The discovery of the almost perfect fluid-like nature of the strongly interacting quark–gluon plasma was one of the most important discoveries of heavy-ion physics in recent decades. The experimental results are well-described by hydrodynamical models. Most of these models are numerical simulations, however the analytic solutions are also important in understanding the time evolution of the quark–gluon plasma created in the heavy-ion collisions. Here, we present a perturbative, accelerating solution on top of a known solution, the relativistic Hubble flow. We describe the perturbative class of solutions and calculate a few observables for a selected solution.
