AGN cool feedback and analogy with X-ray binaries: from radiation pressure to cosmic ray driven outflows
W. Ishibashi, A. C. Fabian
Cool outflows are now commonly observed in galaxies, but their physical origin and driving mechanism remain unclear. Active galactic nucleus (AGN) feedback can potentially accelera…

The physical origin of the X-ray power spectral density break timescale in accreting black holes
W. Ishibashi, T. J. -L. Courvoisier
X-ray variability of active galactic nuclei (AGN) and black hole binaries can be analysed by means of the power spectral density (PSD). The break observed in the power spectrum def…

Synchrotron radio emission in radio-quiet AGNs
W. Ishibashi, T. J. -L. Courvoisier
The basic mechanism responsible for radio emission in radio-loud active galactic nuclei (AGNs) is assumed to be synchrotron radiation. We suggest here that radio emission in radio-…
