RotVis
Compare an idealized rotating disk with a two-component merger while changing inclination, velocity separation, spatial resolution, and spectral resolution.

Small tools for building intuition about galaxy kinematics and scale-dependent velocity statistics.
Power spectrum and variance
Connect annular-mean power, variance per logarithmic scale, beam suppression, and cumulative velocity variance without confusing their definitions.
Explore spatial scalesVelocity harmonics
See how harmonic order controls the number and orientation of positive and negative line-of-sight velocity regions around a galactic ring.
