Solar wind charge exchange: an astrophysical nuisance

KD Kuntz - The Astronomy and Astrophysics Review, 2019 - Springer
Solar wind charge-exchange (SWCX) emission is present in every X-ray observation of an
astrophysical object. The emission is problematic when one cannot remove the foreground …

Flux Contribution and Geometry of Charge Exchange Emission in the Starburst Galaxy M82

H Okon, RK Smith, A Picquenot… - The Astrophysical …, 2024 - iopscience.iop.org
Recent X-ray studies of starburst galaxies have found that charge exchange (CX) commonly
occurs between outflowing hot plasma and cold gas, possibly from swept-up clouds …

Geocoronal Solar Wind Charge Exchange Process Associated With the 2006‐December‐13 Coronal Mass Ejection Event

Y Zhou, NY Yamasaki, S Toriumi… - Journal of Geophysical …, 2023 - Wiley Online Library
We report the discovery of a geocoronal solar wind charge exchange (SWCX) event
corresponding to the well‐known 2006 December 13th coronal mass ejection (CME) event …

X-ray spectroscopy of galaxy clusters: beyond the CIE modeling

L Gu, I Zhuravleva, E Churazov, F Paerels… - Space Science …, 2018 - Springer
X-ray spectra of galaxy clusters are dominated by the thermal emission from the hot
intracluster medium. In some cases, besides the thermal component, spectral models …

Charge-exchange soft X-ray emission of highly charged ions with inclusion of multiple-electron capture

GY Liang, XL Zhu, HG Wei, DW Yuan… - Monthly Notices of …, 2021 - academic.oup.com
