Cosmology with gravitational waves

Nicola Tamanini (CEA Saclay)

Cosmology lunch

There are two circumstances in which the hidden basic fabric of the Universe is violently shaken and unveiled: in the enormous temperatures and densities of the Hot Big Bang and during the extreme collapse to form a black hole. CTC focuses on mathematical theories of these pivotal physical events, confronting them with observational data to gain new insight into the fundamental structure of the Universe and its origin. As well as supporting fellows and visiting professors, CTC's activities include hosting timely workshops and international conferences on frontier topics in cosmology.

For the first time, scientists have directly detected gravitational waves, ripples in the spacetime fabric of our universe predicted by Einstein's theory of general relativity. This type of radiation is generated by the violent dynamics of massive and compact astrophysical ...more »

Numerical simulations of Einstein’s equations of general relativity provided the first concrete evidence that the weak cosmic censorship conjecture can be violated in five-dimensional asymptotically flat spacetimes, where the simulations show that singularities can generically ...more »
