Findings

Transverse momentum spectra match experimental data.

Directed and elliptic flow patterns are characterized.

Interferometry radii provide insights into the fireball size.

Abstract

The expansion of the fireball created in Au-Au collisions at 200 GeV is described in (3+1)-dimensional viscous hydrodynamics with shear and bulk viscosities. We present results for the transverse momentum spectra, the directed and elliptic flow and the interferometry radii.
