An analytic model of long string network evolution, recently developed by the authors, is presented in detail, and modified to describe string loop evolution. By treating the average string velocity, as well as the characteristic lengthscale, as dynamical variables, one can include the effects of frictional forces on the evolution of the network. This generalized `one-scale' model provides a quantitative picture of the complete evolution of a string network, including the prediction of previously unknown transient scaling regimes and a detailed analysis of the evolution of the loop population. The evolution of all cosmologically interesting string networks is studied in detail, and possible consequences of our results are discussed.

  1. LISA Reconstruction Landscape for Metastable Cosmic Strings

    hep-ph 2026-07 conditional novelty 6.0 of 10

    LISA can reconstruct metastable cosmic-string tension and lifetime when it samples the tail-to-plateau transition, with residual κ_CS sensitivity possible even in high-SNR plateau-like spectra.

  2. Gravitational waves from cosmic strings with friction: analytical approximations and parameter space

    astro-ph.CO 2026-05 unverdicted novelty 5.0 of 10

    Analytical approximations for the ultra-high-frequency GW peak sourced by friction-era cosmic string loops, with expanded observable parameter space.

  3. High-Quality Axion Dark Matter at Gravitational Wave Interferometers

    hep-ph 2025-09 unverdicted novelty 5.0 of 10

    In gauged U(1) completions enabling high-quality axion dark matter, cosmic string loops generate a stochastic gravitational wave background with an infrared break frequency that exceeds foregrounds above 10^14 GeV bre...

  4. Cosmic string gravitational wave backgrounds at LISA: I. Signal survey, template reconstruction, and model comparison

    astro-ph.CO 2025-08 unverdicted novelty 5.0 of 10

    As provided, the manuscript body (random lasing) does not correspond to the abstract (cosmic string gravitational wave backgrounds at LISA), leaving the abstract's quantitative claims unsupported by any accessible text.

  5. Not-quite-primordial black holes seeded by cosmic string loops

    astro-ph.CO 2025-07 conditional novelty 5.0 of 10

    Cosmic string loops moving through the early universe can seed halos that collapse into 10^5 solar mass black holes, potentially explaining JWST's little red dots.

  6. Scaling solutions for current-carrying cosmic string networks. II. Biased solutions

    hep-ph 2025-06 conditional novelty 5.0 of 10

    By relaxing the unbiased-loss assumption in the CVOS model, the paper finds new asymptotic scaling solutions for current-carrying cosmic strings, some of which have no unbiased analog.

  7. Constraints on Cosmic Strings from the Curl-Mode CMB Lensing Power Spectrum measured by ACT DR6

    astro-ph.CO 2026-06 unverdicted novelty 4.0 of 10

    ACT DR6 curl lensing yields 2σ bounds Gμ P^{-1} ≤ 3.5×10^{-5} (small-P) and Gμ ≤ 5.0×10^{-5} (P=1), tightened further with Planck 2013 data.

  8. Magnetic monopoles and high frequency gravitational waves from quasi-stable strings

    hep-ph 2026-03 conditional novelty 4.0 of 10

    SO(10) breaking through flipped SU(5) or Pati-Salam subgroups can produce GUT monopoles from merging monopole-antimonopole pairs, while the intervening quasi-stable strings emit gravitational waves from Hz to kHz.

  9. Cosmic Strings as Dynamical Dark Energy: Novel Constraints

    astro-ph.CO 2025-05 conditional novelty 4.0 of 10

    Cosmic string networks are constrained to less than ~1% of the energy density using CMB+BAO+SN data, with some models preferring mildly negative densities but no Bayesian evidence favoring them over LambdaCDM.

  10. C-parity, magnetic monopoles and higher frequency gravitational waves

    hep-ph 2025-02 conditional novelty 4.0 of 10

    The C-string-wall network from SO(10) breaking with unbroken C-parity produces a gravitational wave background peaking between 100 Hz and 100 kHz for intermediate breaking scales around 10^10 to 10^12 GeV.

  11. Indirect dark matter searches with neutrino telescopes via energetic cosmic showers

    hep-ph 2025-09 reject novelty 3.0 of 10

    Bounds on Z'-mediated dark matter are derived from neutrino telescopes, freeze-in, and cosmic strings, but the telescope bounds rest on comparing a Galactic-center flux to faraway sources.

  12. Waveform Modelling for the Laser Interferometer Space Antenna

    gr-qc 2023-11 unverdicted novelty 2.0 of 10

    A review of existing waveform models for LISA sources and the challenges that must still be overcome.
