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
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
New CMB constraints for Abelian Higgs cosmic strings
We present cosmic microwave background (CMB) power spectra from recent numerical simulations of cosmic strings in the Abelian Higgs model and compare them to CMB power spectra measured by Planck. We
Cosmic Microwave Background constraints for global strings and global monopoles
We present the first CMB power spectra from numerical simulations of the global O(N) linear $\sigma$-model with N = 2,3, which have global strings and monopoles as topological defects. In order to
Energy-momentum correlations for Abelian Higgs cosmic strings
We report on the energy-momentum correlators obtained with recent numerical simulations of the Abelian Higgs model, essential for the computation of cosmic microwave background and matter
Irreducible background of gravitational waves from a cosmic defect network: Update and comparison of numerical techniques
Cosmological phase transitions in the early Universe may produce relics in the form of a network of cosmic defects. Independently of the order of a phase transition, topology of the defects, and
Scaling Density of Axion Strings.
TLDR
The residuals from the constant-ζ (linear ξ) fit show no evidence for logarithmic growth, restoring confidence that numerical simulations can be simply extrapolated from the Peccei-Quinn symmetry-breaking scale to the QCD scale.

Type I Abelian Higgs strings: Evolution and cosmic microwave background constraints
We present results from the first simulations of networks of Type I Abelian Higgs cosmic strings to include both matter and radiation eras and Cosmic Microwave Background (CMB) constraints. In Type I
