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

Python code for learning cosmology using different methods and mock data

The numerical analysis files corresponding to arxiv: 2202.00962

Relativistic effects in ultra-large-scale galaxy clustering

This repository contains files related to the Python programming workshop conducted for astrophysics and cosmology work at Nagpur. The repository includes sample codes, datasets, and presentations used during the workshop. These materials can be useful for beginners who want to learn Python programming for astrophysics and cosmology work.

Main tools and results from arxiv:

Physique du plasma primordial et simulation de coupe 2D des fluctuations du CMB en fonction de l'indice spectral

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.

HSE Unification: From Porous Black Holes to Cosmological Cohesion. Comprehensive Derivation of Hograefe-Singularity-Entropy (v1.0 – v10.5) The Hograefe-Singularity-Entropy (HSE) framework replaces the classical point singularity with a thermodynamically consistent porous spacetime structure.

Bayesian MCMC inference of Early Quintessence parameters from Planck 2018 CMB bandpowers

Fisher Matrix codes for IM and cross-correlations

The files corresponding to arxiv:2004.02155

🔍 Explore the critical phase mass in CPT-symmetric “Siamese Universes” with reproducible results, including analysis scripts and figure assets.

This essay presents a clear and intuitive overview of the full Siamese Universe framework. It explains how a shared quantum vacuum, a minimal phase desynchronization, and CPT symmetry together generate matter, structure, and cosmic complexity. A causal narrative linking physical principles and observable signatures.

Cosmic Causal Velocity at Total Binary Epoch #202 for Resonance Harmonics Medicine Equation

The codes for computing the scale-dependent peak height function and the scale-dependent valley depth function of the cosmic-log density field.

Comparative cosmology framework showing how CPT-Siamese phase dynamics resolves the main failures of ΛCDM: H₀ tension, σ₈ tension, Axis of Evil, JWST early galaxies and vacuum energy. Includes analytic model, toy simulations, and H(z), q(z) figures. Open reproducible science.

The universe may operate as a self-executing algorithm where structure precedes matter. Reality’s “errors”—from cosmic anomalies to quantum correlations—are reflections of its code. Through holography, recursion, and informational self-replication, the cosmos continuously rewrites its own laws.
