Azimuthal correlations and collective effects in a heavy-ion collisions at the LHC energies

Recent highlights from the anisotropic flow and the azimuthal correlation measurements in a heavy-ion collisions at the LHC are presented. Various flow harmonics measured for the charged and identified particles versus transverse momentum, pseudo-rapidity, and the collision centrality are reported. New experimental probes of the local parity violation at the LHC energies using the charge dependent azimuthal correlations are also discussed.
