Informed total-error-minimizing priors: Interpretable cosmological parameter constraints despite complex nuisance effects
Bernardita Ried Guachalla, Dylan Britt, Daniel Gruen +1
While Bayesian inference techniques are standard in cosmological analyses, it is common to interpret resulting parameter constraints with a frequentist intuition. This intuition ca…

Bounds on galaxy stochasticity from halo occupation distribution modeling
Dylan Britt, Daniel Gruen, Oliver Friedrich +2
The joint probability distribution of matter overdensity and galaxy counts in cells is a powerful probe of cosmology, and the extent to which variance in galaxy counts at fixed mat…
