A Visual Guide to Planetary Microlensing
Leslie A. Rogers, Paul L. Schechter
The microlensing technique has found 10 exoplanets to date and promises to discover more in the near future. While planetary transit light curves all show a familiar shape, planeta…
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…
A doubled double hotspot in J0816+5003 and the logarithmic slope of the lensing potential
Katherine Blundell, Paul Schechter, Nick Morgan +3
We present an analysis of observations of the doubly-lensed double hotspot in the giant radio galaxy J0816+5003 from MERLIN, MDM, WIYN, WHT, UKIRT and the VLA. The images of the tw…
Sizes and Temperature Profiles of Quasar Accretion Disks from Chromatic Microlensing
Jeffrey A. Blackburne, David Pooley, Saul Rappaport +1
Microlensing perturbations to the flux ratios of gravitationally lensed quasar images can vary with wavelength because of the chromatic dependence of the accretion disk's apparent…
