Abstract : Time lags of Galactic black hole candidates and AGNs are becoming more and more important in the last few years. Some of the intriguing features of lag properties are discovered in recent years. However, the nature of lag variations remain unknown mostly because of the non-linear physical mechanisms that are originating the lag of the photons which are coming from the accretion disks. The hard lag contribution is found to be originated from the inverse Comptonization and disk reflection mechanism. But, the exact reason for soft lags are yet to be unveiled. We discover a perfect correlation between the radio flux of various candidates where soft lags are found. The correlation strongly suggests that in the event of massive radio flares, soft lags are produced for both black hole candidates and AGNs.
