| Abstract: |
Entropy profiles of galaxy clusters are systematically different when
simulated with SPH versus Eulerian mesh codes. This systematic difference has
persisted until now, casting doubt hydrodynamical schemes can follow complex
hydrodynamical flows in full cosmological settings reliably. We present results
from a novel set of simulations performed both with a Lagrangian SPH code GADGET and with a recently developed moving mesh code AREPO. This suite of simulations sheds light on the physical and numerical
mechanisms which are responsible for the systematic discrepancies
in the entropy profiles. |
