Shear measurement bias due to spatially varying spectral energy distributions in galaxies

Kavli Affiliate: Patricia Burchat | Summary:Galaxy color gradients – i.e., spectral energy distributions that vary across the galaxy profile – will impact galaxy shape measurements when the modeled point spread function (PSF) corresponds to that for a galaxy with spatially uniform color. This paper describes the techniques and results of a study of the expected […]

AMS-100: The Next Generation Magnetic Spectrometer in Space — An International Science Platform for Physics and Astrophysics at Lagrange Point 2

Kavli Affiliate: Scott P. Wakely | Summary:The next generation magnetic spectrometer in space, AMS-100, is designed to have a geometrical acceptance of $100,mathrmm^2,mathrmsr$ and to be operated for at least ten years at the Sun-Earth Lagrange Point 2. Compared to existing experiments, it will improve the sensitivity for the observation of new phenomena in cosmic […]
