$\text{cunuSHT}$: GPU Accelerated Spherical Harmonic Transforms on Arbitrary Pixelizations

Sebastian Belkner, Adriaan J. Duivenvoorden, Julien Carron +2

We present $\text{cunusht}$, a general-purpose Python package that wraps a highly efficient CUDA implementation of the nonuniform spin-$0$ spherical harmonic transform. The metho…
