Cambridge School on Gravitational Waves
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 Fernandes moves to Queen Mary
Pedro Fernandes, a student that graduated from IST-Lisbon, after doing his Master thesis under the supervision of C. Herdeiro and E. Radu on "Spontaneous Scalarization of Charged Black Holes" is moving to Queen Mary and Westfield College, University of London, where he obtained a scholarship for pursuing his Ph.D. studies. Congratulations Pedro!

Gravitational lensing provides an important probe of the background geometry.
In this talk, I discuss light propagation on non-Lorentzian backgrounds which
arise in two different contexts. Firstly, we consider optical geometry, which
is a formalism in 3-space for light propagation in Lorentzian spacetimes:
Pedro Cunha PhD defense
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!
Gr@v students visit Brazil
Gr@v Ph.D. students Alexandre Pombo, João Oliveira and Jorge Delgado visited Belém, Brazil as members of the FunFiCO Marie Curie RISE project. Their visit coincided with the VII Amazonian Workshop on Gravity and analogue models, where they presented their work, and the Amazonian High Studies School in Theoretical Physics where they attended courses on Numerical Relativity and Gravitational Lensing.
FunFiCO mid term meeting
The Marie Curie RISE project FunFiCO, led by Aveiro University, had its mid term meeting on July 13th 2019 in Valencia. It was a very successful assessment of all activities so far.
At GR22
Current and former Gr@v members met at the 22nd International Conference on General Relativity and Gravitation (GR22) in Valencia, Spain. Great talks and great discussions!
On the Physical Review Letters cover
The paper "Spontaneously Scalarized Kerr Black Holes in Extended Scalar-Tensor–Gauss-Bonnet Gravity" published in Physical Review Letters (PRL), authored by Gr@v members Pedro Cunha and Eugen Radu (co-authored by Carlos Herdeiro from IST-Lisbon), was selected to feature on the cover of the 3rd July 2019 issue of PRL.
Suppressing GR deviations with rotating black holes in PRL
In a paper published in Physical Review Letters, Gr@v researchers Pedro Cunha and Eugen Radu (in collaboration with Carlos Herdeiro from IST-Lisbon) provide a new insight on how spin could mask non-GR features in astrophysical black holes.
100 years of light bending
On May 29th 1919 Eddington and Cottingham measured the position of stars near the sun during a total eclipse observed at the island of Príncipe, off the west African coast. Their results, together with the ones of another expedition undertaken by Crommelin and Davidson to Sobral (Brazil), were announced on November 6th 1919 and confirmed the General Theory of Relativity. This openned a new era in our understanding of gravity, space, time and matter... and made Einstein world famous.
