  The physics of the QCD phase diagram is discussed in view from heavy-ion
collisions, compact astrophysical phenomena, lattice QCD and chiral effective
models. We find that (T,mu_B) region probed in heavy-ion collisions and the
black hole formation processes covers most of the critical point locations
predicted in recent lattice QCD Monte-Carlo simulations and chiral effective
models of QCD. We also discuss the consistency of the statistical model results
and dynamical model description.
