Type-C QPO amplitudes correlate linearly with jet inclination up to 8 Hz in BH LMXBs, lower on decay than rise, reproducible by precessing hot flow if misalignment ≥10-15°.
Detection of an imaginary QPO in AT2019wey whose frequency drops from ~5 Hz to ~1 Hz with rising phase lags as the source transitions through HIMS and LHS, showing U-shaped phase-lag spectrum in HIMS.
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.
A recurring 0.03 Hz radio QPO was detected in the 2025 flare of GRS 1915+105 at >5.9 sigma in one epoch, identical across S- and X-bands and prior years, indicating an intrinsic accretion-jet timescale.
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.
