We will review recent attempts at modifying gravity at cosmological scales, largely motivated by the aim of providing a dynamical explanation for dark energy. We will see that it is quite challenging to construct infrared modifications of gravity that are both theoretically consistent and cosmologically viable. We will finally present some work of our group on effective nonlocal modifications...

After the first direct detection of gravitational wave we entered in the new era of gravitational wave astronomy. New kind of sources are expected to be found, and the future steps toward improved detectors' sensitivities will allow to extract physical information in a more and more accurate way.
I describe the status of current network of detectors, the more important sources of noise that...

The detection by LIGO of GW150914 marks the beginning of a new era in physics and astrophysics. I will review theoretical work that paved the way to observe such a gravitational-wave signal and discuss the results of the discovery focusing on its gravitational, astrophysical and fundamental physics aspects.
