A complete FFT-based decomposition formalism for the redshift-space bispectrum
A complete FFT-based decomposition formalism for the redshift-space bispectrum
To fully extract cosmological information from nonlinear galaxy distribution in redshift space, it is essential to include higher-order statistics beyond the two-point correlation function. In this paper, we propose a new decomposition formalism for computing the anisotropic bispectrum in redshift space and for measuring it from galaxy samples. Our formalism …
