VI Amazonian Symposium on Physics
The VI Amazonian Symposium on Physics will take place in Belém, Brazil, from 18-22 November 2024, jointly organized and with a strong participation of our group and integrated in the NewFunFiCO network.
Strong Gravity News & Events
Seminar at UFPA
C. Herdeiro visited the U. Federal do Pará, Brazil, and presented a seminar on Oct 23rd about the recent paper "Black holes in scalar multipolar Universes". The beautiful blossomed tree is "Pau Brasil" that names the country, due to its ember-colour wood.
Testing General Relativity with Extreme Mass Ratio Inspirals
Speaker
Susanna Barsanti (University College Dublin)
Event date
Venue
On-site: Sala Sousa Pinto
Event type
Extreme Mass Ratio Inspirals (EMRIs) - asymmetric binary systems composed by a stellar mass compact object inspiralling into a massive black hole - are promising candidates for probing new fundamental physics.
European Researchers Night 2024
A team of Gr@v Ph.D. students led by José Ferreira, featuring also Manuel Mariano and Nuno Santos participated in the European Researchers Night at Fábrica, the Aveiro outreach science centre. Amongst the attractions, there was the lensing effect due to a black hole that caught the public's attention.
Best poster award
Sergio Xavier, who obtained his Ph.D. from U. Federal do Pará, Brazil, under the supervision of Prof. L. Crispino in August 2024, received a best poster award in the XLII Brazilian National Meeting on the Physics of Particles and Fields. The poster was on work in collaboration with our group.
Three Gr@v members in the world's top 2% scientists
Three Gr@v members appear in the 2024 updated science-wide author databases of standardized citation indicators, commonly known as the Stanford University ranking of top 2% scientists in the world. The top 100 scientists in Portugal, from the same raking, features one CIDMA and Gr@v researcher.
Darío's farewell
Group get together to cellebrate Prof. Darío Nuñez, from UNAM, Mexico City, one year visit (Oct 2023 - Sep 2024). Many thanks Darío for the wonderful discussions, positive energy and dynamics. We hope you come back soon!
No-go theorems for gravitating nonlinear electromagnetic fields
Speaker
Ana Bokulić (University of Zagreb)
Event date
Venue
On-site: Sala Sousa Pinto
Event type
Nonlinear electrodynamics (NLE) is an umbrella term for various nonlinear generalisations of Maxwell’s theory, usually defined by Lagrangians depending on two quadratic electromagnetic invariants. We discuss two classes of no-go theorems that can be established when NLE fields are coupled to gravity.
Dinner with many visitors
On Wednesday 18, we gathered for a dinner in town to celebrate our many visitors. While Víctor Jaramillo (University of Science and Technology of China), Raimon Luna and Milton Ruiz (both from University of Valencia) joined us for a week, we also welcomed longer term guests Ana Bokulić (University of Zagreb) and Razieh Ranjbar (Ferdowsi University).
