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.

Relativistic effects in ultra-large-scale galaxy clustering

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.

Fisher Matrix codes for IM and cross-correlations

Final release (v1.7) of the Rotational Hemispheric Test project, expanding the v1.1 results and confirming a significant azimuthal anisotropy of FRB dispersion measures around the Siamese CPT-symmetric axis (RA = 170°, Dec = 40°). Includes full data, code, and figures.

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.

Cosmology
