Scientific paper

Citations between papers form a directed, modular network. We have used information theory to partition such a network into modules, by minimizing its description length (Henneken et al. 2008, Rosvall et al. 2007). Using citations between astronomy articles, these modules help to define a thematic map of the astronomy literature. We present a tool to interactively explore this landscape. It allows the user to see the connection between the various thematic modules and to explore the contents of individual modules. This tool adds valuable citation-oriented exploration to the existing list-oriented exploration of the astronomy literature.
