Optical design of diffraction-limited X-ray telescopes
Brandon D. Chalifoux, Ralf K. Heilmann, Herman L. Marshall +1
Astronomical imaging with micro-arcsecond (as) angular resolution could enable breakthrough scientific discoveries. Previously-proposed as X-ray imager designs have been inte…
Demonstration of resolving power for a space-based x-ray transmission grating spectrometer
Ralf K. Heilmann, Jeffery Kolodziejczak, Alexander R. Bruccoleri +2
We present measurements of the resolving power of a soft x-ray spectrometer consisting of 200 nm-period lightweight, alignment-insensitive critical-angle transmission (CAT) grating…
Structure and Evolution of Pre-Main Sequence Stars
Norbert S. Schulz, Glenn Allen, Mark W. Bautz +28
Low-mass pre-main sequence (PMS) stars are strong and variable X-ray emitters, as has been well established by EINSTEIN and ROSAT observatories. It was originally believed that thi…
Distribution and Structure of Matter in and around Galaxies
Norbert S. Schulz, Glenn Allen, Mark W. Bautz +24
Understanding the origins and distribution of matter in the Universe is one of the most important quests in physics and astronomy. Themes range from astro-particle physics to chemi…
