Initial data for black hole collisions

S. Dain

I describe the construction of initial data for the Einstein vacuum equations that can represent a collision of two black holes. I stress in the main physical ideas.

Stationary structure of relativistic superfluid neutron stars

R. Prix, J. Novak, G. L. Comer

We describe recent progress in the numerical study of the structure of rapidly rotating superfluid neutron star models in full general relativity. The superfluid neutron star is de…

A new class of obstructions to the smoothness of null infinity

J. A. Valiente-Kroon

Expansions of the gravitational field arising from the development of asymptotically Euclidean, time symmetric, conformally flat initial data are calculated in a neighbourhood of s…

Perturbative Solutions of the Extended Constraint Equations in General Relativity

Adrian Butscher

The extended constraint equations arise as a special case of the conformal constraint equations that are satisfied by an initial data hypersurface in an asymptotically simple s…

On the existence of global solutions for -Gowdy spacetimes with stringy matter

Makoto Narita

We show a global existence theorem for Einstein-matter equations of -Gowdy symmetric spacetimes with stringy matter. The areal time coordinate is used. It is shown that this…

Doing numerical cosmology with the Cactus code

D. N. Vulcanov

The article presents some aspects concerning the construction of a new thorn for the Cactus code, a complete 3-dimensional machinery for numerical relativity. This thorn is complet…
