Description

Measurements of the beam-energy dependence of anisotropic flow can provide important constraints for initial state models and for precision extraction of the chemical potential ($\mu_B$) and temperature ($T$) dependence of the QCD matter, specific shear viscosity $\eta/s$. It has been predicted that the $\mu_B$ and $T$ dependence on $\eta/s$ could be sensitive to the critical endpoint (CEP) in the QCD matter phase diagram\cite{Laszlo}. We will present and discuss recent RHIC measurements of the anisotropic flow coefficients $v_{n}$ ($1\leq n \leq 5$) as a function of harmonic number ($n$), transverse momentum ($p_T$), and centrality in Au$+$Au collisions across the full span of BES-I energies ($7.7 - 200$~GeV). The implication of these measurements for understanding the medium properties will be discussed.
