P. Cunha and C. Herdeiro were invited speakers at the online workshop on numerical and analytical relativity (NAR-2024), organized by the Department of Applied Sciences, Indian Institute of Information Technology Allahabad (IIITA) during 20 - 22 March 2024. The video recorded lectures can be seen here.
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.
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.
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).
A call for a 7-month research grant in Strong Gravity for M.Sc. holders, within the research grantGravitational waves and black holes as ultralight dark matter particle detectors, CERN/FIS-PAR/0024/2021, is open from December 7th to 21st, 2023. See attached document for details or the Euraxess announcementhere.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
