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.
Candidate mHz QPOs detected in GX 3+1 at 7-15 mHz with 0.51-1.41% rms, one surviving global significance, occurring at higher luminosities than in other NS LMXBs.
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.
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.
