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

Geometric Information Field Theory. 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

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

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.

Unified Information-Density Theory v3.9 - Vacuum Information Density as the Fundamental Geometric Scalar: A Proposed Theoretical Framework for the Yang-Mills Mass Gap and Gamma-Scaling Unification

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

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

This program classifies the universe as flat, open, or closed based on the matter density parameter (Ωₘ) and dark energy density parameter (ΩΛ). The user enters the Hubble constant, Ωₘ, and ΩΛ, and the program uses these to determine the universe’s geometry.

From Uncertainty to Mass — interactive companion to four research papers on stochastic spacetime (Pilipović, 2023–2026). 346 tests, code-split lazy loading, hover cross-references, and a cinematic black hole descent.
