DISCO-DJ: DIfferentiable Simulations for COsmology - Done with Jax

A set of tools, codes, and methodologies for cosmology

This is a simple framework to numerically simulate inflationary dynamics in the early universe.

Implements Helmholtz-Hodge decomposition for an AMR velocity field

Codes to generate fast HI field-level mocks in real and redshift space

Open-source SPH and N-body code written in C/C++

Heavily modified version of GABE C++ code for paper https://arxiv.org/abs/2007.10978. Solves coupled differential equations for early universe reheating on finite spatial lattice. Plus helpful mathematica noteboks (made by me).

Analytic and numeric reference solutions for comoving magnetohydrodynamic waves

Implements 3D point cloud algorithms for estimation and fitting of shape and density profiles

Python wrapper of Effective Zel'dovich approximation mock (EZmock)

OpenCL many-body gravity simulator with particle collision and coalescence

This is the public repository for the Kun simulation suite, which is utilized for the CSST Emulator.

The Python module that used to measure the environment-dependent Wavelet Power Spectrum (env-WPS) of the cosmic density field.

Simple cosmological simulations.

These documents investigate key characteristics of galaxy clusters found in TNG illustris simulations. This work was performed as part of my summer research with Simons Observatory as an NSBP scholar.

A framework for generating deep-learning SKA radio telescope & cosmological hydrodynamical simulation data

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.

An online resume and portfolio showcasing my projects, skills, and experiences. You can learn more about me and my work here.

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

Reproducible study of the Phase-Bifurcation model in Siamese cosmology. A scan over (mϕ, krot) shows a sharp transition in PA with a robust critical mass mϕ,crit ≃ 1.965; rotation is a weak, near-vertical modulation. Includes separatrix, phase portraits, trajectories, and a data/repro section (thresholds, seed, integrator, N-windows).
