered extensive discussions (a summary of them is available at the following link: https://atlast-fr-days.sciencesconf.org/?lang=en), and the official involvement of many new French colleagues in the AtLAST working groups. This marks a significant boost to French representation in the project!
To build on the momentum created by this workshop, we have launched the French AtLAST newsletter, designed to maintain an up-to-date list of people within the French community interested in AtLAST, share important information about AtLAST and related topics, and provide a channel for you to share relevant news with the community. We plan to issue this newsletter every two months.
To subscribe, please use this link: https://listes.services.cnrs.fr/wws/subscribe/atlast-fr. We also strongly encourage you to register for the general AtLAST newsletter: https://www.atlast.uio.no/about/contact/index.html.
