Kavli Affiliate: Mark Schattenburg | Summary:Astronomical imaging with micro-arcsecond ($μ$as) angular resolution could enable breakthrough scientific discoveries. Previously-proposed $μ$as X-ray imager designs have been interferometers with limited effective collecting area. Here we describe X-ray telescopes achieving diffraction-limited performance over a wide energy band with large effective area, employing a nested-shell architecture with grazing-incidence mirrors, while […]
