Dynamical modeling of relativistic heavy ion collisions

It is quite important to describe space-time evolution of matter created in relativistic heavy ion collisions toward understanding bulk and transport properties of the quark gluon plasma (QGP). We discuss current status of dynamical modeling in relativistic heavy ion collisions based on fully three dimensional ideal hydrodynamics. We obtain local temperature of the QGP by numerically solving hydrodynamic equations. We also utilize hydrodynamic solutions to estimate other observables such as high pT spectra for hadrons, J/ψ suppression, string formation between a jet parton and a fluid parton and electro-magnetic spectra.
