Proposal: 1. Measure transverse and elliptic flow for a wide range of energies (densities) at NICA and perform Danielewicz's flow data analysis ---> constrain stiffness of high density EoS2. Provide lower bound for onset of mixed phase ---> constrain QM onset in hybrid stars
- stiff EoS(at flow limit)
- low ncrit
(at NICA fixT)
- soft EoS (dashed line)
- high Mmax
(J1614-2230)
- low Monset
(all NS hybrid)
- excluded(J1614-2230)
