Extreme Slim Accretion Disks and Narrow Line Seyfert 1 Galaxies: the Nature of the soft X-ray Hump

Jian-Min Wang, Hagai Netzer

We present a detailed model of an extreme slim disk (ESD) with a hot corona around a massive black hole with dimensionless accretion rate $\dotm$ in the range $2.5\ll \dotm\leq 100…
