Path-tracing Monte Carlo Library for 3D Radiative Transfer in Highly Resolved Cloudy Atmospheres [PDF]
, 2019 Interactions between clouds and radiation are at the root of many difficulties in numerically predicting future weather and climate and in retrieving the state of the atmosphere from remote sensing observations. The large range of issues related to these

Ray-optical refraction with confocal lenslet arrays [PDF]
, 2008 Two parallel lenslet arrays with focal lengths f1 and f2 that share a common focal plane (that is, which are separated by a distance f1+f2) can refract transmitted light rays according to Snell's law, but with the 'sin's replaced with 'tan's. This is the

RELXILL_NK: A Black Hole Relativistic Reflection Model for Testing General Relativity
Proceedings, 2019 In this paper, we briefly present relxill_nk, the first and currently only readily available model of the relativistic reflection spectrum of black hole accretion disks that includes non-Kerr solutions for the black hole spacetime, thus allowing for ...

Ray-optical negative refraction and pseudoscopic imaging with Dove-prism arrays [PDF]
, 2008 A sheet consisting of an array of small, aligned Dove prisms can locally (on the scale of the width of the prisms) invert one component of the ray direction.

Image Ellipticity from Atmospheric Aberrations [PDF]
, 2007 We investigate the ellipticity of the point-spread function (PSF) produced by imaging an unresolved source with a telescope, subject to the effects of atmospheric turbulence.

Geant4 simulations of soft proton scattering in X-ray optics. A tentative validation using laboratory measurements [PDF]
, 2017 Low energy protons (< 300 keV) can enter the field of view of X-ray space telescopes, scatter at small incident angles, and deposit energy on the detector, causing intense background flares at the focal plane or in the most extreme cases, damaging the X ...
