Scalable Heteroskedastic Gaussian Process Models for Large Inhomogeneous Datasets
K. Potter, K. R. Moran, R. Ulrich +5
We introduce Heteroskedastic Normalized Vecchia Gaussian Processes (HetNV), a scalable framework for Gaussian process regression with input-dependent observation noise. HetNV combi…
Estimating Complex Densities using Two-Stage Normalizing Flows
Roxana Darvishi, David C. Stenning, Ted von Hippel +1
In many scientific applications, the target probability distribution cannot be evaluated in closed form or sampled from directly. Instead, it can often be decomposed into multiple…
Effect of Systematic Uncertainties on Density and Temperature Estimates in Coronae of Capella
Xixi Yu, Vinay L. Kashyap, Giulio Del Zanna +4
We estimate the coronal density of Capella using the O VII and Fe XVII line systems in the soft X-ray regime that have been observed over the course of the Chandra mission. Our ana…
Improved Weak Lensing Photometric Redshift Calibration via StratLearn and Hierarchical Modeling
Maximilian Autenrieth, Angus H. Wright, Roberto Trotta +3
Discrepancies between cosmological parameter estimates from cosmic shear surveys and from recent Planck cosmic microwave background measurements challenge the ability of the highly…
Updating the first CHIME/FRB catalog of fast radio bursts with baseband data
FRB Collaboration, Mandana Amiri, Bridget C. Andersen +57
In 2021, a catalog of 536 fast radio bursts (FRBs) detected with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope was released by the CHIME/FRB Collaborat…
Statistical association between the candidate repeating FRB 20200320A and a galaxy group
Masoud Rafiei-Ravandi, Kendrick M. Smith, D. Michilli +17
We present results from angular cross-correlations between select samples of CHIME/FRB repeaters and galaxies in three photometric galaxy surveys, which have shown correlations wit…
