High-Resolution Solar X-ray Spectroscopy from Archived Solar Maximum Mission Data
Kenneth J. H. Phillips, Barbara Sylwester, Janusz Sylwester
Archived high-resolution X-ray spectra in the 13~Å to 22~Å range from the Flat Crystal Spectrometer (FCS), an instrument on the Solar Maximum Mission operating in the 1980s, are an…
Emission Measures Demystified
Brian R. Dennis, Kenneth J. H. Phillips
We review the terms, spectral radiance and spectral irradiance, and show how their precise definitions are crucial for interpreting observations made with different instruments cov…
Analysis of Quiescent Corona X-ray Spectra from SphinX during the 2009 Solar Minimum
B. Sylwester, J. Sylwester, M. Siarkowski +3
The SphinX X-ray spectrophotometer on the {\em CORONAS-PHOTON}\/ mission observed the 1~--~15\,keV X-ray spectrum of the spatially integrated solar corona during the deep minimum o…
The X-Ray Line Feature At 3.5 Kev In Galaxy Cluster Spectra
K. J. H. Phillips, B. Sylwester, J. Sylwester
Recent work by Bulbul et al. and Boyarsky et al. has suggested that a line feature at approx. 3.5 keV in the X-ray spectra of galaxy clusters and individual galaxies seen with XMM-…
Solar Flare Composition and Thermodynamics from RESIK X-ray Spectra
B. Sylwester, J. Sylwester, K. J. H. Phillips +2
Previous estimates of the solar flare abundances of Si, S, Cl, Ar, and K from the RESIK X-ray crystal spectrometer on board the CORONAS-F spacecraft were made on the assumption of…
