SILAFAE is a traditional event that gathers the Latin American community in High Energy, Cosmology and AstroParticle Physics, with the aim of discussing our current knowledge and the future perspectives in these areas.

The 12th edition was held in Lima, Peru (

Due to the Covid-19 pandemic, we are organizing a light-weight, online meeting that we are calling the 12¾th edition and planning a full in-person meeting in Ecuador in 2022.

In addition to the invited talks, we anticipate a reduced number of short contributed talks. Posters with pre-recorded talks and one session with flash presentations is planned as well.

We are also planning the creation of a Latin American Association for High Energy, Cosmology and Astroparticle Physics during SILAFAE with the goals to congregate and organize our community. Please find a proposal for the by-laws HERE.

There is no registration fee.
