The X-ray disc/wind degeneracy in AGN

M. L. Parker et al.

Summary: The relativistic Fe K emission lines from accretion discs and disc winds provide crucial information about black holes and their accretion and feedback mechanisms. However, it is difficult to distinguish between these two processes based on spectral analysis. It is likely that both processes contribute to the net line profile in many cases, and their relative contributions cannot be determined solely by Fe K spectroscopy.

The Inner Accretion Flow in the Resurgent Seyfert-1.2 AGN Mrk 817

J. M. Miller et al.

Summary: Research shows that accretion disks and coronae around massive black holes may decouple in the short term. Observations of Mrk 817 reveal that the X-ray and UV spectra are decoupled on timescales of weeks and months, potentially requiring the presence of a mechanical beaming of the innermost accretion flow or an absorber to explain.
