Efficient Evaluation of Cosmological Angular Statistics and Cosmological Parameters with Theoretical Uncertainties in Galaxy Clustering

Abstract: In this talk I will discuss two somewhat (un)related topics. In the first part of the talk I will describe a simple trick to efficiently evaluate the power spectrum and the bispectrum of arbitrary observable projected on the sky, without using Limber or flat sky approximations. In the second part I will focus on a general question of extracting cosmological parameters using these correlation functions. I will talk about a method to consistently do data analysis keeping in mind theoretical uncertainties in our models of galaxy clustering.
