  The suppression of high transverse momentum (P_T) jets and hadrons in
ultrarelativistic heavy-ion collisions with respect to a p-p baseline in terms
of the nuclear suppression factor R_AA is one of the key observables to gauge
the density of a hot and dense QCD medium. However, the suppression measured by
R_AA is not a straightforward measure of the medium properties, the value of
the observable also depends on the ratio of quark to gluon jets and on the
slope of the hard parton spectrum, which explains why R_AA is found to be
fairly similar at RHIC and LHC despite the very different dynamics. Measuring
high P_T jets and hadrons at forward rapidity offers the same possibility of
varying medium density, parton mixture and spectral slope without the need to
compare across different sqrt(s) and experiments. In this work, the well-tested
jet quenching Monte-Carlo (MC) framework YaJEM is utilized to compute the
rapidity dependence of R_AA for three test cases.
