abstract

We study diffusion damping of acoustic waves in the photon-baryon fluid due to cosmic strings, and calculate the induced $\mu$- and $y$-type spectral distortions of the cosmic microwave background. For cosmic strings with tension within current bounds, their contribution to the spectral distortions is subdominant compared to the distortions from primordial density perturbations.

  1. 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.
