Cosmology

Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.

For our latest developments/activities in this area, please see the listing below.

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.

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").

Scientists discuss black holes in Aveiro

The X Black Holes workshop took place at Aveiro University on 18-19 December 2017. It gathered almost 100 scientists discussing black holes from many different perspectives. Besides 63 oral communications, the workshop also included the fourth General Assembley of the Portuguese Relativity and Gravitation Society (SPRG) and a special session celebrating the 60th anniversary of Prof. J. S. Lemos.
