Abstract: We investigate the thermodynamics of spherically symmetric black hole solutions in a four-dimensional Einstein--Yang-Mills-SU(2) theory with a negative cosmological constant. Special attention is paid to configurations with a unit magnetic charge.
Gr@v researchers have found that there are only two equilibrium possibilities for the spin of black hole binaries, and that they are similar to the equilibria observed for the spin of the Moon, which was identified by Giovanni Domenico Cassini in 1693. The results were published this week in MNRAS Letters.
This year's Chilean school on gravitation took place in Concepción, from 4-8 January, focused on black holes and solitons. One of the invited lecturers was Gr@v member C. Herdeiro, delivering a five lectures course on "Asymptotically flat black holes with scalar hair in four spacetime dimensions."
Abstract: Spontaneous scalarization is a scenario in some scalar-tensor theories of gravity where non-perturbative (order-of-unity strength) scalar fields can develop near neutron stars.
Exactly one hundred years after Einstein's completion of the general theory of relativity, Gr@v gathered some collaborators and friends to celebrate Gr@vity!
Pedro Cunha did his undergraduate in Physics and M.Sc in Astrophysics, both at the University of Coimbra. His M.Sc. thesis was already done within Gr@v under the supervision of C. Herdeiro. Pedro is pursuing his Ph.D. studies at the University of Aveiro and IST-Lisbon.
Abstract: I will give an overview of the program to use AdS/CFT techniques to explore the classical and quantum dynamics near cosmological singularities.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
