      abstract     = {Progress towards analysing transitions between steady
                      states demands improvements in time-resolved imaging, both
                      for fundamental research and for applications in information
                      technology. Transmission electron microscopy is a powerful
                      technique for investigating the atomic structure, chemical
                      composition and electromagnetic properties of materials with
                      high spatial resolution and precision. However, the
                      extraction of information about dynamic processes in the ps
                      time regime is often not possible without extensive
                      modification to the instrument while requiring careful
                      control of the operation conditions to not compromise the
                      beam quality. Here, we avoid these drawbacks by combining a
                      delay line detector with continuous illumination in a
                      transmission electron microscope. We visualize the gyration
                      of a magnetic vortex core in real space and show that
                      magnetization dynamics up to frequencies of 2.3 GHz can be
                      resolved with down to 122 ps temporal resolution by studying
                      the interaction of an electron beam with a microwave
                      magnetic field. In the future, this approach promises to
                      provide access to resonant dynamics by combining high
                      spatial resolution with sub-ns temporal resolution.},
