Astrophysics and Cosmology
This group gathers researchers working on astrophysics and cosmology topics. It covers theoretical, computational and observational skills, potentiating synergies between them to tackle a number of problems of current interest in the field. The main research areas are the physics of white dwarfs, neutron stars and black holes, the equation of state of dense hadronic matter, radio astronomy, detection and characterisation of exoplanets, dynamics of stellar and planetary systems, celestial mechanics, computational astrophysics, interplay between particle and gravitational physics, the origin of dark matter, dark energy, inflation, and the baryon asymmetry.
