Type-C QPOs in Swift J1727.8-1613 exhibit energy-dependent rms-frequency relations with a common break at 4 Hz, indicating a change in accretion geometry.
Comprehensive analysis of AstroSat data shows a sign change in QPO time lags at ~2 Hz for high-inclination sources, consistent with a transition from elongated jet-like to compact corona.
