Projects
Ongoing research programmes, described by the question each one tries to answer.
Expansion and dark energy · Active
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.
Expansion and dark energy · Active
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 · Active
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 · Active
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 · Active
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 · Active
Gravitational dynamics of the Local Group
Models the Milky Way–M31 orbit and the Local Group mass from astrometric and dynamical data.
Catalogue anomalies · Active
Anomaly detection in catalogues
Scans public catalogues for statistical departures and checks the novelty of each candidate before any further calculation.
Reproducibility · Active
Reproducibility and agent-assisted research
Keeps calculations re-runnable, with data, versions and criteria recorded, and uses computational agents under explicit verification rules.
