Reuven Opher was a leading astrophysicist and cosmologist working in Brazil from 1979 through 2014. He established two successful series of workshops: the “Nova Física no Espaço”, which was held in Portuguese in an informal setting and directed to the Brazilian community, and the “Challenges of New Physics in Space”, an international workshop where renowned researchers were invited to present the state-of-the-art in different fields of Astrophysics and Cosmology. The last edition was the XIIIth workshop held at the ICTP-SAIFR in 2016.

In addition to the invited talks, there will be space for posters with pre-recorded talks and one session with flash presentations is planned as well.

This workshop, named after Reuven Opher, will continue his efforts to showcase the work of the Brazilian community in the fields related to Cosmology, Gravity and Astrophysics.
