Matter bispectrum of large-scale structure with Gaussian and non-Gaussian initial conditions: Halo models, perturbation theory, and a three-shape model
Andrei Lazanu, Tommaso Giannantonio, Marcel Schmittfull +1
We study the matter bispectrum of large-scale structure by comparing the predictions of different perturbative and phenomenological models with the full three-dimensional bispectru…
Matter bispectrum of large-scale structure: Three-dimensional comparison between theoretical models and numerical simulations
Andrei Lazanu, Tommaso Giannantonio, Marcel Schmittfull +1
We study the matter bispectrum of the large-scale structure by comparing different perturbative and phenomenological models with measurements from -body simulations obtained wit…
Eulerian BAO Reconstructions and N-Point Statistics
Marcel Schmittfull, Yu Feng, Florian Beutler +2
As galaxy surveys begin to measure the imprint of baryonic acoustic oscillations (BAO) on large-scale structure at the sub-percent level, reconstruction techniques that reduce the…
