Rapid and robust simulation-based inference for kilonovae
Stephanie M. Brown, Mattia Bulla, Hiranya V. Peiris +6
With the next generation of both electromagnetic and gravitational wave observatories beginning to come online, rapid analysis methods for kilonova data are becoming increasingly i…
An approach to robust Bayesian regression in astronomy
William Martin, Daniel J. Mortlock
Model mis-specification (e.g. the presence of outliers) is commonly encountered in astronomical analyses, often requiring the use of ad hoc algorithms which are sensitive to arbitr…
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…
