Evidence for an intermediate mass black hole and a multi-zone warm absorber in NGC 4395
D. C. Shih, K. Iwasawa, A. C. Fabian
We report on the results of an analysis in the X-ray band of a recent long ASCA observation of NGC 4395, the most variable low-luminosity AGN known. A relativistically-broadened ir…

Reflection Spectra from Photoionized Accretion Discs
D. R. Ballantyne, R. R. Ross, A. C. Fabian
We review recent progress on the modeling and use of reflection spectra from irradiated and ionized accretion discs. On the computational side, calculations of reflection spectra f…

Magnetic flares and outflows from structured accretion disc coronae
A. Merloni, A. C. Fabian
We present a model for magnetic structured coronae above accretion discs. On the shortest timescales, spatially and temporally correlated coronal flares can explain X-ray temporal…
