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…
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…
Signature of inflation in the stochastic gravitational wave background generated by cosmic string networks
G. S. F. Guedes, P. P. Avelino, L. Sousa
A cosmic string network created during an inflationary stage in the early Universe - here defined as i-string network - is expected to enter a transient stretching regime during in…
Unveiling the Dynamics of the Universe
Pedro Avelino, Tiago Barreiro, C. Sofia Carvalho +10
We explore the dynamics and evolution of the Universe at early and late times, focusing on both dark energy and extended gravity models and their astrophysical and cosmological con…
