The APC science is organised around five science teams, namely 4 thematics:
- High Energy Astrophysics;
- and one transversal: Theory.
The teams organize the common issues related to their thematic, e.g. define the priorities of the thematic science policy, the recruitment priorities and have a primary role in the scientific animation. They organize seminars, discussions, initiate new projects, welcome students for internship or Ph.D., and fund travel for general conferences. The teams have a specific annual budget and are lead by a responsible and its deputy.
