abstract

The $\Lambda$CDM cosmology passes demanding tests that establish it as a good approximation to reality. The theory is incomplete, of course, and open issues are being examined in active research programs. I offer a review of less widely discussed anomalies that might also point to hints to a still better cosmological theory if more closely examined.

Discussion (0). Continue with ORCID to comment.

  1. Probing Gravity -- Fundamental Aspects of Metric Theories and their Implications for Tests of General Relativity

    gr-qc 2024-12 unverdicted novelty 7.0 of 10

    Gravitational wave memory is shown to arise naturally from the Isaacson backreaction formalism in general metric theories of gravity, unifying null and ordinary memory and providing a memory formula valid beyond GR.

  2. Probing the fate of large primordial perturbations with exoplanets

    astro-ph.CO 2026-06 conditional novelty 6.5 of 10

    Observed ultra-wide exoplanets already constrain the amplitude and scale of primordial power-spectrum peaks that produce ultra-compact minihalos, with misalignment signatures as a future probe.

  3. Observational constraints on vector-like dark energy

    astro-ph.CO 2025-02 conditional novelty 6.0 of 10

    Pantheon and H(z) data force the cosmic triad vector dark energy model to sit very close to the LambdaCDM limit.

  4. Redshift tomography of the kinematic matter dipole

    astro-ph.CO 2024-12 conditional novelty 6.0 of 10

    Redshift bin edges create a Doppler-boost boundary term in the kinematic matter dipole that can match or reverse the standard Ellis-Baldwin signal.

  5. Comparison of $R_h=ct$ and $\Lambda$CDM using DESI DR1 measurements

    astro-ph.CO 2025-06 conditional novelty 5.0 of 10

    Using DESI DR1 distance measurements, flat LambdaCDM is decisively preferred over R_h=ct, driven almost entirely by the Lyman-alpha data point at redshift 2.33.

  6. Little ado about everything II: an `emergent' dark energy from structure formation to rule cosmic tensions

    astro-ph.CO 2025-02 conditional novelty 5.0 of 10

    An ensemble-averaged stochastic cosmology with a 'little ado' noise term produces an emergent dark energy that fits late-time data and claims to relieve the H0 and f sigma8 tensions.

  7. Evolution of matter perturbations in the context of cosmic slowing down

    gr-qc 2026-08 conditional novelty 4.0 of 10

    For five phantom-capable dark-energy parameterizations, the growth index at redshift zero is about 0.54 with a negative slope, and the f-sigma-8 combination lies below the Lambda-CDM prediction over most of the redshi...

  8. Effect of Peak Absolute Magnitude of Type Ia Supernovae and Sound Horizon Values on Hubble Tension using DESI results

    astro-ph.CO 2024-12 conditional novelty 4.0 of 10

    Using DESI DR1, Pantheon+ and cosmic chronometer data, the authors show that changing the Type Ia supernova absolute magnitude and sound-horizon priors moves the inferred H0 from about 73 to 68 km/s/Mpc, reducing the ...
