The French Action Thématique de Cosmologie et Galaxies (ATCG) organizes a national conference on Oct 12-14 2026 at the Institut d'Astrophysique de Paris (IAP) and Observatory of Paris (ObsPM) on galaxy formation and evolution, nearby galaxies, and Galactic archeology.

We particularly encourage researchers funded by the ATCG, students, postdocs, and young researchers in France or with ties to the French community to present their work. Registration is free of charge. We have limited funds to support travel to Paris for those giving presentations -- please ask when registering if needed.

Presentations will be in English and in-person only, i.e. not remotely.  We welcome both talk and poster submissions, and we include flash-talks for all poster presenters. 

Confirmed invited speakers: Sunayana Bhargava, Corentin Cadiou, Florent Mertens, Chervin Laporte and, Karina Voggel.

Key themes: 

• The first galaxies
• Chemical enrichment and primordial gas
• Statistical properties of galaxies
• Interaction between galaxies and their environment
• Galaxy groups and cluster
• Nearby galaxies
• Galactic archeology
• Star formation and the interstellar medium
• Stellar populations
• Galactic dynamics and dark matter
• Simulations
• AI, neural networks and data science
