Coronal Heating and Emission Mechanisms in Agn

Popular models for the formation of X-ray spectra in AGN assume that a large fraction of the disk’s angular momentum dissipation takes place in a hot corona that carries a small amount of the accreting mass. Here I discuss the formation of a magnetically–structured accretion disk corona, generated by buoyancy instability in the disk and the heating of localized flare regions up to the canonical...

Agn Models: High-energy Emission

Astrophysical models for the high-energy emission of blazars are reviewed. Blazars ejecting relativistic radio jets at small angles to the line-of-sight are the only type of active galactic nuclei (AGN) discovered above 100 MeV. The γ-rays apparently originate in the jets which explains the absence of γ-ray pair creation attenuation. The bulk Lorentz factor of the radio jets is much smaller tha...

Anisotropic [OIII] emission in radio loud AGN

We present the results of spectropolarimetry of a sample of 7 powerful radio galaxies and 2 quasars with 0.07 < z < 0.35 obtained to detect possible anisotropies in the [OIII] line emission, which could explain the higher [OIII] luminosity of quasars than that of radio galaxies within the framework of the Unified Model of radio-loud AGN. We detect polarized [OIII] in 4 radio galaxies, consisten...

Radio Emission from AGN detected by the VLA FIRST Survey

Using the most recent (April 2003) version of the VLA FIRST survey radio catalog, we have searched for radio emission from > 2800 AGN taken from the most recent (2001) version of the Veron-Cetty and Veron AGN catalog. These AGN lie in the ∼9033 square degrees of sky already covered by the VLA FIRST survey. Our work has resulted in positive detection of radio emission from 775 AGN of which 214 a...
