Intrinsic disc emission and the soft X-ray excess in active galactic nuclei
Abstract Narrow-line Seyfert 1 (NLS1) galaxies have low-mass black holes and mass
accretion rates close to (or exceeding) Eddington, so a standard blackbody accretion disc …

Massive thin accretion discs–I. Calculated spectra
We present detailed calculations of the structure and the spectrum of massive, geometrically
thin,'bare'accretion discs. The calculations are for an α-disc, with various assumptions about …

Self-shadowing effects of slim accretion disks in active galactic nuclei: the diverse appearance of the broad-line region
Supermassive black holes in active galactic nuclei (AGNs) undergo a wide range of
accretion rates, which lead to diversity of appearance. We consider the effects of anisotropic …

Survey of Bare Active Galactic Nuclei in the Local Universe (z< 0.2). I. On the Origin of Soft Excess
We analyze a sample of 21" bare" Seyfert 1 active galactic nuclei, a subclass of Seyfert 1
galaxies, with intrinsic absorption NH∼ 10 20 cm− 2, in the local Universe (z< 0.2) using …

RE J1034+ 396: the origin of the soft X-ray excess and quasi-periodic oscillation
M Middleton, C Done, M Ward… - Monthly Notices of …, 2009 - academic.oup.com
The X-ray quasi-periodic oscillation (QPO) seen in RE J1034+ 396 is so far unique amongst
active galactic nuclei (AGN). Here, we look at another unique feature of RE J1034+ 396 …

Continuum radiation from active galactic nuclei
JN Bregman - The Astronomy and Astrophysics Review, 1990 - Springer
Active galactic nuclei (AGN) can be divided into two broad classes, where the emitted
continuum power is dominated either by thermal emission (radio-quiet AGN), or by …
