New Frontiers in Strong Gravity


D. Blas (ICREA/IFAE), P. Figueras (Queen Mary University of London), S. Nissanke (University of Amsterdam), L. Stein (University of Mississippi), H. Witek (UIUC)

The highly nonlinear, strong-field regime of gravity holds the key to address long-standing puzzles in modern physics. These range from deeply theoretical questions concerning a consistent theory of quantum gravity and resulting modifications to general relativity, over the stability properties of black holes in traditional general relativity, to new insight into nuclear matter under extreme conditions in the context of neutron star and multimessenger astronomy.

In this two-week workshop we will bring together leading experts as well as junior scientists in these diverse research areas, to encourage communication and training across the fields and to foster new research collaborations

The number of participants is limited and we will notify accepted participants by 22 May 2024.

Bus transportation for participants will be organized by the Center. In particular, there will be a bus connection between Barcelona (including airport) and Benasque. The trip takes approximately 6 hours. Alternatively the trip by car takes approximately 3,5 hours from Barcelona, and 3,2 hours from Toulouse (connected by high-speed train to Paris) or Zaragoza (connected by high-speed train to Paris). The CCBPP center can also be reached with public transportation, using buses that depart from Zaragoza's (4 hours) and Barcelona's (6 hours) high speed train stations.
