We provide an update on the work of di Serego Alighieri (2015), focusing on recent developments regarding constraints on Cosmic Polarization Rotation (CPR), also known as Cosmic Birefringence (CB), derived from Cosmic Microwave Background (CMB) polarization data.

  1. Planck constraints on the scale dependence of isotropic cosmic birefringence

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

    Planck polarization data favor a constant cosmic birefringence angle (β≈0.3°) across multipoles, with scale dependence consistent with zero at up to 1.8σ.

  2. Twisted echoes of an odd quartet: Scalar-induced gravitational waves as a probe of primordial parity-violation

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

    A parity-odd primordial trispectrum imprints measurable left-right asymmetry in scalar-induced gravitational waves, and the chirality ratio directly tracks the parity-odd to parity-even trispectrum amplitude ratio.

  3. Constraining primordial non-Gaussianity and parity-violation through Scalar-Induced Gravitational Waves with next-generation ground-based interferometers

    astro-ph.CO 2026-07 conditional novelty 5.0 of 10

    ET+CE forecast: injected SIGW parameters (A_p, f_peak, f_NL, tau_NL, parity-odd tau_tilde_NL) are recovered within 1-2 sigma despite an astrophysical foreground, but the chiral V-mode is sub-threshold (SNR 0.5-1.9).
