large-scale structure

Tuesdays are low-research days! But I did have a good conversation with Storey-Fisher (NYU) about our correlation-function estimator, and how to precisely test it. It has so many applications! We also discussed how our three projects fit together: Correlation-function estimation, adversarial mock catalogs, and searching for anomalies in the large-scale structure. The middle project—adversarial mocks—is about making mocks that have systematics that would defeat current systematics correction, and also making methods that would defeat even those mocks.
