We revise the expansion history of the scalar field theories known as Kinetic Gravity Braiding. These theories are well-known for the possibility of driving the expansion of the cosmos towards a future self-tuning de Sitter state when the corresponding Lagrangian is invariant under constant shifts in the scalar field. Nevertheless, this is not the only possible future fate of these shift-symmetric models. Using a dynamical system formulation we show that future cosmological singularities can also appear in this framework. Moreover, we present explicit examples where the future attractor in the configuration space of the theory corresponds to a big rip singularity.

  1. Alleviating the Hubble Tension with Smooth Sign-Switching Dark Energy: Full CMB Constraints with DESI and PantheonPlus

    astro-ph.CO 2026-07 conditional novelty 6.0 of 10

    Smooth ECDM dark energy remains compatible with Planck+ACT+SPT, DESI DR2 and Pantheon+/SH0ES while alleviating the Hubble tension through a controlled late-time density transition.

  2. Observational constraints on 3-forms dark energy

    astro-ph.CO 2025-12 conditional novelty 6.0 of 10

    Fitting a Gaussian-potential 3-form dark-energy model to Planck, DESI, Pantheon+, Cepheid and DES data shifts H0 up by only ~0.4 km/s/Mpc and yields a weak statistical preference over ΛCDM.

  3. Cosmographic analysis of sign-switching dark energy

    gr-qc 2025-06 conditional novelty 5.0 of 10

    New sign-switching dark energy models with ladder, smooth-step and error-function profiles are introduced and compared, with continuous transitions shown to convert the Lambda_sCDM sudden singularity into a milder w-s...
