RGS Observations of Ejecta Knots in Tycho's Supernova Remnant
Brian J. Williams, Satoru Katsuda, Renata Cumbee +3
We present results from {\it XMM-Newton/RGS} observations of prominent knots in the southest portion of Tycho's supernova remnant, known to be the remnant of a Type Ia SN in 1572 C…
Charge exchange, from the sky to the laboratory: A method to determine state-selective cross-sections for improved modeling
Gabriele L. Betancourt-Martinez, Renata S. Cumbee, Maurice A. Leutenegger
Charge exchange (CX) is a semi-resonant recombination process that can lead to spectral line emission in the X-ray band. It occurs in nearly any environment where hot plasma and co…
X-rays Studies of the Solar System
Bradford Snios, William R. Dunn, Carey M. Lisse +23
X-ray observatories contribute fundamental advances in Solar System studies by probing Sun-object interactions, developing planet and satellite surface composition maps, probing gl…
High Forbidden-to-resonance Line Ratio of OVII Discovered in the Cygnus Loop
H. Uchida, S. Katsuda, H. Tsunemi +5
Charge exchange (CX) is an important process in shock physics since it indicates an interaction between downstream ions and ambient neutral hydrogen, suggesting a presence of a col…
High-resolution Charge Exchange Spectra with L-shell Nickel Show Striking Differences from Models
G. L. Betancourt-Martinez, P. Beiersdorfer, G. V. Brown +7
We present the first high-resolution laboratory spectra of X-ray emission following L-shell charge exchange between nickel ions and neutral H2 and He. We employ the commonly used c…
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…
