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 Element Abundances from the Solar Assembly for X-rays (SAX) on MESSENGER
B. R. Dennis, K. J. H. Phillips, R. A. Schwartz +3
X-ray spectra in the range ~keV have been analyzed for 526 large flares detected with the Solar Assembly for X-rays (SAX) on the Mercury {\em MESSENGER} spacecraft between…
RESIK Solar X-ray flare element abundances on a non-isothermal assumption
B. Sylwester, K. J. H. Phillips, J. Sylwester +1
Solar X-ray spectra from the RESIK crystal spectrometer on the {\em CORONAS-F} spacecraft (spectral range ~Å) are analyzed for thirty-three flares using a method to derive…
Trace element geochemistry of CR chondrite metal
Emmanuel Jacquet, Marine Paulhiac-Pison, Olivier Alard +2
We report trace element analyses by laser ablation inductively coupled plasma mass spectrometry of metal grains from 9 different CR chondrites, distinguishing grains from chondrule…
