Abstract

A novel approach for source detection via structural deviations from the typical features of a random background counts map is presented. Minkowski functionals, powerful tools from integral geometry, quantify the shape of level sets of a counts map. Compared to standard techniques, which use the total number of counts only, additional morphometric information is incorporated without the need for any prior knowledge about the source. Minkowski sky maps quantify local structural deviations; they localize and visualize potential sources.
