X-ray grating spectroscopy as a mission enhancement
Hans Moritz Guenther, Ehud Behar, Joel N. Bregman +27
We propose to add instruments to any potential future X-ray mission with focussing optics that is considered in NASA's ASTRA framework. Such an instrument is a necessity to study A…
Concept of a Double Tilted Rowland Spectrograph for X-rays
Hans Moritz Günther, Casey T. DeRoo, Ralf K. Heilmann +1
High-resolution spectroscopy in soft X-rays ( keV) requires diffractive elements to resolve any astrophysically relevant diagnostics, such as closely spaced lines, weak absorpt…
Arcus X-ray telescope performance and alignment
Hans Moritz Günther, Peter Cheimets, Eric D. Miller +4
Arcus is a concept for a probe class mission to deliver high-resolution FUV and X-ray spectroscopy. For X-rays, it combines cost-effective silicon pore optics (SPO) with high-throu…
X-ray performance of critical-angle transmission grating prototypes for the Arcus mission
Ralf K. Heilmann, Alexander R. Bruccoleri, Vadim Burwitz +12
Arcus is a proposed soft x-ray grating spectrometer Explorer. It aims to explore cosmic feedback by mapping hot gases within and between galaxies and galaxy clusters and characteri…
Searching for outliers in the Chandra Source Catalog
Dustin K. Swarm, Casey T. DeRoo, Yanan Liu +1
Astronomers are increasingly faced with a deluge of information, and finding worthwhile targets of study in the sea of data can be difficult. Outlier identification studies are a m…
Metrology for Measuring Custom Periodicities on Diffraction Gratings
Ningxiao Zhang, Randall McEntaffer, Ross McCurdy +1
We present a new, inexpensive, bench-top method for measuring groove period over large areas with high mapping resolution and high measurement accuracy, dubbed the grating mapper f…
