Turbulent electron-ion coronae around accreting black holes self-regulate into a two-temperature state that generates nonthermal ions and X-ray spectra consistent with observations including an MeV tail.
A time-dependent model shows that star-disk collisions in TDE systems hosting EMRIs can eject 10^{-3} to 1 solar masses at 0.02-0.1c years after the initial flare, producing radio emission via interaction with circumnuclear material.
Six years of UV/X-ray monitoring of ESO 511-G030 reveals a >10x UV rise from the accretion disk, tight disk-corona coupling above ~1% Eddington, and breakdown below, indicating an accretion-state transition.
A criterion of |Δg| > 0.4 mag and |Δ(g-r)| > 0.2 mag detects photometric CL-AGN transitions in 9.6% of known hosts with 1.6% false positive rate from simulations.
Fast-spinning black holes can bend their disk's own thermal X-rays back onto the disk, and scattering can create a corona-free power-law tail with a distinctive polarization swing.
A new public relativistic transfer-function model reltrans for X-ray reverberation mapping that fits both spectra and lags to measure black-hole masses.
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.
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.
Simulations demonstrate that a retrograde IMBH with mass ratio ~0.67 to the disc mass fragments a stellar disc into inner, misaligned, and outer components within 10-20 Myr.
Simulations show magnetic field configurations set truncation radii and resonant cavities that produce QPO frequencies in thin disks matching black hole X-ray binary observations.
Compiled slab-geometry Seyfert coronae form a narrow constant-y≈0.77 locus, favouring dominant local coronal dissipation and reduced disc-corona feedback.
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.
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.
Mass-scaled DRW damping timescales in AGNs follow a linear relation with black hole mass (slope 0.35-0.50) for both jetted and non-jetted sources, supporting universal accretion physics.
Chandra HETG spectroscopy of BZ Cam diagnoses an ADAF-like advective hot flow with plasma densities of a few times 10^12-14 cm^-3, temperatures of 3-30 million K, and nonequilibrium ionization conditions.
Long-term X-ray monitoring indicates Swift J174610.4-290018 is a recurrent nova similar to RS Oph rather than an accretion-disk corona source.
Observational evidence links obscured super-Eddington accretion to slower precessing jets in stellar-mass compact object systems, contrasting with fixed fast jets in low-density environments.
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.
Radio precedes X-ray Compton luminosity by ~3 days in the rising hard state but lags by ~8 days in the decaying hard state of GX 339-4, with inner magnetic field strength estimated from accretion rate and truncation radius accounting for both.
AstroSat observation of MAXI J1535-571 reveals a tight correlation between QPO centroid frequency (1.7-3.0 Hz) and power-law index Gamma while flux increases linearly.
