We investigate a new scenario of dark matter production in a bouncing universe, in which dark matter was produced completely out of equilibrium in the contracting as well as expanding phase. We explore possibilities of using dark matter as a probe of the bouncing universe, focusing on the relationship between a critical temperature of the bouncing universe and the present relic abundance of dark matter.

  1. Analytic Gravitational Wave Spectrum in Next-to-Minimal Bouncing Cosmology

    astro-ph.CO 2025-07 conditional novelty 6.0 of 10

    A five-phase bouncing cosmology yields a broken power-law gravitational wave spectrum whose amplitude bound automatically keeps the bounce energy below the Planck scale.

  2. Forecast Constraints on Bouncing Cosmology from High Frequency Gravitational Waves Using Superconducting LC Circuits and Resonant Cavities

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

    The paper forecasts that resonant-cavity and superconducting-circuit gravitational wave detectors could constrain the bounce energy scale of a generic bouncing cosmology far more tightly than astrophysical observatori...
