Interactive research
The lab
Small, inspectable demonstrations of the methods behind the papers and software. Change assumptions, follow the intermediate quantities, and see how each model produces its observable result.
Watch a surrogate learn
Replay a Gaussian-process active-learning run and inspect how uncertainty guides expensive evaluations.
Open GPry lab →02 · Early universePaint a primordial spectrum
Draw a curvature spectrum and calculate the induced gravitational-wave response with SIGWAY kernels, up to 100 bins.
Open SIGWAY lab →03 · PTA populationsBuild a binary population
Change the cosmic black-hole-binary population and see its source distribution and nanohertz signal respond.
