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.

Celebrating Strong Gravity - 25 - 11 - 25

On November 25, 1915, Einstein presented the field equations of General Relativity to the Prussian Academy of Sciences. A hundred and ten years later, we celebrate the remarkable progress of the field of strong gravity — its many achievements, the 15th anniversary of the Aveiro Gr@v group (est. 2010), and a decade since the first detection of gravitational waves.
