Gr@v members C. Herdeiro and E. Radu, were two of the speakers of the Mini-workshop on "Black holes and symmetries" at the Instituto de Física, Pontifica Universidad Católica Valparaíso, Chile. The workshop was organised by Olivera Moskovic and Dumitru Astefanesei. The other speaker was Marc Henneaux from the Université Libre de Bruxelles, Belgium.
In this work, we study cosmological and astrophysical applications of the recently proposed generalized hybrid metric-Palatini gravity theory, which combines features of both the metric and th
Nelson Eiró visited Gr@v just before successfully defending his M.Sc. thesis on "Strong lensing of light and shadow of a Black Hole surrounded by a heavy accretion disk", at IST-Lisbon, supervised by C. Herdeiro and P. Cunha. This visit coincided with the beginning of a long term visit by Aichen and Ruyong Li, both graduates from Beijing University of Technology.
Nico Sanchis-Gual and Nuno Santos visited Gr@v. Nico gave a seminar on "Non-linear dynamics of spinning bosonic stars: formation and stability". Nuno, an IST graduate, will join Gr@v as a PhD student in 2020, having been the top ranked candidate in the 2019 Individual FCT grant call in the Physics panel.
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.

I present a review on combined numerical and analytical efforts to construct "geon"-type solutions of the Einstein equations. Geons are time periodic - hence non-radiating - and spatially localized objects.
