X-ray spectral modeling and timing analysis of V1674 Her constrain its white dwarf mass to 1.09-1.12 solar masses, well below the near-Chandrasekhar value expected from its t2~1 day decline time.
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.
Discovery of Spearman correlation 0.8 between energy-dependent time lag and polarization degree in Swift J1727.8-1613, with theoretical arguments for additional mechanisms beyond inverse Comptonization.
An MCMC-based period search method recovers previously reported candidate periods in FRB 20201124A observations.
Candidate 0.22 Hz X-ray pulsations detected in NGC7456 ULX-1 with evidence of spin-up, pointing to an accreting neutron star.
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.
