cooltools - Practical Tools for Scientific Computation and Visualisation

Provides utilities for scientific computation and visualisation, with an emphasis on applications in physics and astrophysics. Functionality includes random sampling from spherical and custom distributions, information and entropy analysis, Fourier transforms, two-point correlation estimation, binning and gridding of point sets, two-dimensional interpolation, Monte Carlo integration, vector operations, coordinate transformations, physical constants, and cosmological conversions. Graphics tools support the creation and export of publication-quality plots, animations, colour scales, map projections, and bitmap images. Several of these tools were used by Obreschkow et al. (2020) [doi:10.1093/mnras/staa445](doi:10.1093/mnras/staa445).

rglplus - Extension of the 'rgl' 3D Visualization Package

Provides 3D plotting routines that facilitate the use of the 'rgl' package and extend its functionality. For example, the routines allow the user to directly control the camera position & orientation, as well as to generate 3D movies with a moving observer.

nbody - Gravitational N-Body Simulation

Run simple direct gravitational N-body simulations. The package can access different external N-body simulators (e.g. GADGET-4 by Springel et al. (2021) <doi:10.48550/arXiv.2010.03567>), but also has a simple built-in simulator. This default simulator uses a variable block time step and lets the user choose between a range of integrators, including 4th and 6th order integrators for high-accuracy simulations. Basic top-hat smoothing is available as an option. The code also allows the definition of background particles that are fixed or in uniform motion, not subject to acceleration by other particles.
