The Probe of Inflation and Cosmic Origins (PICO) is a proposed probe-scale space mission consisting of an imaging polarimeter operating in frequency bands between 20 and 800 GHz. We describe the science achievable by PICO, which has sensitivity equivalent to more than 3300 Planck missions, the technical implementation, the schedule and cost.

  1. Cosmic Collider Gravitational Waves sourced by Right-handed Neutrino production from Bubbles: Testing Seesaw, Leptogenesis and Dark Matter

    astro-ph.CO 2026-01 unverdicted novelty 7.0 of 10

    Bubble collisions in a seesaw model produce right-handed neutrinos that source novel gravitational waves detectable by LISA, ET, and LVK while allowing the lightest RHN to explain dark matter or enable leptogenesis.

  2. Reconstructing inflationary features on large scales using genetic algorithm

    astro-ph.CO 2026-04 unverdicted novelty 5.0 of 10

    Genetic algorithm reconstructs single-field inflationary models with features in the scalar power spectrum that fit Planck 2018 CMB data better by Δχ² ≲ -10 and suggest alternative background parameters.

  3. Probing String-Theory-Inspired Topologies of the Early Universe through CMB Temperature and Polarization Anisotropies

    astro-ph.CO 2026-05 unverdicted novelty 4.0 of 10

    Reexamination of Planck CMB data finds a possible spatial-parity-breaking signal consistent with six extra dimensions compactified toroidally at the GUT scale before inflation.
