Gregorio Carullo visits Perimeter Institute

Strong member Gregorio Carullo visited Perimeter Institute for three weeks in June, hosted by Prof. Luis Lehner and the Gravity group.

During the visit, he delivered a seminar titled "Have we observed multiple quasinormal modes yet?", initiating fruitful collaborations on modelling black hole ringdown beyond General Relativity, and nonlinear effects in quasinormal modes excitation.
