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

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.

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 v10: An Independent Metric for Porous Singularities in Compact Objects A self-contained, GR-compatible framework that redefines the event horizon as an absolute curvature boundary (r_h^eff) where tidal forces and rotation induce spacetime "smearing." No exotic matter required. Key features: - Entropy reduction to ~6.5% of Bekenstein-Hawking (

Fisher Matrix codes for IM and cross-correlations

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.

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.

Repository for the Phase-Bifurcation Cosmogenesis model. Includes, academic paper, reproducible Δϕ simulations, numerical scripts, critical-mass analysis (mϕ,crit ≈ 1.965), and visualizations of a non-singular CPT-symmetric cosmic origin.

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

Animations and plots illustrating homogeneous cosmology within different models

Foundational version of The Siamese Big Bang, introducing a directional CPT-symmetric topology inferred from CHIME/FRB data (N=100, DM≥800, |b|>20°). Shows morphological but marginal evidence (A≈90 pc cm⁻³, φ₀≈155°, p≈0.1) for a cosmological anisotropy along the Siamese axis.
