ICGC 24 and ICRAC 24
C. Herdeiro was one of the plenary invited speakers of the International Conference on Gravitation and Cosmology (ICGC 24) and the International Conference on Relativistic Astrophysics and Cosmology (ICRAC 24) that took place in Lahore, Pakistan on 29-31 Jan and 1-2 Feb 2024. Wonderful hospitality and great interactions. Science brings people together.
Numerical evolution of well-posed field theories with anisotropic scaling
Speaker
Marcelo Rubio (SISSA, Trieste)
Event date
Venue
On-site: Room TBD
Event type
Dynamical equations exhibiting an anisotropic scaling between space
and time admit a dispersive nature, as they contain higher-order spatial derivatives,
but remain second order in time.
Phys.org coverage
Read here the phys.org coverage of two papers published in Phys. Rev. X and Phys. Rev. D in December 2023, involving members of Gr@v.
Young brown dwarfs and rogue planets in the Milky Way
Speaker
Koraljka Muzic (IA, University of Lisbon)
Event date
Venue
Hybrid: Sala Sousa Pinto and Zoom
Event type
There are at least 100 billion brown dwarfs and planetary-mass objects in our Galaxy - objects that are not orbiting a star and have masses between that of Jupiter and of the lowest mass stars (~80 MJup). Several theories for their formation have been proposed, and could all as well be at work, but their relative importance is not known and is expected to vary with mass and environment.
SpheriCo.jl: Spherical Collapse in Julia

Black hole formation is a physical process extensively
XVI Black Holes Workshop in Porto
15 years after the first edition of the Black Holes Workshop that took place at the Faculty of Sciences of Porto University, the XVI Black Holes Workshop returned to Porto, this time in the Faculty of Engineering. The next edition will take place at the University of Aveiro on 19-20 December 2024.
Gr@v paper in Physical Review X
An article on the parameter inference from gravitational wave signals using a novel methodology based on the Newman-Penrose scalar was published this month (December 2023) in Physical Review X. The article is co-authored by Gr@v members C. Herdeiro and E. Radu. PRX has similar quality standards as Physical Review Letters but for longer papers. It has an impact factor of 12.5 (2022).
