The Galaxy Bispectrum in the Spherical Fourier-Bessel Basis
Joshua N. Benabou, Adriano Testa, Chen Heinrich +2
The bispectrum, the three-point correlation in Fourier space, is a crucial statistic for studying many effects targeted by the next-generation galaxy surveys, such as primordial no…

Validation of Spherical Fourier-Bessel power spectrum analysis with lognormal simulations and eBOSS DR16 LRG EZmocks
Henry Grasshorn Gebhardt, Olivier Doré
Tuning into the bass notes of the large-scale structure requires careful attention to geometrical effects arising from wide angles. The spherical Fourier-Bessel (SFB) basis provide…
