Presentation

The next biennial conference of the Thematic Action "Physics and Chemistry of the  Interstellar Medium" (PCMI) will take place in Toulouse, from November 16 to 19, 2026.

The PCMI Thematic Action is a CNRS/INSU project-based program also supported by CNRS/INP, CNRS/INC, CNES and CEA (www.pcmi.cnrs.fr). It animates research between physicists, chemists and astrophysicists to progress in the understanding of the interstellar and circumstellar environments of our galaxy and other galaxies.

Three major questions motivate the program:

• (1) the formation of large interstellar structures and their link to star and planet formation,
• (2) the role of the interstellar medium in the evolution of our galaxy and nearby and distant galaxies, and
• (3) the role of the cycling of matter between phases in the growth of molecular complexity

The conference will be held in person in Toulouse. To be inclusive with non-french speakers, the presentations will be in english.
