Fitting CMB data with cosmic strings and inflation
We perform a multiparameter likelihood analysis to compare measurements of the cosmic microwave background (CMB) power spectra with predictions from models involving cosmic strings. Adding strings to
CMB power spectrum contribution from cosmic strings using field-evolution simulations of the Abelian Higgs model
We present the first field-theoretic calculations of the contribution made by cosmic strings to the temperature power spectrum of the cosmic microwave background (CMB). Unlike previous work, in which
Exploring cosmic origins with CORE: Survey requirements and mission design
TLDR
The requirements for a future CMB polarisation survey addressing these scientific objectives are listed, and the design drivers of the COREmfive space mission proposed to ESA in answer to the "M5" call for a medium-sized mission are discussed.
Exploring cosmic origins with CORE: Inflation
We forecast the scientific capabilities to improve our understanding of cosmic inflation of CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a medium-size mission
CMB polarization power spectra contributions from a network of cosmic strings
We present the first calculation of the possible (local) cosmic string contribution to the cosmic microwave background polarization spectra from simulations of a string network (rather than a
CMB power spectra from cosmic strings: Predictions for the Planck satellite and beyond
We present a significant improvement over our previous calculations of the cosmic string contribution to cosmic microwave background (CMB) power spectra, with particular focus on sub-WMAP angular
Fitting cosmic microwave background data with cosmic strings and inflation.
TLDR
A multiparameter likelihood analysis is performed to compare measurements of the cosmic microwave background (CMB) power spectra with predictions from models involving cosmic strings, finding a 2sigma detection of strings in the standard case of a primordial spectrum with power-law tilt ns.
Evolution of cosmic superstring networks: A Numerical simulation
We study the formation and evolution of an interconnected string network in large-scale field-theory numerical simulations, both in flat spacetime and in expanding universe. The network consists of
Cosmic microwave anisotropies from BPS semilocal strings
We present the first ever calculation of cosmic microwave background (CMB) anisotropy power spectra from semilocal cosmic strings, obtained via simulations of a classical field theory. Semilocal
Scaling from gauge and scalar radiation in Abelian Higgs string networks
We investigate cosmic string networks in the Abelian Higgs model using data from a campaign of large-scale numerical simulations on lattices of up to $4096^3$ grid points. We observe scaling or
