Infrared Emission from AGN
Infrared observations of complete samples of active galactic nuclei (AGN) have shown that a substantial fraction of their bolometric luminosity is emitted at wavelengths ∼8–1000μm. In radio-loud and Blazar-like objects much of this emission appears to be direct nonthermal synchrotron radiation. However, in the much larger numbers of radio-quiet AGN it is now clear that thermal dust emission is ...
متن کاملSimulated Molecular Gas Emission in Galaxy Mergers with Embedded AGN
We investigate the effect of embedded active galactic nuclei (AGN) in galaxy mergers on the CO molecular line emission by combining non-local thermodynamic equilibrium (LTE) radiative transfer calculations with hydrodynamic simulations. We find that AGN feedback energy in gas rich galaxy mergers can contribute to large molecular outflows which may be detectable via velocityintegrated emission c...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولEffects of Metallicity and Agn Activity on the Mid-infrared Dust Emission of Galaxies
Using a sample of the Spitzer SWIRE-field galaxies whose optical spectra are taken from the Data Release 4 of the Sloan Digital Sky Survey, we study possible correlations between the Mid-InfraRed (MIR) dust emission from these galaxies and both their metallicities and AGN activities. We find that both metallicity and AGN activity are well correlated with the following ratios: PAH(Polycyclic Aro...
متن کاملInfrared emission from the dusty veil around AGN
We discuss consequences of the concept of a clumpy and dusty torus around AGN. Cloud-cloud collisions lead to an effective viscosity and a geometrically thick accretion disk, which has the required properties of a torus. A quantitative comparison of radiative transfer calculations for dust re-emission from the torus with NIR images, longbaseline visibilities and spectral energy distributions fo...
