Research
Find expansion tests, comparisons across probes and searches in galaxy catalogues. Each research area links to its records.

Expansion and dark energy
Dark energy, the expansion history and the H₀ tension.
Dark energy and the expansion history
Tests whether the expansion of the Universe requires dark energy that evolves in time, comparing ΛCDM and its extensions against BAO, supernovae, cosmic chronometers and the CMB under the same data and priors.
The H₀ tension
Examines how distance-ladder calibrations and early- or late-time expansion models change the inferred value of H₀, and which observables separate those explanations.
Models and perturbations
Alternative cosmological models and the evolution of their perturbations.
Alternative cosmological models and perturbations
Builds and confronts effective models with perturbation evolution, so that the same theory is tested on both background and structure.
CMB, BAO and growth
The CMB, BAO, supernovae, structure growth and gravitational waves.
Structure growth, the CMB and gravitational waves
Uses independent probes to check whether a preference seen in one data set survives other observables.
Galaxies and exotic objects
JWST, LRDs and compact high-redshift sources.
High-redshift galaxies, LRDs and exotic objects
Selects and characterises compact JWST sources with explicit criteria, separating rediscoveries from candidates with no counterpart in the literature.
Local Group
Gravitational dynamics of the Milky Way, M31 and the Local Group.
Gravitational dynamics of the Local Group
Models the Milky Way–M31 orbit and the Local Group mass from astrometric and dynamical data.
Catalogue anomalies
Anomaly detection and analysis of astronomical catalogues.
Anomaly detection in catalogues
Scans public catalogues for statistical departures and checks the novelty of each candidate before any further calculation.
Reproducibility
Re-runnable methods and agent-assisted research.
Reproducibility and agent-assisted research
Keeps calculations re-runnable, with data, versions and criteria recorded, and uses computational agents under explicit verification rules.
