Localisation of massive fermions on the brane
C. Ringeval, P. Peter, J. -P. Uzan
We construct an explicit model to describe fermions confined on a four dimensional brane embedded in a five dimensional anti-de Sitter spacetime. We extend previous works to accomm…
Fermionic current-carrying cosmic strings: zero-temperature limit and equation of state
P. Peter, C. Ringeval
The equation of state for a superconducting cosmic string whose current is due to fermionic zero modes is derived analytically in the case where the back-reaction of the fermions t…
Planck 2013 results. XXV. Searches for cosmic strings and other topological defects
Planck Collaboration, P. A. R. Ade, N. Aghanim +225
Planck data have been used to provide stringent new constraints on cosmic strings and other defects. We describe forecasts of the CMB power spectrum induced by cosmic strings, calc…
Planck 2013 results. XV. CMB power spectra and likelihood
Planck collaboration, P. A. R. Ade, N. Aghanim +257
We present the Planck likelihood, a complete statistical description of the two-point correlation function of the CMB temperature fluctuations. We use this likelihood to derive the…
Planck 2013 results. I. Overview of products and scientific results
Planck Collaboration, P. A. R. Ade, N. Aghanim +398
The ESA's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre sk…
Exploring Cosmic Origins with CORE: Survey requirements and mission design
J. Delabrouille, P. de Bernardis, F. R. Bouchet +200
Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this p…
Wavelet-Bayesian inference of cosmic strings embedded in the cosmic microwave background
J. D. McEwen, S. M. Feeney, H. V. Peiris +3
Cosmic strings are a well-motivated extension to the standard cosmological model and could induce a subdominant component in the anisotropies of the cosmic microwave background (CM…
Multi-Scale Pipeline for the Search of String-Induced CMB Anisotropies
A. Vafaei Sadr, S. M. S. Movahed, M. Farhang +2
We propose a multi-scale edge-detection algorithm to search for the Gott-Kaiser-Stebbins imprints of a cosmic string (CS) network on the Cosmic Microwave Background (CMB) anisotrop…
