    "abstract": "Recent progress in the study of the photon emission from highly-charged heavy\nions is reviewed. These investigations show that high-$Z$ ions provide a unique\ntool for improving the understanding of the electron-electron and\nelectron-photon interaction in the presence of strong fields. Apart from the\nbound-state transitions, which are accurately described in the framework of\nQuantum Electrodynamics, much information has been obtained also from the\nradiative capture of (quasi-) free electrons by high-$Z$ ions. Many features in\nthe observed spectra hereby confirm the inherently relativistic behavior of\neven the simplest compound quantum systems in Nature.",
