Abstract:

Recent advances in observational cosmology have revealed that the large-scale distribution of galaxies in the universe has a honeycomb-like structure. However it is still a mystery how such diverse structures emerge out of primeval density fluctuations that grew over time due to the effects of gravity. An important role in the structure-formation process is played by the large-scale shocks that form as the primordial density fluctuations become non-linear and the accretion flows on collapsing structures become supersonic. In order to understand cosmic-rays acceleration greater than 1000 TeV and the structure formation in the early universe, we propose a 40 ksec observation of the proto-cluster filament ZwCl 2341.1+0000 (z = 0.27) with Suzaku.
