Observations of nearby galaxies and their components allow us to study the physics of stellar endpoints, their impact on the interstellar medium, all the way to the formation of the next generationsof stars and planets, and thus the evolution of galaxies in the nearby Universe. Today's space and ground-based telescopes allow high-resolution, high-sensitivity observations and provide us with a wealth of observational data most of which are available in public archives. Moreover, new observatories both in space and on Earth are planned for the next years and decades and will assure new groundbreaking discoveries. Black holes, neutron stars, or supernova remnants produced at the final stages of stellar evolution, are mainly high-energy sources, whereas the colder phases of the interstellar medium together with star-forming regions are objects that are observable at lower energies. While there are big efforts to make advance in the respective fields of Astrophysical research, there has been no significant overlap between the different science communities so far. In the next years, exactly these two fields will become more relevant with the preparation and the launch of the large next-generation observatories like the James Webb Space Telescope or the Athena X-rayObservatory. In th proposed project, these fields of research will be combined in a comprehensive multi-wavelength study with the main aim to understand the galactic matter cycle and the origin of elements,and hence the evolution of galaxies in today's Universe.
