Solar Wind Charge Exchange From Dennerl 2010

Solar Wind Charge Exchange Charge exchange (CX) nature of comet X-ray emission is confirmed, spectroscopically and temporally. CX has a cross-section of ~ cm -2 P CX /P th propto 1/n e 2 on scales of mean free path Peter Beiersdorfer CX is also expected at the heliosphere

Much of the diffuse soft X-ray background may arise from the CX! ROSAT all-sky survey in the ¾-keV band X-ray binary AGN Futamoto et al. 2004, Wang et al. 05, Yao & Wang 05/06, Yao et al. 06/07/08 4U

XMM-Newton RGS spectrum of the nuclear starburst region of M51 Charge exchange may be responsible for much of diffuse soft X-ray emission in both normal and starburst galaxies.

Similar CX signatures are also observed in starburst galaxies Soft X-ray arises primarily from the interplay between a superwind and entrained cool gas clouds. Composite of optical (HST), infrared (Spitzer), and X-ray (Chandra) images Li, Mao, Wang 2011

Summary X-ray spectroscopy is the future of the X- ray astronomy  X-ray astrophysics, providing key diagnostics of plasma in the Universe. Much of the diffuse X-ray emission from galaxies may arise from the charge exchange. A lot can already be done to understand the process, which traces the galactic feedback and the presence of cool gas, especially in low density environments.
