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.
Spontaneous scalarization is an interesting phenomenon that black holes with a sufficiently large mass or charge spontaneously transit to a solution with
The Nobel Prize in Physics 2019 was awarded in one half to Michel Mayor and Didier Queloz "for the discovery of an exoplanet orbiting a solar-type star".
In the framework of the COST action MW-Gaia, related with the Gaia (ESA) mission, for which Gr@v member Alexandre Correia serves as MC member, a 3-days workshop on "Exoplanets in the era of Gaia" is being organised on 18-20 November 2019, at CAUP, Porto, Portugal. More info here.
In the framework of the COST action MW-Gaia, related with the Gaia (ESA) mission, for which Gr@v member Sonia Anton serves as MC member, a 3-days workshop on "Astrometry and gravitation - A dynamical view of the sky" is being organised on 4-6 December 2019, at the Observatoire de la Côte d’Azur, Mont Gros site, Nice, France.

The Kavli-RISE Summer School on Gravitational Waves took place at the Centre for Theoretical Cosmology, University of Cambridge, on September 23-27, 2019. C. Herdeiro was one of the invited Lecturers.
Pedro Cunha defended his PhD thesis with title "Shadows and gravitational lensing of Black Holes interacting with fundamental fields" on September 9th 2019, at IST-Lisbon. The panel, composed by Prof. Volker Perlick, Frederic Vincent, José Natário, Carlos Herdeiro (advisor) and José Lemos (president) unanimously attributed the highest classification of Approved with Distinction and Honour to an outstanding piece of work. Congratulations Pedro!
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
