Red quasars are intrinsically X-ray weak with low alpha_OX values, tracing a distinct evolutionary stage of suppressed black hole accretion relative to stellar mass growth.
Kerr-MOG accretion disk spectra are softer than Kerr at fixed spin due to outward ISCO shift from the fifth-force parameter α, with an observational upper limit α < 0.044 from LMC X-1 data.
Fe Kα lines from accreting black holes are produced mostly outside 10 gravitational radii due to radial ionization gradients, allowing broad profiles without high spin.
A new main-sequence evolution framework implemented in COMPAS yields more massive helium cores, more compact stripped-star radii, and systematically higher black-hole masses than standard prescriptions.
No orbital polarization modulation at P_orb or P_orb/2 is detected in combined IXPE data for Cygnus X-1, with 99% upper limits of 0.54-2.13% on P_orb/2 amplitude across 2-8 keV bands, consistent with sensitivity limits.
GRMHD simulations identify magnetic flux through the black hole horizon as the key variable setting jet efficiency and radiative output across MAD, INT, and SANE states, with mappings to temporal classes in GRS 1915+105 and other sources.
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.
A review of extreme gamma-ray transients defined as catastrophic events or extreme particle acceleration regimes, covering diagnostics, instruments, and source classes.
