In the first part of my talk, I give on overview of some recent results concerning the two-body problem in general relativity at high post-Newtonian (PN) order. I will present the energy flux at 4.5PN order, the equations of motion at 4.5PN order, and the memory contributions to the 3.5PN order waveform.

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.
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.
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.
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 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.
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!
