ATLAS measurements of the azimuthal anisotropy in lead\u2013lead collisions at (Formula presented.) are shown using a dataset of approximately 7\ua0(Formula presented.) collected at the LHC in 2010. The measurements are performed for charged particles with transverse momenta (Formula presented.) and in the pseudorapidity range (Formula presented.) The anisotropy is characterized by the Fourier coefficients, (Formula presented.), of the charged-particle azimuthal angle distribution for (Formula presented.). The Fourier coefficients are evaluated using multi-particle cumulants calculated with the generating function method. Results on the transverse momentum, pseudorapidity and centrality dependence of the (Formula presented.) coefficients ar...
