Simulate Hubble's Law — measure the expansion rate of the universe from galaxy redshift data

India Space Academy Internship Projects

This project estimates key cosmological parameters like the Hubble constant (H₀) and matter density (Ωₘ) using Type Ia supernova data. It involves distance modulus fitting, cosmological model calculations, and analysis of low-z and high-z supernova subsets.

A python package to calibrate levitt law

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.
