Cluster iron lines and the X-ray spectrum of SC 0627-544.
Abstract
Further observations with the MSSL proportional counter spectrometer on the Ariel V satellite have led to the detection (at a confidence level of at least 99 per cent) of a highly ionized iron emission feature in the spectrum of the southern cluster SC 0627-544. The data obtained are compared with previous observations of this source made by the Goddard Space Flight Center's instrument on OSO-8. Iron emission feature detections with greater than 99 per cent confidence levels have now been made for five clusters of galaxies. A value of cluster iron abundance is deduced from these data.
