We are currently in an exciting era where large populations of 1e4-1e6 Msun intermediate black holes are being recovered in the nuclei of low-mass galaxies which are informing our understanding on the growth of supermassive black holes. However we still lack observational constraints on possible nuclear black holes in the virgul1000 Msun range save for a handful of candidates. We identified a 3000-4000 Msun intermediate mass black hole candidate from a Chandra observation of a late-type spiral galaxy on account of a soft and luminous (near-Eddington) X-ray spectrum. Here we propose an EPIC XMM-Newton spectrum (with nearly 20 times more counts) to confirm/refute our current intermediate mass black hole interpretation. [truncated!
