Spurious correlations between galaxies and multi-epoch image stacks in the DESI Legacy Surveys
Edgar Eggert, Boris Leistedt
A non-negligible source of systematic bias in cosmological analyses of galaxy surveys is the on-sky modulation caused by foregrounds and variable image characteristics such as obse…
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…
Mapping Interstellar Dust with Gaussian Processes
Andrew C. Miller, Lauren Anderson, Boris Leistedt +3
Interstellar dust corrupts nearly every stellar observation, and accounting for it is crucial to measuring physical properties of stars. We model the dust distribution as a spatial…
