Perseus cluster spectra
This X-ray spectrum of the Perseus Cluster was obtained with Ariel V. An emission feature is visible at about 7keV, due to Fe XXV and Fe XXVI. This feature provides strong evidence for the presence of hot plasma in the cluster. The overall spectrum is well described by bremsstrahlung emitted from an adiabatic hydrostatic atmosphere of hot gas in the gravitational potential well of the cluster.
