Abstract NGC 4945 contains a well-known heavily obscured active galactic nucleus (AGN) at its core, with prior reports of strong nuclear and off-nuclear neutral Fe K α emission due to the AGN activity. We report discovery very extended XMM-Newton EPIC pn in ∼5 kpc by ∼10 region that is misaligned plane inclined optical disk ∼60° projection. After careful consideration crowded center galaxy numerous unresolved hard X-ray sources present, we estimate ∼15% on kiloparsec-sized scales. The...
NGC 4945 contains a well-known heavily obscured active galactic nucleus (AGN) at its core, with prior reports of strong nuclear and off-nuclear neutral Fe K$\alpha$ emission due to the AGN activity. We report discovery very extended XMM-Newton EPIC pn in $\sim5$ kpc by $\sim10$ region that is misaligned plane inclined optical galaxy disk $\sim60$ degrees projection. After careful consideration crowded center numerous unresolved hard X-ray sources present, we estimate $\sim15$% on kpc-sized...
