The ICCUB Colloquia are talks given by world renowned speakers about cutting-edge topics in cosmology, astrophysics and particle and nuclear physics. The talks are directed to a diverse audience, including not only ICCUB members but also external researchers and graduate and master students.

ICCUB Colloquia are held monthly at the Physics Faculty of the University of Barcelona, headquarters of the ICCUB. Each colloquium is preceded by an informal welcome with coffee and biscuits in which assistants have the possibility to talk with the speaker. Young researchers are encouraged to meet with the speaker in an afternoon session.
