Abstract :
We present results from a new 120 ks XMM-Newton observation of the cluster of galaxies Sérsic 159-03. In this paper, we focus on the high-resolution X-ray spectra obtained with the Reflection Grating Spectrometer (RGS). The spectra allow us to constrain the temperature structure in the core of the cluster and determine the emission measure distribution as a function of temperature. We also fit the line widths of mainly oxygen and iron lines.
