Strong Gravity

The group's research on strong gravity involves finding analytical and numerical solutions of Einstein's theory of general relativity, and many of its extensions, either in vacuum or coupled to various types of matter. For our latest developments/activities in this area, please see the listing at the end of this article.

The prime examples of (relativistic) strong gravitational systems are Black Holes. They are truly unifying objects of all physics. The understanding of their formation and dynamics requires the laws of all four fundamental forces, and their physics is relevant not only for astrophysics and cosmology but for a variety of topics within high energy physics.

See here a movie made by the COST action `Black holes in a violent universe', in which our group participates, for a visual overview of different types of black holes.

RISE coordinator's day 2018

A team from Aveiro University composed by Tatiana Costa (Aveiro Research Support Office), Nikolai Sobolev and Carlos Herdeiro (both RISE projects coordinator from the Aveiro Physics Department) was present in the RISE coordinator's day at the head of REA (Research Executive Agency) in Brussels, in 18-19 January 2018. The photo shows the RISE coordinators of the Math/Physics panel with REA staff, including Project Officer Amanda Jane Ozin-Hofsaess and the Head of Unit Fredrik Olsson Hector.

Ema Valente is now a Master

Ema Valente successfully finished her Physics M.Sc. at Aveiro University, on December 20th 2017, by defending a thesis with title "A simple model of exotic compact objects: interaction with a scalar field". This thesis was supervised by Gr@v researcher C. Herdeiro and examined by Prof. Luis Crispino, from the U. Federal do Pará, Brazil. Well done Ema!

New SPRG officers

The fourth general assembley of the Portuguese Relativity and Gravitation Society (SPRG) ellected the following new officers: C. Herdeiro (president), J. Natário (vice-president), V. Cardoso (Treasurer), J. Lemos (General Assembley President), F. Mena (First Secretary), J. Costa (Second secretary). These officers appear in the above photograph presenting the 2017 Alberto Prize to M. Zilhão. The remaining officer is J. Rocha ("Fiscal Único").
