Nuclear modification factors, directed and elliptic flow of electrons from open heavy flavor decays in Au+Au collisions from STAR

We present the analyses of single electrons from semileptonic bottom and charm hadron decays at mid-rapidity in $\sqrt{s_{NN}}$ = 200 and 54.4 GeV Au+Au collisions (talk in Heavy-Flavor session III). The data at $\sqrt{s_{NN}}$ = 200 GeV incorporate information from the Heavy Flavor Tracker which enables the topological separation of electrons originating from bottom and charm hadron decays. We report the first STAR measurements at $\sqrt{s_{NN}}$ = 200 GeV of $v_2$ for bottom decay electrons as a function of $p_T$ and $v_1$ for charm decay electrons as a function of electron rapidity. Additionally, we present the improved measurements of heavy-flavor decay electron $R_{AA}$ and a new measurement of the ratio of $R_{CP}$ between bottom and charm decay electrons. Finally, we also report the measurement of non-photonic electron $v_2$ in $\sqrt{s_{NN}}$ = 54.4 GeV data collected during the 2017 RHIC run.
