Emission of gravitational waves by superconducting cosmic strings
I. Yu. Rybak, L. Sousa
We study the gravitational radiation emission efficiency of superconducting cosmic strings. We demonstrate, by using a solvable model of transonic strings, that the presence of…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Analytical scaling solutions for the evolution of cosmic domain walls in a parameter-free velocity-dependent one-scale model
P. P. Avelino, D. Grüber, L. Sousa
We derive an analytical approximation for the linear scaling evolution of the characteristic length and the root-mean-squared velocity of standard frictionless domain wal…
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…
Domain walls and other defects in Eddington-inspired Born-Infeld gravity
P. P. Avelino, L. Sousa
We investigate domain wall and other defect solutions in the weak-field limit of Eddington-inspired Born-Infeld gravity as a function of , the only additional parameter of the t…
Probing the gravitational wave background from cosmic strings with LISA
Pierre Auclair, Jose J. Blanco-Pillado, Daniel G. Figueroa +8
Cosmic string networks offer one of the best prospects for detection of cosmological gravitational waves (GWs). The combined incoherent GW emission of a large number of string loop…
