RESUMO:

Data of the recent discovery of gravitational waves detected by Advanced Laser Interferometer
Gravitational Wave Observatory-LIGO were used in application of multifractal
analysis formalism. A time-series derived by strain measurement caused by gravitational
wave GW150914 was mounted. Detrended moving average method for multifractals,
named MFDMA, was used for analisys of such data. Shuffling and Surrogate procedures
was used for determinate sources of multifractality on the time series. Results indicate
two regimes of multifractality in time-series from GW150914. The instant that defines the
separation of these regimes may be interprated like the black holes merger time interval.
