XRISM multi-epoch spectra of NGC 4151 yield a 3.5-day lag in the narrow Fe Kα line flux, consistent with a broad-line-region origin and giving M_BH/f_X ≈ 2×10^7 solar masses.

XRISM spectroscopy of NGC 4388 shows the Fe Kα line arising from the torus, inner torus edge, and BLR at distinct radii, with absorption revealing a gravitationally bound failed wind.
Disk reflection from a compact lamp-post corona explains the X-ray polarization and spectra of NGC 4151.
Calibrated AGN disk-wind models contribute ≲5% to the CGB above 10 GeV and ≲10% to the CNB at 100 TeV and are unlikely to dominate either background.
