The late-time speed up of the Universe: from GR to modified gravity

Mariam Bouhmadi-López

We will present  several proposals  to describe the late-time acceleration of the  universe within the framework of general relativity and beyond it. In some of these models,  we will see how the cosmological perturbations behave and how well they fit the data. If time allows, we will as well discuss dark energy related singularities.
