The origin of optical emission from super-Eddington accreting Active Galactic Nuclei: The case of Ton S 180.

KAWAGUCHI T., PIERENS A. and HURE J.-M.

Abstract (from CDS):

Self-gravitating accretion discs have only been studied in a few nearby objects using maser spots at the parsec-scale. We find a new spectral window for observing the self-gravitating accretion disc in super-Eddington accreting Active Galactic Nuclei (AGNs). This window is determined by calculating the outermost radius (rsg) of a non self-gravitating disc and the corresponding emission wavelength (λsg) as a function of various disc parameters. We find that λsg reaches ∼4000Å for α=0.1, when {dot}(M)>70(MBH/107M)–1LEdd/c2 (where α, {dot}(M), MBH and LEdd are, respectively, the viscosity parameter, gas accretion rate onto the central black hole (BH), the BH mass and the Eddington luminosity). Moreover, λsg is as small as ∼ 1500Å for α=0.001, which is the smallest α case in this study. Therefore, the window for observing the self-gravitating part of an AGN accretion disc is from ∼ 2µm to λsg. Incidentally, rsg can be less than the photon trapping radius for {dot}(M)>103.3LEdd/c2. Namely, a self-gravitating, optically-thick, advection-dominated accretion disc is expected to appear in the extremely high accretion rate regime. Next, we demonstrate that the Mid-Infrared to X-ray spectrum of a bright, well-studied Narrow-Line Seyfert 1 galaxy, Ton S 180, is indeed well fitted by the spectrum arising from the following three components: an inner slim disc (with a corona), an outer, self-gravitating non-Keplerian disc and a dusty torus. The total mass, BH mass plus the entire disc mass, is found to be about (1.4-8.0) MBH. If the surface density varies with radius r in proportion to r–0.6, the total mass is consistent with the central mass estimated by Hβ and [O III] widths.

within radius arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
