Research on Gravitation, Astrophysics, and Cosmology in Argentina and Brazil has reached a substantial degree of development. We believe, however, that the interaction between groups of both countries working in these areas is still not strong enough to undertake long-term, successful joint research programs. It was with the goal of stimulating collaboration that we started the series of Argentinian-Brazilian Meetings on Gravitation, Astrophysics, and Cosmology.
The first meeting was held in Foz do Iguaçu, Brazil, in October 2011, with the attendance of 76 researchers and students from Argentina and Brazil. The conference consisted in a number of invited review talks encompassing a wide and balanced range of topics, that offered a complete panorama of the research lines of both communities. The meeting closed with a round-table discussion. Participants could also present their work as posters.
The organization of the second meeting of the series aims at strengthening the links between both communities, and fully involving a larger number of researchers and students in the discussions. The scheme of the conference will change to include contributed talks, together with a few invited presentations by well-known specialists on topics of particular relevance. We as well intend to encourage the involvement of researchers from Brazil and Argentina in the Cherenkov Telescope Array Consortium (CTA, http://www.cta-observatory.org/), and to explore the applications in the fields of Astrophysics and Cosmology of the binational project Long Latin American Millimeter Array (LLAMA, http://www.iar.unlp.edu.ar/llama-web/).
