High Resolution X-ray Spectroscopic Constraints on Cooling-Flow Models
John R. Peterson, Steven M. Kahn, Frits B. S. Paerels +5
We present XMM-Newton Reflection Grating Spectrometer observations of X-ray clusters and groups of galaxies. We demonstrate the failure of the standard cooling-flow model to descri…
Monte Carlo Methods for X-ray Dispersive Spectrometers
J. R. Peterson, J. G. Jernigan, S. M. Kahn
We discuss multivariate Monte Carlo methods appropriate for X-ray dispersive spectrometers. Dispersive spectrometers have many advantages for high resolution spectroscopy in the X-…
High Resolution Spectroscopy of 14 Cooling-Flow Clusters of Galaxies Using the Reflection Grating Spectrometers on XMM-Newton
J. R. Peterson, C. Ferrigno, J. S. Kaastra +5
We present high resolution X-ray spectra of 14 cooling-flow X-ray clusters and groups obtained with the Reflection Grating Spectrometers (RGS) on XMM-Newton. The spectra exhibit li…
Confronting atomic data with Fe L-shell spectra of stellar coronae
E. Behar, J. Cottam, J. R. Peterson +5
It is common to suggest the uncertainties in the atomic data for explaining difficulties that arise in interpreting astrophysical x-ray spectra. The atomic data for the Fe L-shell…
