In another low-research day (it is beginning of term here) there was a great Astrophysics Seminar at NYU by Marilena Loverde (Stony Brook). She has the great capability of turning complex ideas, that are backed by cosmological simulations, into very simple conceptual arguments. And she has been doing this well for a decade now! She showed us that the bias—or the relationship between galaxies and the dark-matter field—cannot be a function of only local density (on some scale). It must also depend on the local expansion history, which depends on perturbations in the dark-matter and dark-energy-ish (quintessence) and radiation fields. This all gives me great hope for my anomalies project with Kate Storey-Fisher (NYU).
