Adaptive Reconstruction of Cluster Halos (ARCH): Integrating Shear and Flexion for Substructure Detection
Jacob Shpiece, David M. Goldberg
We present ARCH (Adaptive Reconstruction of Cluster Halos), a new gravitational lensing pipeline for cluster mass reconstruction that applies a joint shear-flexion analysis to JWST…
Bayes' Theorem, Inflation, and the Ekpyrotic Universe
Joseph Wraga, David M. Goldberg
We calculate the Bayesian evidences for a class of Ekpyrotic universe models, and compare with a model of single field inflation with a Higgs-type potential. Combining parsimony an…
Cosmic flexion
Evan J. Arena, David M. Goldberg, David J. Bacon
Cosmic flexion, like cosmic shear, is a correlation function whose signal originates from the large-scale structure of the universe. Building on the observational success of cosmic…
A New Estimate of Galaxy Mass-to-Light Ratios from Flexion Lensing Statistics
Joseph Michael Fabritius, David M Goldberg
We perform a flexion based weak gravitational analysis of the first two Hubble Frontier Field clusters: Abell 2744 and MACS 0416. A parametric method for using projected flexion si…
Flat Maps that improve on the Winkel Tripel
J. Richard Gott, David M. Goldberg, Robert J. Vanderbei
Goldberg & Gott (2008) developed six error measures to rate flat map projections on their verisimilitude to the sphere: Isotropy, Area, Flexion, Skewness, Distances, and Boundary C…
Shape, Color and Distance in Weak Gravitational Flexion
Joseph M. Fabritius, Evan J. Arena, David M. Goldberg
Canonically, elliptical galaxies might be expected to have a perfect rotational symmetry, making them ideal targets for flexion studies - however, this assumption hasn't been teste…
