Hierarchical Bayesian inference of photometric redshifts with stellar population synthesis models

Boris Leistedt, Justin Alsing, Hiranya Peiris +2

We present a Bayesian hierarchical framework to analyze photometric galaxy survey data with stellar population synthesis (SPS) models. Our method couples robust modeling of spectra…

Forward modeling of galaxy populations for cosmological redshift distribution inference

Justin Alsing, Hiranya Peiris, Daniel Mortlock +2

We present a forward modeling framework for estimating galaxy redshift distributions from photometric surveys. Our forward model is composed of: a detailed population model describ…
