Fast Calculation of Nonlinear Redshift-space Galaxy Power Spectrum
  Including Selection Bias
  We present a fast implementation of the next-to-leading order (1-loop)
redshift-space galaxy power spectrum by using FFTlog-based methods. [V.
Desjacques, D. Jeong, and F. Schmidt, JCAP 1812 (12), 035] have shown that the
1-loop galaxy power spectrum in redshift space can be computed with 28
independent loop integrals with 22 bias parameters. Analytical calculation of
the angular part of the loop integrals leaves the radial part in the form of a
spherical Bessel transformation that is ready to be integrated numerically by
using the FFTLog transformation. We find that the original 28 loop integrals
can be solved with a total of 85 unique FFTLog transformations, yet leading to
a few orders of magnitude speed up over traditional multi-dimensional
integration. The code used in this work is publicly available at
