AbstractRecent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repetitive events around SMBHs, including the recently discovered quasi-periodic eruptions1,2,3,4,5, are garnering further interest in stellar-mass companions around SMBHs and the progenitors to millihertz-frequency gravitational-wave events.

Black holes are usually the corpses of long-dead stars—ones that lived and died in a blinding flash called a supernova. This cataclysmic explosion crushes the core to densities billions of times greater than any substance found on Earth.
