We derive cosmological constraints on the annihilation cross section of dark matter with velocity-dependent structure, motivated by annihilating dark matter models through Sommerfeld or Breit-Wigner enhancement mechanisms. In models with annihilation cross section increasing with decreasing dark matter velocity, big-bang nucleosynthesis and cosmic microwave background give stringent constraints.

  1. Search for Dark Matter Annihilation and Decay with H$\alpha$ Line Emission

    hep-ph 2025-12 conditional novelty 7.0

    H-alpha line emission from recombining gas in quiet dwarf galaxies is a new probe of dark matter annihilation/decay, giving leading limits for some dark matter masses.

  2. The Glow of Axion Quark Nugget Dark Matter: (IV) CMB Spectral and Anisotropy Signatures

    astro-ph.CO 2025-12 conditional novelty 5.0

    Axion quark nugget dark matter would create a μ-type CMB spectral distortion near 6×10⁻⁸ with y near 2×10⁻⁹, detectable by proposed missions, while leaving CMB anisotropies essentially unchanged.
