In this video, we illustrate the thermal photons and charged hadrons emission in the transverse plane of a central Pb+Pb collision at sqrt{s} = 2.76 A TeV. The temperature evolution of the fireball is color coded. The purple contour indicates the chemical freeze-out surface at T_chem = 165 MeV and white contour represents for the kinetic freeze-out at T_dec = 120 MeV. Charged hadron (red points) productions are shown in the left panel. In the right panel, emitted thermal photons are shown as the green points.

Relativistic viscous hydrodynamic simulations at RHIC and LHC energies

This is a 2+1D hydrodynamical simulations for one particular heavy-ion collisions from the OSU group. The Quark-Gluon Plasma (QGP) is created shortly after the two heavy nuclei touched each other and the afterward evolution is hydrodynamical; with particle emission sampled using Cooper-Frye formula.

In the following video, you will watch the evolution of energy density and flow velocity in Au+Au collisions at 200A GeV at RHIC and Pb+Pb collisions at 2.76A TeV at LHC.
