Constraints on primordial magnetic fields from the optical depth of the cosmic microwave background
Kerstin E. Kunze, Eiichiro Komatsu
Damping of magnetic fields via ambipolar diffusion and decay of magnetohydrodynamical (MHD) turbulence in the post decoupling era heats the intergalactic medium (IGM). Delayed reco…
Revisiting the semiclassical gravity scenario for gravitational collapse
C. Barcelo, S. Liberati, S. Sonego +1
The existence of extremely dark and compact astronomical bodies is by now a well established observational fact. On the other hand, classical General Relativity predicts the existe…
Separating expansion from contraction and generalizing TOV condition in spherically symmetric models with pressure
Morgan Le Delliou, José Pedro Mimoso
We investigate spherically symmetric solutions with pressure and discuss the existence of a dividing shell separating expanding and collapsing regions. We perform a 3+1 splitting a…
High-resolution Smoothed Particle Hydrodynamics simulations of the merger of binary white dwarfs
P. Lorén-Aguilar, J. Isern, E. García-Berro
We present the results of a set of high-resolution simulations of the merging process of two white dwarfs. In order to do so, we use an up-to-date Smoothed Particle Hydrodynamics c…
The wave equation on axisymmetric stationary black hole backgrounds
Mihalis Dafermos
Understanding the behaviour of linear waves on black hole backgrounds is a central problem in general relativity, intimately connected with the nonlinear stability of the black hol…
Information geometry of asymptotically AdS black holes
Jan E. Aman, Narit Pidokrajt, John Ward
We investigate thermodynamic geometries of two families of asymptotically Anti-de Sitter black holes, i.e. the Reissner-Nordström Anti-de Sitter in four dimensions and the BTZ blac…
On the boundary of the region containing trapped surfaces
José M. M. Senovilla
The boundary of the region in spacetime containing future-trapped closed surfaces is considered. In asymptotically flat spacetimes, this boundary does not need to be the event hori…
Non-abelian black holes and black strings in higher dimensions
Betti Hartmann
We review the properties of static, higher dimensional black hole solutions in theories where non-abelian gauge fields are minimally coupled to gravity. It is shown that black hole…
Inhomogeneous String Cosmologies
John D. Barrow, Kerstin E. Kunze
We present exact inhomogeneous and anisotropic cosmological solutions of low-energy string theory containing dilaton and axion fields. The spacetime metric possesses cylindrical sy…
