      abstract     = {The double differential cross-section for $Z$ bosons
                      decaying in the electron channel was measured as a function
                      of the di-electron invariant mass and rapidity. For this
                      measurement, the data collected at the ATLAS detector at the
                      LHC during 2011 at a center-of-mass energy of $\sqrt{s} = 7$
                      TeV was used.The analysis is focused on the central-forward
                      $Z$ bosons, i.e. the bosons that decay into two electrons,
                      one of which is reconstructed in the central region of the
                      detector ($|\eta| < 2.5$) and the other in the forward
                      region of the detector ($|\eta| > 2.5$). Several sources of
                      the systematic uncertainties were taken into account,
                      including the electron reconstruction and identification
                      efficiencies, pileup effects, PDF sets for the initial
                      protons, and differences between various Monte Carlo
                      simulations. The main sources of uncertainties were found to
                      be the efficiency scales of the forward electron
                      identification and the forward electron energy resolution.
                      The results of the analysis are in agreement with
                      measurements in other decay channels of the $Z$ boson and
                      with theoretical predictions.The fast simulation method
                      called Frozen Showers was developed to speed up the
                      simulation of Monte Carlo data samples. This method
                      increases the simulation speed by $\sim$25\% while
                      introducing additional errors of less than 1\% in the energy
                      scale and resolution of the reconstructed particles. The
                      method was used to speed up the production of all Monte
                      Carlo samples used in this analysis.},
