CIAO: Chandra's Data Analysis System for X-Ray Astronomy and Beyond
Antonella Fruscione, Jonathan McDowell, Douglas Burke +13
The Chandra Interactive Analysis of Observations (CIAO) software, developed by the Chandra X-ray Center, has been the data analysis package for the Chandra X-ray Observatory since…
Transmission grating arrays for the X-ray spectrometer on Arcus Probe
Ralf K. Heilmann, Alexander R. Bruccoleri, James A. Gregory +6
The Arcus Probe mission concept has been submitted as an Astrophysics Probe Explorer candidate. It features two co-aligned high-resolution grating spectrometers: one for the soft x…
The life cycle of stars and their planets from the high energy perspective
Lia Corrales, Keivan G. Stassun, Tim Cunningham +19
One of the key research themes identified by the Astro2020 decadal survey is Worlds and Suns in Context. The Advanced X-ray Imaging Satellite (AXIS) is a proposed NASA APEX mission…
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…
How to organize an online conference -- Lessons learned from Cool Stars 20.5 (virtually cool)
Hans Moritz Günther, James R. A. Davenport, Scott Wolk +1
The virtual meeting was a success. Several people told us that this was "the best virtual meeting they had seen so far", which, a year into the pandemic and without a commercial pr…
Change point detection and image segmentation for time series of astrophysical images
Cong Xu, Hans Moritz Günther, Vinay L. Kashyap +2
Many astrophysical phenomena are time-varying, in the sense that their intensity, energy spectrum, and/or the spatial distribution of the emission suddenly change. This paper devel…
A Small Satellite Version of a Broad-band Soft X-ray Polarimeter
Herman L. Marshall, Sarah N. T. Heine, Alan Garner +16
We describe a new implementation of a broad-band soft X-ray polarimeter, substantially based on a previous design. This implementation, the Pioneer Soft X-ray Polarimeter (PiSoX) i…
Lynx grating spectrometer design: Optimizing chirped transmission gratings
Hans Moritz Günther, Ralf K. Heilmann
Lynx is one of four large-mission concept studies for NASA's 2020 Decadal survey. The design reference mission includes an X-ray grating spectrometer (XGS) based on critical-angle…
Modelling telluric line spectra in the optical and infrared with an application to VLT/X-Shooter spectra
N. Rudolf, H. M. Günther, P. C. Schneider +1
Earth's atmosphere imprints a large number of telluric absorption and emission lines on astronomical spectra, especially in the near infrared, that need to be removed before analys…
