Data Analysis Recipes: Products of multivariate Gaussians in Bayesian inferences
David W. Hogg, Adrian M. Price-Whelan, Boris Leistedt
A product of two Gaussians (or normal distributions) is another Gaussian. That's a valuable and useful fact! Here we use it to derive a refactoring of a common product of multivari…
SPECULATOR: Emulating stellar population synthesis for fast and accurate galaxy spectra and photometry
Justin Alsing, Hiranya Peiris, Joel Leja +6
We present SPECULATOR - a fast, accurate, and flexible framework for emulating stellar population synthesis (SPS) models for predicting galaxy spectra and photometry. For emulating…
Target Neutrino Mass Precision for Determining the Neutrino Hierarchy
Constance Mahony, Boris Leistedt, Hiranya V. Peiris +5
Recent works combining neutrino oscillation and cosmological data to determine the neutrino hierarchy found a range of odds in favour of the normal hierarchy. These results arise f…
Stellar mass as a galaxy cluster mass proxy: application to the Dark Energy Survey redMaPPer clusters
A. Palmese, J. Annis, J. Burgad +82
We introduce a galaxy cluster mass observable, , based on the stellar masses of cluster members, and we present results for the Dark Energy Survey (DES) Year 1 observation…
Hierarchical modeling and statistical calibration for photometric redshifts
Boris Leistedt, David W. Hogg, Risa H. Wechsler +1
The cosmological exploitation of modern photometric galaxy surveys requires both accurate (unbiased) and precise (narrow) redshift probability distributions derived from broadband…
Red clump stars and Gaia: Calibration of the standard candle using a hierarchical probabilistic model
Keith Hawkins, Boris Leistedt, Jo Bovy +1
Distances to individual stars in our own Galaxy are critical in order to piece together the nature of its velocity and spatial structure. Core helium burning red clump (RC) stars h…
