Merging history of three bimodal clusters
S. Maurogordato, J. -L. Sauvageot, H. Bourdin +5
We present a combined X-ray and optical analysis of three bimodal galaxy clusters selected as merging candidates at z ~ 0.1. These targets are part of MUSIC (MUlti--Wavelength Samp…
A2163: Merger events in the hottest Abell galaxy cluster I. Dynamical analysis from optical data
S. Maurogordato, A. Cappi, C. Ferrari +7
We present a detailed optical analysis of the galaxy cluster A2163 based on new multicolor wide field imaging and medium-to-high resolution (R~2000) spectroscopy. While X-ray obser…
