Penetrating the Deep Cover of Compton Thick Active Galactic Nuclei
We analyze observations obtained with the Chandra X-ray Observatory of bright Compton thick active galactic nuclei (AGNs), those with column densities in excess of 1.5 × 10 cm along the lines of sight. We therefore view the powerful central engines only indirectly, even at X-ray energies. Using high spatial resolution and considering only galaxies that do not contain circumnuclear starbursts, w...
متن کاملActive Galactic Nuclei Emission-line Properties versus Eddington Ratio
We analyze UV spectra for a large sample of 578 Type 1 Active Galactic Nuclei and derive Eddington ratios, L/Ledd, from the bolometric luminosities and emission line widths for each object in the sample. The sample spans five orders of magnitude in supermassive black hole (SMBH) mass, seven orders of magnitude in luminosity, and a redshift range from 0 ≤ z ≤ 5. We include a sample of 26 lowreds...
متن کاملConstraints on radiatively inefficient accretion flow models from Eddington ratio distribution of active galactic nuclei
The radiative efficiencies of accretion flows become significantly lower than that of standard thin disks, if they are accreting at rates lower than a critical accretion rate ṁcrit. The transition of a standard thin disk to a radiatively inefficient accretion flow (RIAF) is expected to occur, while ṁ ∼ ṁcrit (ṁ = Ṁ/ṀEdd). We simulate the distributions of Eddington ratio λL B λ/LEdd for active g...
متن کاملConstraints on radiatively inefficient accretion history from Eddington ratio distribution of active galactic nuclei
The transition of a standard thin disk to a radiatively inefficient accretion flow (RIAF) is expected to occur, when ṁ ∼ ṁcrit (ṁ = Ṁ/ṀEdd). The radiative efficiencies of accretion flows accreting at rates lower than the critical accretion rate ṁcrit become significantly lower than that of standard thin disks. It is believed that the initial transition radius is small just after the accretion m...
متن کاملActive Galactic Nucleus Emission-line Properties versus the Eddington Ratio
We analyze UV spectra for a large sample of 578 type 1 active galactic nuclei and derive Eddington ratios, L=LEdd, from the bolometric luminosities and emission-line widths for each object in the sample. The sample spans 5 orders of magnitude in supermassive black hole (SMBH) mass, 7 orders of magnitude in luminosity, and a redshift range 0 z 5. We include a sample of 26 low-redshift narrow-lin...
