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

High-performance, multithreaded C++ library with a Python interface designed for the rapid visualization of Smoothed Particle Hydrodynamics (SPH) simulations.

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

Analytic and numeric reference solutions for comoving magnetohydrodynamic waves

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

Starflood is a free & open-source astrophysical simulation code hand-written in C.

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

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).

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

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

parallel implementations of n-body simulation methods, (naive and Barnes-Hut) on GPU (via C and OpenCL)

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.

Simple cosmological simulations.

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

Utilities for working with catalogs (mostly Raygal lightcones) and perform basic cosmology computations such as distances, volumes, growth factor, growth rate, P(k)-xi etc...

OpenCL many-body gravity simulator with particle collision and coalescence

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

z_cats is a visualisation and data extraction package for cosmological zoom in simulations using Arepo, it can also be used to compute certain parameters to set up MUSIC parameter files for cosmological zoom in initial condition generation.
