Alessandra Silvestri Group - The Late Universe
We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.
With the evolution of the universe spanning a vast range of energies and scales, cosmological observables can shed light on virtually any particle physics model as well as on any theory of gravity.
Our passion and interests are in using the array of cosmological data available to us to test fundamental physics. Through the past years, we have been involved both in theoretical and observational aspects of this endeavor, with a particular focus on tests of gravity on cosmological scales.
We are a very active part of the ESA Euclid mission, and have started a program on Gravitational Waves Cosmology in collaboration with the GRAPPA (UvA) gravitational waves group.
