On May 29th, 1919 a joint Royal Astronomical Society and Royal Society expedition led by Arthur Eddington to Principe observed a total solar eclipse, confirming the deflexion of light predicted by the General Theory of Relativity. Eddington at Sundy: 100 years later (E@S) results from a joint initiative of several institutions, including our group, to celebrate the centenary of these observations.
Gr@v members C. Herdeiro and E. Radu visited the University of Mons (Belgium) in March 2018, to continue their scientific collaboration with Professor Yves Brihaye. Herdeiro presented a seminar on the group's work. And, as demanded by tradition, they all paid a visit to the Guardhouse monkey of Mons!
The invited review article "Shadows and strong gravitational lensing: a brief review", by Gr@v members P. Cunha and C. Herdeiro was selected as Editor's choice in General Relativity and Gravitation.
The black hole theorist and cosmologist Stephen Hawking passed away at the age of 76. Stephen Hawking distinguished himself not only as a brilliant scientist, with remarkable contributions such as the discovery of black hole evaporation, but also as an active science communicator with best selling books, most notably A brief history of time.
"SKA days PT" took place last 6 and 7 of February, at Covilhã and Lisbon, an initiative to promote the Square Kilometer Array (SKA) - the world's largest radio telescope - among the Portuguese scientific and business communities.
SKA project has the participation of 19 countries, in the case of Portugal it is via the infrastructure ENGAGE SKA, which is a consortium composed by the Instituto de Telecomunicações, the Universities of Aveiro (Gr@v), Porto and Évora, and the Polytechnic Institute of Beja.
Greybody factors are frequency dependent quantities that measure the deviation from the perfect black body spectrum of Hawking radiation, and they provide us with valuable information about the near horizon structure of black holes. In
addition, when black holes are perturbed the geometry of spacetime undergoes dumbed oscillations.
DOPPLER (DevelOpment of PaloP knowLEdge in Radioastronomy), coordinated by Dr. Valério Ribeiro of Gr@v (University of Aveiro), is a recently funded FCT and the Aga Khan Development Network project.
The first global meeting of the COST Action ”CA 16104 Gravitational waves, black holes and fundamental physics (GWverse)” took place in Malta, Gravity@Malta2018 (22-25 January 2018). The meeting brought together three normally disjoint communities, namely Gravitational Wave detection and analysis, BH modeling (in both astrophysical and GR contexts), and strong-gravity tests of fundamental physics.
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.
