Query: Leveraging High Resolution Spectra to Understand Black Hole Spectra   For the past 17 years, both XMM-Newton and Chandra have brought the powerful
combination of high spatial and spectral resolution to the study of black hole
systems. Each of these attributes requires special consideration--- in
comparison to lower spatial resolution, CCD quality spectra--- when modeling
observations obtained by these spacecraft. A good understanding of the high
resolution spectra is in fact required to model properly lower resolution CCD
spectra, with the Reflection Grating Spectrometer (RGS) instrument on
XMM-Newton maintaining the highest "figure of merit" at soft X-ray energies for
all missions flying or currently planned for the next decade. Thanks to its
even higher spectral resolution, the use of Chandra-High Energy Transmission
Gratings (HETG), albeit with longer integration times, allows for one to bring
further clarity to RGS studies. A further promising route for continued studies
is the combination of high spectral resolution at soft X-rays, via RGS and/or
HETG, with contemporaneous broadband coverage extending to hard X-rays (e.g.,
NuSTAR or INTEGRAL spectra). Such studies offer special promise for answering
fundamental questions about accretion in black hole systems; however, they have
received only moderate consideration to date. This may be due in part to the
difficulty of analyzing high resolution spectra. In response, we must continue
to develop software tools that make the analysis of high resolution X-ray
spectra more accessible to the wider astrophysics community.
