This paper describes the first all-sky search for long-duration,
quasi-monochromatic gravitational-wave signals emitted by ultralight scalar
boson clouds around spinning black holes using data from the third observing
run of Advanced LIGO. We analyze the frequency range from 20~Hz to 610~Hz, over
a small frequency derivative range around zero, and use multiple frequency
resolutions to be robust towards possible signal frequency wanderings. Outliers
from this search are followed up using two different methods, one more suitable
for nearly monochromatic signals, and the other more robust towards frequency
fluctuations. We do not find any evidence for such signals and set upper limits
on the signal strain amplitude, the most stringent being $approx10^{-25}$ at
around 130~Hz. We interpret these upper limits as both an “exclusion region” in
the boson mass/black hole mass plane and the maximum detectable distance for a
given boson mass, based on an assumption of the age of the black hole/boson
cloud system.
