High-resolution X-ray spectroscopic constraints on cooling-flow models for clusters of galaxies

JR Peterson, SM Kahn, FBS Paerels…�- The Astrophysical�…, 2003 - iopscience.iop.org
We present high-resolution X-ray spectra of 14 putative cooling-flow clusters of galaxies
obtained with the Reflection Grating Spectrometer on XMM-Newton. The clusters in the
sample span a large range of temperatures and mass deposition rates. Various of these
spectra exhibit line emission from O VIII, Ne X, Mg XII and XI, Al XIII and XII, Si XIV and XIII, N
VII, and C VI as well as all Fe L ions. The spectra exhibit strong emission from cool plasma at
just below the ambient temperature, T 0, down to T 0/2, but also exhibit a severe deficit of�…

High resolution X-ray spectroscopy of ζ Puppis with the XMM-Newton reflection grating spectrometer

SM Kahn, MA Leutenegger, J Cottam, G Rauw…�- Astronomy &�…, 2001 - aanda.org
We present the first high resolution X-ray spectrum of the bright O4Ief supergiant star ζ
Puppis, obtained with the Reflection Grating Spectrometer on-board XMM-Newton. The
spectrum exhibits bright emission lines of hydrogen-like and helium-like ions of nitrogen,
oxygen, neon, magnesium, and silicon, as well as neon-like ions of iron. The lines are all
significantly resolved, with characteristic velocity widths of order 1000-1500 km s-1. The
nitrogen lines are especially strong, and indicate that the shocked gas in the wind is mixed�…

High-resolution X-ray spectra of Capella: initial results from the Chandra high-energy transmission grating spectrometer

CR Canizares, DP Huenemoerder…�- The Astrophysical�…, 2000 - iopscience.iop.org
High-resolution spectra of the active binary Capella (G8 III+ G1 III) covering the energy
range of 0.4–8.0 keV (1.5–30 �) show a large number of emission lines, demonstrating the
performance of the High-Energy Transmission Grating Spectrometer. A preliminary
application of plasma diagnostics provides information on coronal temperatures and
densities. Lines arising from different elements in a range of ionization states indicate that
Capella has plasma with a broad range of temperatures, from log T= 6.3 to 7.2, generally�…
