In this repo you will find the python code to fit the cosmological model against various data sets including SN, CMB, CC, BAO.

Cosmology Group repo for its public webpage, reviews & publications on tensions in ΛCDM, redshift and the CMB

MDP-Ls (Matter Density Perturbations for Ls) is a software tool designed to compute both linear and non-linear matter density perturbations within the LsCDM cosmological model.

A geometric cosmological model where gravity is treated as a fourth spatial dimension. Accounts for horizons, redshift, galaxy rotation curves, time dilation, observability, and black hole behavior via geometric depth—without dark matter, dark energy, inflation, or faster-than-light expansion.

Neural-Network Emulator for Reionization and Optical depth

Novel cosmological framework unifying dark matter and dark energy through organizational coherence

A speculative cosmological framework without dark matter, based on frozen light, gliding structures, and an active time field. Includes mathematical validation and falsifiability tools. English version of the full VLCC model by Frédérick Vronsky.

Repository for the paper “Testing CPT–Symmetric Siamese Universes through FRB–QSO Sky Correlations (v1.3)”. Cross-correlates CHIME/FRB Catalog 1 with DESI DR1 QSOs to probe directional asymmetry near the CPT axis (RA ≈ 170°, Dec ≈ 40°), finding a marginal excess (Z = 7.0 ± 1.1, p ≈ 0.019).

Computational proof of the Schwarzschild metric in Python — GR time dilation derivation, orbital trajectory simulation, gravitational redshift calculation, and numerical relativity visualisation.
