abstract

The past 50 years has seen cosmology go from a field known for the errors being in the exponents to precision science. The transformation, powered by ideas, technology, a paradigm shift and culture change, has revolutionized our understanding of the Universe, with the $\Lambda$CDM paradigm as its crowning achievement. I chronicle the journey of precision cosmology and finish with my thoughts about what lies ahead.

  1. Expected redshift drift for tilted observers

    astro-ph.CO 2026-05 unverdicted novelty 6.0 of 10

    Redshift drift for tilted observers consists of an FLRW background term plus directional corrections from peculiar expansion, projected shear, and acceleration along the line of sight.

  2. Towards a unified quantum field theory of dark energy and inflation: unstable de Sitter vacuum and running vacuum

    gr-qc 2026-01 conditional novelty 6.0 of 10

    The vacuum energy of quantum fields, computed exactly in de Sitter spacetime and then allowed to decay into radiation, can drive H^4-powered inflation and leave a slowly running dark energy δρ_vac ~ m_Pl^2 H^2, unifyi...

  3. Extending CSST Emulator to post-DESI era

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

    A tuned 'spectral equivalence' mapping lets the CSST emulator predict nonlinear matter power spectra at ~1% accuracy across the DESI DR2+CMB dynamic-dark-energy posterior.

  4. Testing Quasi-Linear Coasting Cosmologies with Late-Time Large-Scale Structure Growth

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

    A closed-form growth factor for linearly expanding (coasting) cosmologies is derived and fit to fσ8 data, showing all tested models are consistent but Lambda-CDM is statistically preferred.

  5. Modeling dark matter halos with self-interacting fermions: A polytropic approach

    hep-ph 2025-12 reject novelty 4.0 of 10

    A single ~40 eV self-interacting fermion is claimed to fit rotation curves of many galaxies with one adjustable density per galaxy, but fit quality and reported parameter ranges are inconsistent.

  6. Running Vacuum in the expanding Universe: a unified QFT paradigm for Inflation and Dark Energy

    gr-qc 2026-06 unverdicted novelty 3.0 of 10

    The running vacuum model derives dynamical vacuum energy from QFT in curved spacetime, using H^4 terms for inflation and H^2 terms for dark energy while G evolves logarithmically.
