IV CosmoSul –

Cosmology and Gravitation in the Southern Cone

Description:

This workshop will focus on several aspects of cosmology and gravitation, including gravitational waves, the physics of the early universe and observational tests of the late-time cosmic acceleration.  Its primary goal is to foster new collaborations and long-lasting partnerships among the various cosmology and gravitation groups of Argentina, Brazil, Chile and Uruguay.

The program of the workshop will consist of invited plenary talks, oral presentations (20-30 min) and posters. There is no registration fee. 

This Workshop will be preceded by the “ICTP-Trieste/ICTP-SAIFR School on Open Problems in Cosmology“​. If​ you w​ould like​ to apply for the school​,​ please access http://www.ictp-saifr.org/cosmology17
