N-body code for cosmological structure formation in cubic vector Galileon gravity

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

Cosmological analyses of f(R) theories using MCMC

Constructs neutron star models in the context of regularized 4D Einstein-Gauss-Bonnet gravity, using the KEH/CST numerical scheme.

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

Source code for the article PhysRevD.105.123531 entitled "Forecasting F(Q) cosmology with ΛCDM background using standard sirens".

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.

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 reinterpreted as a gravitational soliton. Explains 650 km/s velocity with cold gas via metric shock, not thermal. Calibrated from GNSS data. Paper 8 of the TEP series.

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

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

Reinterprets dark matter observations as phantom mass from temporal shear in gravitational lensing. Conformal metric coupling creates temporal composite images, generating gravitational shear signatures. Resolves strong lensing time delays and core-cusp problem. TEP Paper 4.

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

Universal Critical Density: Unifying atomic, galactic, and compact object scales via gravitational solitons. Derives ρ_c ≈ 20 g/cm³ from GNSS clocks, validates across SPARC galaxies, magnetars, and Milky Way. TEP Paper 7.

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.

Covariant reformulation of relativity with dynamic time as a field and emergent light speed. Proposes two-metric geometry (gravitational + causal), synchronization holonomy as key observable, and falsifiable experimental tests. Addresses cosmological tensions while preserving local Lorentz invariance.

Scripts and environments for performing parameter inference from cosmological surveys, specifically using the DESILIKE and Cosmoprimo packages and the modified folps code for modified gravity analysis.

Code & data reproducing the Siamese Interference Cosmology analysis against Son & Lee (2025). We show that cosmic deceleration (q0​>0) emerges naturally from phase interference, predicting a falsifiable hemispheric anisotropy for Euclid/LSST.

We study the Swampland criteria for canonical scalar potentials for the case of a rescaled f(R) gravity under the assumption that a Parity odd string corretive term is present.
