Scientific Programme


The Brazilian School of Cosmology and Gravitation (BSCG) is a traditional international school about Cosmology and Gravitation for graduate students, young pos-docs and researchers in the field, which has been held in Brazil since 1978. Some of the speakers of the school were Evgeny Lifshitz, Bryce DeWitt, Yvone de Choquet-Bruhat, Rocky Kolb, Claudio Teitelboim, George Ellis, John Ellis, David Schram, George Smoot, Werner Israel, Larry Ford, Robert Brandenberger, Slava Mukhanov, Jorge Pullin, Luca Amendola, William Unruh, among many others. The visit of these outstanding scientists to Brazil played a fundamental role in the formation of research groups in Cosmology, Gravitation and Astrophysics in our country, and the implementation of many international scientific collaborations.

The 18th edition of the BSCG is dedicated to the 100th anniversary of the Friedmann cosmological solution. It will contain mini-courses focusing on the primordial and hot Universe, the physics of extreme energy scales near the cosmological singularity, present in the Friedmann solution, and its possible resolution in the context of quantum gravity approaches. There will also be advanced seminars concerning aspects of the late Universe, and the upcoming tensions of the standard cosmological model based on the Friedmann solution.

This edition of the school will also celebrate Mario Novello’s 80th anniversary, the founding-father of the BSCG, dedicating one day of the meeting, September 12, to seminars and talks in his honor. During this day we have already confirmed talks of 30 minutes plus 10 minutes of discussions by William Unruh, Alexei Starobinski, Alexander Dolgov, Viatcheslav Mukhanov, Nathalie Deruelle, Ignácio Bediaga, Nami Fux Svaiter, Ivano Soares, Carlos Romero, Júnior Toniato, Sérgio Jorás, Eduardo Bittencourt, and the former Minister of Science and Technology Roberto Amaral. In the following 4 days, September 13 to 16, 2022, the mini-courses of 4 lectures by Edward Kolb, Fabio Finelli, Antônio Pereira, Patrick Peter, and Suddhasattwa Brahma will take place, with 50 minutes for each lecture plus 15 minutes of discussions for each course. Completing these days, advanced seminars of 50 minutes plus 10 minutes of discussions will be held by Wendy Freedman, Leila Graef, Slava Mukhanov, and Jérôme Martin.

All days are divided in morning sections from 9 am until 12:30, with one coffee break of 20 minutes, and afternoon sections from 2:30 pm until 6:30 pm, with one coffee break of 20 minutes, with 40 minutes to visit the poster section, which will be exhibited in a room besides the main auditorium.

The courses are introductory to research activities in the area of Cosmology, Astrophysics, and Gravitation. The seminars are advanced. The participants are expected to be senior undergraduate students in Physics, Mathematics, Astronomy, or Engineering, graduate students and post-docs in Physics or Astronomy, and researchers in these areas.
