Academic mobility plays a predominant role in the context of increasing the internationalization of science and research production, thus creating a global market of qualified professionals (Franzoni et al., 2015 , Schiller and Cordes, 2016 , Netz and Jaksztat, 2017) . Germany has launched a series of programs that have the aim to attract researchers with high citation performance and link German-affiliated scientists abroad with each other (Schiller and Cordes, 2016). Thus, mapping the German

... cademic in-and out-flow patterns across countries and disciplines can help clarify the position and attraction of Germany in the global science system. Taking all fields of scholarship, this analysis speaks directly to policy development. Using large-scale bibliometric data from over 8 million Scopus publications during the period 1996-2020, we analyze and visualize the international migration to and from Germany among published researchers by taking into account their citation information and semantically identified disciplines. This reveals the spatial hotspots of migration and in-and out-flows for all fields of scholarship.
