Cosmological Inference Framework Used by the Dark Energy Spectroscopic Instrument (DESI)

A collection of research notebooks in *cosmology*.

Emergent spacetime geometry from the Dirac phase field — exact N-body solutions, dark matter without new particles, quantum-corrected GR

K₇ (formerly GIFT), the founding framework of the Arithmon program. Standard Model parameters as topological invariants of a G₂ manifold. Zero free parameters, formally verified, falsifiable.

🚀 Neste projeto encontro analiticamente constantes cosmológicas do Universo a partir de um banco de dados do redshift de Super Novas do tipo Ia. Para isso foi usado o Monte Carlo da Cadeia de Markov com o fim de determinar a covariância entre diferentes grandezas e de encontrar a máxima verossimilhança de suas respectivas elipses de incertezas.

Equations of Motion from a Lagrangian of a cosmological model with fading dark matter and interacting quintessence, implemented into CLASS

Relaxation-Driven Cyclic Cosmology (RDCC) - minimal CPT-symmetric one-parameter extension of ΛCDM. Complete open-source framework: Flagship paper, MCMC fits (α = 0.0176 ± 0.0021), 100+ technical Companions on weak-lensing topology, persistent homology, neural transport maps, Fisher geometry, and end-to-end inference.

The Cascade Series: The universe from nothing

Constructed for the study of viable dark energy f(R) models and the extraction of the expected enhancement or suppression of gravitational waves.

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.

Python implementation of Damped Oscillating Dark Energy model with numerical optimization (L-BFGS-B) and Pantheon+ fitting.

Afterglow Dark Energy CLASS Repository

Python implementation of Topological Entropic Gravity (Hughes 2025) for solving S8 tension.

A novel theoretical physics framework that derives spacetime from quantum information.

Based on a Fortran code developed by Pier-Stefano Corasaniti (LUTH), the goal of this Python/C code is to provide an efficient yet easy to use library to compute the mass of the most massive galaxy cluster in a given redshift bin.
