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…
