Intermediate-mass black holes (IMBHs) with masses between are crucial to our understanding of black hole seed formation and are the prime targets for the Laser Interferometer Space Antenna, yet black holes in this mass range have eluded detection by traditional optical spectroscopic surveys aimed at...
