Chandra observation of the multiple merger cluster Abell 521
C. Ferrari, M. Arnaud, S. Ettori +2
We present the Chandra analysis of the galaxy cluster A521 (z=0.247). The high resolution of the Chandra observation has allowed us to refine the original merging scenario proposed…
The baryon fraction in hydrodynamical simulations of galaxy clusters
S. Ettori, K. Dolag, S. Borgani +1
We study the baryon mass fraction in a set of hydrodynamical simulations of galaxy clusters performed using the Tree+SPH code GADGET-2. We investigate the dependence of the baryon…
Brief history of the metal accumulation in the intracluster medium
S. Ettori
We use models of the rates of Type Ia supernovae (SNe Ia) and core-collapse supernovae, built in such a way that both are consistent with recent observational constraints at z<1.6…
Spectral properties and origin of the radio halo in A3562
S. Giacintucci, T. Venturi, G. Brunetti +6
We present a new detailed multiband study of the merging cluster A3562, in the core of the Shapley Concentration Supercluster. We analyzed new, low frequency radio data performed a…
HST/ACS weak lensing analysis of the galaxy cluster RDCS 1252.9-2927 at z=1.24
M. Lombardi, P. Rosati, J. P. Blakeslee +12
We present a weak lensing analysis of one of the most distant massive galaxy cluster known, RDCS 1252.9-2927 at z=1.24, using deep images from the Advanced Camera for Survey (ACS)…
