An automated method for finding the most distant quasars
Lena Lenz, Daniel J. Mortlock, Boris Leistedt +2
Upcoming surveys such as Euclid, the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) and the Nancy Grace Roman Telescope (Roman) will detect hundreds of high-red…
Data-Space Validation of High-Dimensional Models by Comparing Sample Quantiles
Stephen Thorp, Hiranya V. Peiris, Daniel J. Mortlock +3
We present a simple method for assessing the predictive performance of high-dimensional models directly in data space when only samples are available. Our approach is to compare th…
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…
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…
redMaGiC: Selecting Luminous Red Galaxies from the DES Science Verification Data
E. Rozo, E. S. Rykoff, A. Abate +84
We introduce redMaGiC, an automated algorithm for selecting Luminous Red Galaxies (LRGs). The algorithm was specifically developed to minimize photometric redshift uncertainties in…
Analysing the polarisation of the CMB with spin scale-discretised wavelets
Boris Leistedt, Jason D. McEwen, Martin Büttner +3
We discuss a new scale-discretised directional wavelet transform to analyse spin signals defined on the sphere, in particular the polarisation of the cosmic microwave background (C…
On spin scale-discretised wavelets on the sphere for the analysis of CMB polarisation
Jason D. McEwen, Martin Büttner, Boris Leistedt +3
A new spin wavelet transform on the sphere is proposed to analyse the polarisation of the cosmic microwave background (CMB), a spin signal observed on the celestial sphere.…
