A new public relativistic transfer-function model reltrans for X-ray reverberation mapping that fits both spectra and lags to measure black-hole masses.
HE 1237-2252 exhibits a changing-look event driven by intrinsic accretion-rate variations, revealing a two-component broad-line region consisting of virialized gas at ~27 light-days and disk emission at larger radii.
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.
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.
