We present a fitting formula for the non-linear evolution of the bispectrum in CDM models, obtained from measurements in high resolution numerical simulations. The formula interpolates between the perturbative and highly non-linear regimes, and generalizes previous results obtained for scale-free initial conditions.

  1. Wedge-avoidance Fisher Forecasts for Primordial Non-Gaussianity from Dark-Ages 21-cm Power Spectrum and Bispectrum

    astro-ph.CO 2026-06 unverdicted novelty 6.0 of 10

    A wedge-aware Fisher framework is introduced to forecast PNG constraints from Dark Ages 21-cm power spectrum and bispectrum, demonstrating significantly weaker bounds due to mode loss in two oscillatory inflation models.

  2. Cosmic shear nulling as a geometrical cosmological probe: Methodology and sensitivity to cosmological parameters and systematics

    astro-ph.CO 2025-02 conditional novelty 6.0 of 10

    A null test of BNT-transformed cosmic shear cross-spectra can constrain Omega_m and w0 geometrically, but requires photometric redshifts known to about 10^-3 and is subdominant to standard 3x2pt analysis.
