Hydrodynamic view in the NICA energy range

Results for penetrating probes treated within a hybrid hydro-kinetic model are projected onto the energy range covered by the NICA and FAIR projects. A new source of dileptons emitted from a mixed quark-hadron phase, quark-hadron bremsstrahlung, is proposed. An estimate for the $\pi\pi \to\sigma \to \gamma\gamma$ process in nuclear collisions is given.
