Cosmological perturbations are considered in $f(T)$ and in scalar-torsion $f(\varphi)T$ teleparallel models of gravity. Full sets of linear perturbation equations are accurately derived and analysed at the relevant limits. Interesting features of generalisations to other teleparallel models, spatially curved backgrounds, and rotated tetrads are pointed out.

  1. Cosmological Perturbation in New General Relativity: Propagating mode from the violation of local Lorentz invariance

    gr-qc 2025-09 conditional novelty 7.0

    In New General Relativity on a flat expanding universe, the propagating spectrum is computed for all nine types, with Type 3 carrying five stable tensor, scalar, and vector modes.

  2. Gauge-invariant cosmological perturbations in Type 3 New General Relativity and background-hierarchy bounds

    gr-qc 2026-05 unverdicted novelty 6.0

    Derives background-hierarchy bounds on the two free parameters of Type 3 NGR to ensure linear cosmological perturbation theory remains viable around flat FLRW.

  3. Gauge-invariant cosmological perturbations in Type 3 New General Relativity and background-hierarchy bounds

    gr-qc 2026-05 unverdicted novelty 5.0

    Derives background-hierarchy bounds for scalar, transverse-vector and tensor modes in Type 3 NGR around flat FLRW, identifying viable parameter regions where linear perturbation theory remains consistent.

  4. Higgs-like inflation in scalar-torsion $f(T,\phi)$ gravity in light of ACT-SPT-DESI constraints

    gr-qc 2025-12 conditional novelty 5.0

    Higgs-like inflation in f(T,φ) torsion gravity can accommodate the ACT/DESI upward shift in the scalar spectral index while predicting a tensor-to-scalar ratio r≈0.01–0.04.

  5. Cosmological Viability of Exponential Infrared $f(T)$ Gravity

    astro-ph.CO 2026-06 unverdicted novelty 4.0

    Exponential IR f(T) gravity Model I alleviates Hubble tension but is disfavoured by combined Planck/ACT/SPT+DESI+Pantheon+ data; Model II is ruled out because background constraints force unphysical shifts in CMB parameters.

  6. Vector modes in Type 3 New GR

    gr-qc 2026-05 unverdicted novelty 2.0

    Substituting constraint equations into the Lagrangian leads to false claims of dynamical vector modes in Type 3 New GR; analysis of the linear equations of motion confirms they are not dynamical.

  7. Vector modes in Type 3 New GR

    gr-qc 2026-05 unverdicted novelty 2.0

    Vector modes in Type 3 New GR are non-dynamical; substituting constraints into the Lagrangian produces incorrect claims of dynamics.
