[13.14] A study of the radial metallicity and temperature distributions for a sample of galaxy clusters observed with BeppoSAX

S. De Grandi (Osservatorio Astronomico di Brera)

We present, for the first time, a comprehensive analysis of nearby galaxy clusters observed with BeppoSAX. The better spatial resolution of the BeppoSAX data when compared to the ASCA data allow us to improve substantially on similar studies conducted with ASCA. Our main results can be summarized as follows. Merging clusters can exhibit very different temperature profiles, on the contrary cooling-flow clusters show evidence of a universal temperature profile. Merging clusters have flat Fe profiles while cooling-flow clusters have very strong Fe gradients.
