Code and Data for "Evidence for Orthogonal Cosmological Axes in Radio and Gravitational-Wave Data"

This repository contains the full Google Colab notebook and supporting scripts used to produce all results, figures, and tables in Evidence for Orthogonal Cosmological Axes in Radio and Gravitational-Wave Data (Morton, 2025).The analysis performs a counts–in–cells dipole measurement of the NVSS (1.4 GHz), TGSS ADR1 (150 MHz), and the more recent LoTSS DR2 (144 MHz) public radio surveys via live VizieR queries. It evaluates the dipole amplitude vs. kinematic expectation as a function of flux threshold and implements two pre-registered null tests (GW–axis hemispherical asymmetry and patchwise local dipole clustering).All parameters, cuts, and query settings match those in the paper, with the exception of the newly added LoTSS DR2 dataset, which provides a modern complement to the NVSS and TGSS measurements. Running the notebook reproduces Figures 1–2 and Tables 1–2 exactly.
