      abstract     = {Second-order intensity interferometry was employed to study
                      the spatial and temporal properties of the European X-ray
                      Free-Electron Laser(EuXFEL). Measurements were performed at
                      the soft x-ray Self-Amplified Spontaneous Emission (SASE3)
                      undulator beamline at a photonenergy of 1.2 keV in the
                      Self-Amplified Spontaneous Emission (SASE) mode. Two
                      high-power regimes of the SASE3 undulator settings,
                      i.e.,linear and quadratic undulator tapering at saturation,
                      were studied in detail and compared with the linear gain
                      regime. The statistical analysisshowed an exceptionally high
                      degree of spatial coherence up to $90\%$ for the linear
                      undulator tapering. Analysis of the measured data in
                      spectraland spatial domains provided an average pulse
                      duration of about 10 fs in our measurements. The obtained
                      results will be valuable for theexperiments requiring and
                      exploiting short pulse duration and utilizing high coherence
