We analyze the dynamics of a collisionless kinetic gas propagating in the exterior of a rotating Kerr black hole. We focus on the phase space region corresponding to orbits that are bounded in space.
The stimulating "Black Holes Inside and Out" meeting took place in Copenhagen, Denmark, in August 2024. C. Herdeiro was one of the invited speakers. More info here.
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).
This week Gr@v hosted A. Bernal and J. Barranco from Guanajuato (Mexico) and E. Gasperín from IST-Lisbon. Great seminars and discussions. Thank you for your visits!
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.
The "New horizons for Psi school and workshop" took place at IST Lisbon, from 1-5 July 2024. Gr@v members E. Radu and P. Cunha, as well as former member and external collaborator N. Sanchis-Gual, were invited speakers at the meeting.
C. Herdeiro was one of the invited lecturers of the school in Physics organized by Prof. Hongbao Zhang and the Beijing Normal University, in the Zhuhai campus, southern China.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
