Toward a robust inference method for the galaxy bispectrum: likelihood function and model selection
Andrea Oddo, Emiliano Sefusatti, Cristiano Porciani +2
The forthcoming generation of galaxy redshift surveys will sample the large-scale structure of the Universe over unprecedented volumes with high-density tracers. This advancement w…
