On approximations of the redshift-space bispectrum and power spectrum multipoles covariance matrix
Sergi Novell-Masot, Héctor Gil-Marín, Licia Verde
We investigate, in dark matter and galaxy mocks, the effects of approximating the galaxy power spectrum-bispectrum estimated covariance as a diagonal matrix, for an analysis that a…

GEO-FPT: a model of the galaxy bispectrum at mildly non-linear scales
Sergi Novell-Masot, Davide Gualdi, Héctor Gil-Marín +1
We present GEO-FPT (Geometric Fitted Perturbation Theory), a new model for the galaxy bispectrum anisotropic signal in redshift space, with functional form rooted in perturbation t…
