Abstract
We present the latest results on the collision energy dependence of $\eta/s$, obtained from a Bayesian model-to-data analysis of UrQMD + viscous hydrodynamics hybrid model to RHIC beam energy scan data for Au+Au collisions at 19.6, 39 and 62.4 GeV. Changes in the most likely value of $\eta/s$ over beam energy scan range suggest a dependence on baryon chemical potential $\mu_B$. However, we also find the uncertainties regarding the value of $\eta/s$ to be notable at $\sqrt{s_{NN}}=19.6$ GeV.
