A newborn spider system at the core of a radio shell: Evidence of a low-energy supernova

In a search for radio nebulae with a low surface brightness within the ASKAP-EMU survey, we discovered a faint radio shell, G289.6+5.8, and its central point radio source at the position of the soft γ-ray source IGR J11187-5438. The central radio source is spatially coincident with a previously know...
