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.

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.

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.

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

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.
