Monopole-antimonopole pairs connected by strings can be formed as topological defects in a sequence of cosmological phase transitions. Such hybrid defects typically decay early in the history of the universe but can still generate an observable background of gravitational waves. We study the spectrum of gravitational radiation from these objects both analytically and numerically, concentrating on the simplest case of an oscillating pair connected by a straight string.

  1. Do Cosmic String Segments Emit Gravitational Waves?

    hep-ph 2025-07 conditional novelty 7.0 of 10

    In realistic metastable cosmic string scenarios, thermal fluctuations on the string prevent endpoint monopoles from reaching relativistic speeds, so string segments contribute negligibly to the gravitational wave background.

  2. Searching Stochastic Gravitational Wave Background Landscape Across Frequency Bands

    gr-qc 2025-11 conditional novelty 5.0 of 10

    A hybrid cosmic string–domain wall model can fit the NANOGrav 15-year signal, and its high-frequency tail lies within LISA's projected reach, making the interpretation testable.

  3. 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.

  4. Monopoles, Strings, Walls and Gravitational waves

    hep-ph 2026-07 conditional novelty 4.0 of 10

    Breaking SU(2) flavor gauge symmetry stepwise to nothing leaves monopoles, strings, and walls; collapsing walls can form composite strings whose gravitational-wave spectra fit PTA data and lie within reach of LVK and ...
