    The nuclear modification factor RAA for π0 production in Au+Au collisions at s=200A GeV is calculated and studied at high transverse momenta pT. The soft thermalized nuclear medium is described within the framework of relativistic ideal three-dimensional hydrodynamics. The energy loss of partonic jets is evaluated in the context of gluon bremsstrahlung in the thermalized partonic matter. We provide a systematic analysis of the azimuthal asymmetry of π0 suppression at high pT in central and noncentral collisions at mid and forward rapidity. The determination of RAA as a function of pT at different azimuthal angles and different rapidities makes for a stringent test of our theoretical understanding of jet energy loss over a variety of in-medium path lengths, temperatures, and initial partonic jet energies. This lays the groundwork for a tomography of the nuclear medium. © 2007 The American Physical Society.
