Within the decade long collaboration between Gr@v and the gravity group at Federal University of Pará, Brasil, C. Herdeiro visited the UFPA Campi in Belém and Salinas in August 2024, giving scientific seminars and outreach talks.
A computing proposal prepared by S. Gimeno-Soler, P. Cunha, I. Sengo and C. Herdeiro, and led by H. Olivares was awarded with 12 million CPU-hours at the supercomputer Mare Nostrum 5.
The project, titled "Exploring accretion and spacetime models for event-horizon-scale observations of low-luminosity active galactic nuclei", will explore new models of accretion flows and spacetime geometries for the targets of the Event Horizon Telescope using simulations as the one shown in the picture (Image credit: H. Olivares and P. Cunha).
C. Herdeiro visited the ICTP-Asia Pacific and the University of the Chinese Academy of sciences, in Beijing, presenting an invited seminar hosted by Prof. Yu Tian.
GW170817 and GRB 170817A provided direct evidence that binary neutron star (NSNS) mergers can produce short gamma-ray bursts (sGRBs). However, questions remain about the nature of the central engine.
The significance of multi-ring images in the optical appearance of spherically symmetric compact objects is discussed. Such images are produced by an optically and geometrically thin accretion disk illuminating the object.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
