Disentangling Multiple Gas Kinematic Drivers in the Perseus Galaxy Cluster
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +143
Galaxy clusters, the Universe's largest halo structures, are filled with 10-100 million degree X-ray-emitting gas. Their evolution is shaped by energetic processes such as feedback…
Line Ratios for Solar Wind Charge Exchange with Comets
P. D. Mullen, R. S. Cumbee, D. Lyons +4
Charge exchange (CX) has emerged in X-ray emission modeling as a significant process that must be considered in many astrophysical environment--particularly comets. Comets host an…
Ne X X-ray Emission due to Charge Exchange in M82
R. S. Cumbee, L. Liu, D. Lyons +4
Recent X-ray observations of star-forming galaxies such as M82 have shown the Ly beta/Ly alpha line ratio of Ne X to be in excess of predictions for thermal electron impact excitat…
Charge Exchange Induced X-ray Emission of Fe XXV and Fe XXVI via a Streamlined Model
P. D. Mullen, R. S. Cumbee, D. Lyons +1
Charge exchange is an important process for the modeling of X-ray spectra obtained by the Chandra, XMM-Newton, and Suzaku X-ray observatories, as well as the anticipated Astro-H mi…
A novel scenario for the possible X-ray line feature at ~3.5 keV: Charge exchange with bare sulfur ions
L. Gu, J. Kaastra, A. J. J. Raassen +4
Motivated by recent claims of a compelling ~3.5 keV emission line from nearby galaxies and galaxy clusters, we investigate a novel plasma model incorporating a charge exchange comp…
Can Charge Exchange Explain Anomalous Soft X-ray Emission in the Cygnus Loop?
Renata S. Cumbee, David B. Henley, Phillip C. Stancil +4
Recent X-ray studies have shown that supernova shock models are unable to satisfactorily explain X-ray emission in the rim of the Cygnus Loop. In an attempt to account for this ano…
