    "abstract": "We use a hydrodynamic model to study the space-time evolution transverse to\nthe beam direction in ultrarelativistic heavy-ion collisions with nonzero\nimpact parameters. We focus on the influence of early pressure on the\ndevelopment of radial and elliptic flow. We show that at high energies elliptic\nflow is generated only during the initial stages of the expansion while radial\nflow continues to grow until freeze-out. Quantitative comparisons with SPS data\nfrom semiperipheral Pb+Pb collisions suggest the applicability of\nhydrodynamical concepts already $\\approx$ 1 fm/c after impact.",
