Can our Universe be inhomogeneous on large sub-horizon scales ?
P. P. Avelino, J. P. M. de Carvalho, C. J. A. P. Martins +1
We show that our Universe may be inhomogeneous on large sub-horizon scales without us being able to realise it. We assume that a network of domain walls permeates the universe divi…
Extending the Velocity-dependent One-scale String Evolution Model
C. J. A. P. Martins, E. P. S. Shellard
We provide a general overview of the velocity-dependent one-scale model for cosmic string evolution and discuss two further extensions to it. We introduce and justify a new ansatz…
Topological defects: fossils of an anisotropic era?
P. P. Avelino, C. J. A. P. Martins
We consider the evolution of domain walls produced during an anisotropic phase in the very early universe, showing that the resulting network can be very anisotropic. If the domain…
