|Abstract: The galaxy clustering bispectrum, i.e. the Fourier transform of the 3-point correlation function of the galaxy density field, contains a large amount of information on the cosmology and can be used to greatly improve the constraints obtained from the 2-point function alone. However, providing a covariance matrix for it can be a challenging task as a great amount of simulations are needed in order to accurately estimate it numerically. In the presentation I'm going to show my latest results towards an analytical understanding of the bispectrum covariance, accounting for non-linear and window effects.
