The Intermediate-mass Black Hole Reverberation Mapping Project: Stable Optical Continuum Lags of an Intermediate-mass Black Hole in the Dwarf Galaxy NGC 4395 over Years

NGC 4395 is a nearby dwarf spiral galaxy hosting an active galactic nucleus (AGN) powered by an intermediate-mass black hole (IMBH; M _BH  ∼ 10 ^4−5 M _⊙ ). Recent optical continuum reverberation mapping studies have suggested potential lag variations between different epochs, offering important clu...
