Central Massive Black Holes Are Not Ubiquitous in Local Low-mass Galaxies

The black hole occupation fraction ( f _occ ) defines the fraction of galaxies that harbor central massive black holes (MBHs), irrespective of their accretion activity level. While it is widely accepted that f _occ is nearly 100% in local massive galaxies with stellar masses M _⋆  ≳ 10 ^10 M _⊙ , it...
