CMB-S4: Foreground-Cleaning Pipeline Comparison for Measuring Primordial Gravitational Waves
Federico Bianchini, Dominic Beck, W. L. Kimmy Wu +6
We compare multiple foreground-cleaning pipelines for estimating the tensor-to-scalar ratio, , using simulated maps of the planned CMB-S4 experiment within the context of the So…

: GPU Accelerated Spherical Harmonic Transforms on Arbitrary Pixelizations
Sebastian Belkner, Adriaan J. Duivenvoorden, Julien Carron +2
We present , a general-purpose Python package that wraps a highly efficient CUDA implementation of the nonuniform spin- spherical harmonic transform. The metho…
