Cosmology

Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.

For our latest developments/activities in this area, please see the listing below.

Workshop in honour of Yves Brihaye

A two days workshop "Exact solutions in classical field theory: Solitons, black holes and bosons stars", that will take place on 2-3 June will honour the work of Yves Brihaye, former head of the Research Unit of Theoretical and Mathematical Physics and currently Professor Emeritus in the Unit Physics of the Univers,  Fields and Gravitation. As long time collaborators, E. Radu and C. Herdeiro are two of the invited speakers of the workshop.
