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…
