Description
The Beyond Two Point Galaxy Clustering Challenge
The last decade has seen significant improvements in the statistical power of galaxy survey data and in the methods for modeling such data. These improvements have motivated the development of a variety of novel techniques for analyzing this data either down to non-linear scales or beyond standard two-point statistics. We present the results of a masked "Beyond-2pt" community data challenge testing and benchmarking these techniques. The challenge dataset consists of HOD-based mock galaxy catalogues in real-space, redshift-space and on a light cone. Eight teams participated in this challenge, developing end-to-end pipelines to analyze the challenge mocks in order to constrain their unknown cosmological parameters. All teams were able to produce unbiased cosmology constraints, lending credibility to their various Beyond-2pt methods. Additionally we will present the outlook for a next generation of the Beyond-2pt challenge focused on constraints from surveys of emission line galaxies.
