Astro2020 Science White Paper: Probing the Structure of Interstellar Dust from Micron to Kpc Scales with X-ray Imaging
Lynne Valencic, Lia Corrales, Sebastian Heinz +8
The X-ray regime is a largely underused resource for constraining interstellar dust grain models and improving our understanding of the physical processes that dictate how grains e…
Astro 2020: Astromineralogy of interstellar dust with X-ray spectroscopy
Lia Corrales, Lynne Valencic, Elisa Costantini +16
X-ray absorption fine structure (XAFS) in the 0.2-2 keV band is a crucial component in multi-wavelength studies of dust mineralogy, size, and shape -- parameters that are necessary…
A Search for H I Lyman Counterparts to Ultra-Fast X-ray Outflows
G. A. Kriss, J. C. Lee, A. Danehkar
Prompted by the H I Ly absorption associated with the X-ray ultra-fast outflow at -17,300 in the quasar PG~1211+143, we have searched archival UV spectra at the…
Discovery of an Ultraviolet Counterpart to an Ultra-Fast X-ray Outflow in the Quasar PG1211+143
Gerard A. Kriss, Julia C. Lee, Ashkbiz Danehkar +5
We observed the quasar PG1211+143 using the Cosmic Origins Spectrograph on the Hubble Space Telescope in April 2015 as part of a joint campaign with the Chandra X-ray Observatory a…
The Ultra-Fast Outflow of the Quasar PG 1211+143 as Viewed by Time-Averaged Chandra Grating Spectroscopy
Ashkbiz Danehkar, Michael A. Nowak, Julia C. Lee +8
We present a detailed X-ray spectral study of the quasar PG 1211+143 based on Chandra High Energy Transmission Grating Spectrometer (HETGS) observations collected in a multi-wavele…
MPI_XSTAR: MPI-based Parallelization of the XSTAR Photoionization Program
Ashkbiz Danehkar, Michael A. Nowak, Julia C. Lee +1
We describe a program for the parallel implementation of multiple runs of XSTAR, a photoionization code that is used to predict the physical properties of an ionized gas from its e…
