Azimuthal Asymmetries From Jets Quenched In Fluctuating Backgrounds
  High momentum jets and hadrons are important probes for the quark gluon plasma (QGP) formed in nuclear collisions at high energies. We investigate how fluctuations in the background density of the QGP and fluctuations in the spatial distribution of the hard process create azimuthal asymmetries of the high momentum hadron spectrum, described by the Fourier coefficients $v_n$, $n > 0$ . We estimate the coefficients up to $v_6$ in a simple energy loss model tuned to single inclusive hadron suppression.
