Multi-epoch observations of 1A 1246-588 show blackbody temperature rising from 0.28 to 0.39 keV with emitting radius 6.9-13.8 km and Comptonization photon index varying 1.8-2.3, consistent with atoll-state changes from accretion power redistribution.

Multi-wavelength data classify the Einstein Probe transient EP250916a as a faint hard-state black hole X-ray binary candidate.
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.
The 2026 outburst of 1A 1118-61 is brighter and spectrally harder than in 2009, with constant cyclotron line energy across large luminosity changes and QPO frequency suggesting magnetospheric instabilities.
NuSTAR and NICER data on SAX J1808.4-3658 show the accretion disk truncating to ~23 R_g in 2025 with magnetospheric radius exceeding co-rotation radius, indicating a possible transition to the propeller regime while accretion continues as evidenced by a Type-I burst.
Statistical correlation analysis links the KM3-230213A neutrino to multiple GRBs within angular errors and computes LV scales incorporating redshift and energy uncertainties.
