Reconstruction of small-scale galaxy cluster substructure with lensing flexion
Benjamin Cain, Marusa Bradac, Rebecca Levinson
We present a reconstructions of galaxy-cluster-scale mass distributions from simulated gravitational lensing data sets including strong lensing, weak lensing shear, and measurement…
Analytic PSF Correction for Gravitational Flexion Studies
Rebecca Sobel Levinson
Given a galaxy image, one cannot simply measure its flexion. An image's spin one and three shape properties, typically associated with F- and G-flexion, are actually complicated fu…
Generic Misalignment Aberration Patterns and the Subspace of Benign Misalignment
Paul L. Schechter, Rebecca Sobel Levinson
Q1: Why deploy N wavefront sensors on a three mirror anastigmat (TMA) and not N + 1? Q2: Why measure M Zernike coefficients and not M + 1? Q3: Why control L rigid body degrees of f…
Generic Misalignment Aberration Patterns in Wide-Field Telescopes
Paul L. Schechter, Rebecca Sobel Levinson
Axially symmetric telescopes produce well known "Seidel" off-axis third-order aberration patterns: coma, astigmatism, curvature of field and distortion. When axial symmetry is brok…
