phasecurvefit
The phasecurvefit logo: noisy points along a self-crossing looped curve, coloured by their fitted order from red through yellow to blue, with the learned mean path drawn as a black line.

Paths through phase space

Fit a curve through phase-space points — streams, orbits, trajectories.

}
potamides
The potamides logo: a capital Phi, for the gravitational potential, its ring a stream of stars shaded teal into purple with three arrows a side pointing in, on a dark rounded square.

co-lead developer

Constrain gravitational potentials from stellar stream curvature

A JAX package that fits stream tracks with splines and compares their curvature directly to a potential's accelerations. Co-led with Sirui Wu.

}
galax
The galax logo, the GalacticDynamics mark: a painted spiral galaxy with a glowing core on a dark disk, circled by a dark ring, between a teal < and a purple > code bracket.

lead developer

Galactic dynamics in JAX

Orbit integration, potentials and stream generation — GPU-accelerated and fully differentiable.

}
coordinax
The coordinax logo: a ruler crossed with a green arrow on a blue square.

lead developer

Coordinates in JAX

Vectors, frames and transformations — differentiable, and unit-aware via unxt.

unxt
The unxt logo: a ruler crossed with a green pencil on a blue square.

lead developer

Units in JAX

Unit-aware quantities that survive jit, grad and vmap.
