Hamiltonian Gauge Gravity Surveyor (HiGGS). Tools for Hamiltonian constraint, canonical and Dirac-Bergmann analysis of gravity theories with spacetime curvature and torsion.

Raw RINEX validation of distance-structured correlations in GNSS atomic clocks. Detects exponential decay signatures (λ≈1-4 km) in 539 stations using SPP with broadcast ephemerides, eliminating processing artifact hypothesis. Shows E-W>N-S anisotropy, CMB alignment, orbital coupling. TEP-GNSS Paper 3.

A minimal scalar relaxation model for cosmology—no Big Bang, no dark energy, just one slow wave on an eternal lake.

Code for emulating f(R) modified gravity simulations from ΛCDM simulations using a BicycleGAN

This repository contains the Wolfram Mathematica notebooks I developed during the research for my Diploma Thesis at the School of Physics, Faculty of Sciences, A.U.Th. The Diploma Thesis is a part of a broader research, which can be found at arXiv 2105.11935. My Diploma Thesis is provided as a supplement attached to this repository.

RBH-1 runaway black hole as Temporal Topology soliton candidate. Explains 650 km/s velocity discontinuity with cold gas via metric shock. TEP calibration: R_T≈7.8×10⁷ km from GNSS. Alternative to shock physics cooling problem

Constructed for the study of viable dark energy f(R) models and the extraction of the expected enhancement or suppression of gravitational waves.

The ACM Trunk: a rigid holographic framework for galactic dynamics. This repository provides the core analytical engine for predicting galaxy rotation behavior from baryonic distributions via linear holographic screening. Tagline No galaxy-by-galaxy fits. No hidden knobs. Just the physics of the background floor.

A quick code that not only describes how the inflationary era is studied, but also manages to generate a blue tilted tensor spectral index through fine tuning.

Deterministic reproducibility capsule for GIFT Paper 1. Reproduces the deep-regime scaling and normalization of the RAR and BTFR from the SPARC dataset using fixed-slope ODR fits. Code, derived data, and verification figures included. Archived snapshot: Zenodo DOI 10.5281/zenodo.18513729.

Source code used to develop work carried out during my MSc thesis entitled 'Forecasting f(Q) Cosmology with Standard Sirens'.

Curvature-Memory Scalar-Tensor Gravity (CMSTG): four-paper journal series and simulation suite SIM80-SIM146

Universal critical density ρ_T ≈ 20 g/cm³ from R ∝ M^(1/3) scaling. GNSS-calibrated (L_c ≈ 4200 km), validated across SPARC galaxies, Milky Way, magnetars. Temporal Topology screening reconciles galactic dynamics with GR tests. TEP Paper 6.

Globular cluster pulsar spin-down anomaly: 197 cluster vs 346 field pulsars show 0.40 dex residual (8.3σ). Suppressed density scaling (Γ=0.39±0.08 vs Newtonian Γ=0.72, 4.1σ). Tests TEP observable response coefficient κ_MSP
