      abstract     = {Waveguides offer a means to controllably couple atomic
                      ensembles to the electromagnetic field therein. Here, we
                      demonstrate x-ray propagation in planar thin-film waveguides
                      coupled to Mössbauer nuclei under collective resonant
                      excitation by short pulses of synchrotron radiation. We
                      record x-ray photons that have been emitted into resonant
                      modes of the waveguide. Depending on the geometry and mode
                      of excitation, two fundamentally different signatures of the
                      collective emission are observed, for which we present a
                      unifying theoretical model. Our results form a new platform
                      for waveguide quantum electrodynamics in the hard x-ray
                      regime with the potential to provide a coherent narrow band
                      source of x-rays on the nanometer scale.},
