A phenomenological, thermodynamically consistent quasiparticle model of the quark-gluon plasma is constructed, taking into account information from lattice QCD simulations. Close to the phase transition, confinement is incorporated by a modification of the particle distribution function. The formalism is extended to systems with small quark chemical potential. For the description of ultra-relativistic heavy-ion collisions, a fireball is developed in accord with the quasiparticle model and a multitude of hadronic observables. Low mass dilepton radiation and J/psi suppression are calculated within a unified framework. Both times, the results are compared with experimental data from the CERN/SPS, and estimates for the RHIC collider are given. Finally, asymptotic freedom at high temperatures is derived using an external field method.
