This meeting has taken place yearly for two decades. It is organized jointly by a triangle: The Astroparticle and Cosmology Lab (APC) in Paris, the Higgs Centre for Theoretical Physics in Edinburgh, and the Perimeter Institute for Theoretical Physics in Waterloo, Canada
It is an informal meeting whose primary goal is to contrast novel theoretical ideas from fundamental physics with the cosmological arena, as well as novel ideas for measurements in the cosmological context with the possible theoretical models that can be tested.
For this, the meeting has ample time for discussions and interactions and few talks.
