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°.
First detection of mHz QPOs in 1A 0535+262 below 27 keV with frequencies evolving from 41 to 93 mHz, mostly hard lags, and double-peaked high-energy structure near outburst peak, interpreted as linked to soft-photon source and Comptonizing outflow evolution.
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.
