Motivated by recent works of Sen and Gibbons, we study the evolution of a flat and homogeneous universe dominated by tachyon matter. In particular, we analyse the necessary conditions for inflation in the early roll of a single tachyon field.

  1. Gravitational memory effects in Tachyon gravity

    gr-qc 2025-07 conditional novelty 5.0 of 10

    In tachyon gravity, the scalar field adds a breathing memory mode to gravitational waves and modifies the Bondi mass loss and soft theorems.

  2. Constraining Quintessential Inflation with ACT: A Gauss-Bonnet Gateway

    astro-ph.CO 2026-04 unverdicted novelty 4.5 of 10

    Exponential and sech Gauss–Bonnet couplings restore ACT-compatible ns and r for quintessential inflation, while tanh fails for a structural sign reason; reheating remains BBN-safe.

  3. Analytical calculation of the observational parameters for tachyon inflation

    gr-qc 2026-05 unverdicted novelty 4.0 of 10

    Authors introduce new Hubble rate test functions for tachyon inflation, derive analytical ns and r using assumed slow-roll parameter dependence, and compare predictions to Planck data.

  4. Power Law Plateau Inflation and Primary Gravitational Waves in the light of ACT

    astro-ph.CO 2025-07 conditional novelty 4.0 of 10

    Power-law plateau inflation can sit inside the 1 sigma region of ACT DR6, but the reheating bound from gravitational waves forces the total number of e-folds N_k below about 62.
