CMB anisotropies generated by cosmic string loops
I. Yu. Rybak, L. Sousa
We investigate the contribution of cosmic string loops to the Cosmic Microwave Background (CMB) anisotropies. This is done by extending the Unconnected Segment Model (USM) to inclu…
Generalised velocity-dependent one-scale model for current-carrying strings
C. J. A. P. Martins, Patrick Peter, I. Yu. Rybak +1
We develop an analytic model to quantitatively describe the evolution of superconducting cosmic string networks. Specifically, we extend the velocity-dependent one-scale (VOS) mode…
Revisit of Y-junctions for strings with currents: transonic elastic case
I. Yu. Rybak
We studied the formation of Y-junctions for transonic elastic strings. In particular, using the gen-eral solution for these strings, which is described by left- and right-moving mo…
Dynamics of junctions and the multi-tension velocity-dependent one-scale model
I. Yu. Rybak, A. Avgoustidis, C. J. A. P. Martins
The dynamics of string junctions and their influence on the evolution of cosmic superstring networks are studied in full detail. We review kinematic constraints for colliding strin…
Collisions of cosmic strings with chiral currents
I. Yu. Rybak, A. Avgoustidis, C. J. A. P. Martins
We present an analytic study of cosmic superconducting chiral string collisions in Minkowski space, applying the kinematic constraints that arise from the relevant generalization o…
Extending the velocity-dependent one-scale model for domain walls
C. J. A. P. Martins, I. Yu. Rybak, A. Avgoustidis +1
We report on an extensive study of the evolution of domain wall networks in Friedmann-Lema\^ıtre-Robertson-Walker universes by means of the largest currently available field-theory…
