a list of useful tools, apps and publicly available codes
Explore lensing by a tidally truncated NFW subhalo inside a larger host. Calculate radial and tangential caustic areas, and animate how the caustics change with distance from the host center.
Explore Substructure Lensing ↗Follow the density, mass, and velocity dispersion of an evolving self-interacting dark matter halo as it undergoes gravothermal core collapse. Explore how core collapse changes as it transitions from the long to short mean free path regimes.
Explore SIDM core collapse ↗Explore gravitational lensing during the collapse of self-interacting dark-matter halos. Adjust halo and source properties, then watch evolving profiles, lensed images, and magnification.
Explore SIDM lensing lab ↗Build anisotropic spherical equilibrium models for dark-matter halos, galaxies, and star clusters. This Python toolkit constructs distribution functions, generates particle initial conditions, and predicts velocity observables, with self-consistent truncation in phase space.
Explore PIANISTpy ↗Can AI carry out a research project with minimal supervision? On September 20, 2026, we gave Codex two days to devise a galactic-bars project, conduct the research, and publish its findings. Explore the results.
