Reaching the Peak of the quasar spectral energy distribution - II. Exploring the accretion disc, dusty torus and host galaxy
James S. Collinson, Martin J. Ward, Hermine Landt +3
We continue our study of the spectral energy distributions (SEDs) of 11 AGN at 1.5 < z < 2.2, with optical-NIR spectra, X-ray data and mid-IR photometry. In a previous paper we pre…
Determining the torus covering factors for a sample of type 1 AGN in the local Universe
Savithri H. Ezhikode, Poshak Gandhi, Chris Done +4
In the unified scheme of active galactic nuclei, a dusty torus absorbs and then reprocesses a fraction of the intrinsic luminosity which is emitted at longer wavelengths. Thus, sub…
On the black hole mass of the gamma-ray emitting narrow-line Seyfert 1 galaxy 1H 0323+342
H. Landt, M. J. Ward, M. Balokovic +6
Narrow-line Seyfert 1 galaxies have been identified by the Fermi Gamma-Ray Space Telescope as a rare class of gamma-ray emitting active galactic nuclei (AGN). The lowest-redshift c…
