Alexandre Correia ceases role as group coordinator

Alexandre Correia, Professor at Coimbra University, ended his term as scientific coordinator of the Gravitational Geometry and Dynamics Group (informally dubbed Gr@v) of CIDMA on 16 December 2019. Prof. Correia will cease to be a full member of CIDMA at the end of 2019 by virtue of his move to Coimbra University. The group is very grateful for his leadership. The new elected scientific coordinator is Carlos Herdeiro.

Alexandre Correia on the 2019 Nobel Physics Prize

Alexandre Correia, Gr@v member and Professor at Coimbra University, gave an outreach talk on the part of the 2019 Nobel Physics Prize awarded for the discovery of the first exoplanets. Not only Professor Correia is a working scientist on the field, but he also worked, as a post-doc, in the group of the two laureates, Michel Mayor and Didier Queloz. A knowledgeable and entertaining account!

Quasinormal modes of neutron stars in R^2 gravity

Event type
In this talk we will discuss the quasinormal modes of neutron stars in modified theories of gravity, in particular, in R^2 gravity. In this model, in addition to the space-time and fluid degrees of freedom that are present in General Relativity, we naturally find a (massive) scalar field.
