Quasi-periodic flux variations in pulsar 1A 0535+262 are accompanied by synchronized cyclotron line energy oscillations, providing evidence for rapid geometric reconfiguration of the accretion column in the radiation-pressure-dominated regime.

A soft-spectrum PULX candidate is reported in Cen A but XMM-SAS randomisation during data reduction renders the marginal 1.27 Hz pulsation detection unreliable across repeated reductions.
First IXPE polarization measurement of GX 340+0 in normal branch yields PD 1.22±0.25% and PA 38±6°, consistent with origin in blackbody or Comptonized emission, with radio flux lower than in horizontal branch.
Candidate 1.97 keV absorption line in HLX 2SXPS J111416.1+481833 interpreted as proton CRSF implying B ~ 4e14 G for a neutron star accretor.
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.
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.
EP J174942.2-384834 is classified as a very faint X-ray transient black hole candidate based on its hard X-ray spectra, optical/UV brightening correlated with X-rays, and lack of radio emission.
New XRISM observations confirm a highly broadened, pulsating Fe K line from the accretion column of Hercules X-1 that varies with pulse phase and evolves with the 35-day precession cycle.
New EP-FXT data on the 2024 outburst of magnetar 1E 1841-045 shows energy-dependent multi-peaked pulses, spectral hardening, BB temperature-pulse intensity correlations, and effective separation from supernova remnant emission.
An MCMC-based period search method recovers previously reported candidate periods in FRB 20201124A observations.
Observations show a long thermonuclear burst in MAXI J0911--655 followed by a flare interpreted as burst-driven thermal-viscous disk instability enhancing accretion.
EP260321a is identified as the faintest shock breakout X-ray transient associated with broad-lined Ic supernova SN 2026gzf, interpreted as originating from a mildly relativistic weak outflow choked inside the progenitor star.
Multi-wavelength data from SDSS J1430+2303 are interpreted as evidence that radiation pressure instabilities drive a shrinking unstable accretion-disk zone, based on timing analysis, weak soft excess, and SED-derived black-hole parameters.
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.
Black hole spin constraints for Cyg X-1 from XRISM Resolve data are strongly model-dependent, ranging from a*~0.99 with relxill to a*~0 with relxillCp or reflkerrD.
Wideband observations show M28A giant pulses differ from FRB 20200120E bursts in duration, luminosity, timing statistics, and spectral structure, yielding no strong evidence for a direct link.
