AGN and Starburst Galaxies Seen through Radio Surveys

چکیده
The emergence of a new population of radio galaxies at mJy and sub-mJy levels is responsible for the change in the slope of the radio source counts. This population seems to include both star forming galaxies and classical (AGN-powered) radio sources, but the relative importance of the two classes is still debated. We present results from the ATESP radio survey and its optical follow-up and show that the fraction of starburst galaxies changes from ∼ 15% at fluxes ≥ 1 mJy to ≥ 50% at lower fluxes.

AGN Zoo and Classications of Active Galaxies
We review the variety of Active Galactic Nuclei (AGN) classes (so-calledAGN zoo") and classification schemes of galaxies by activity types based on their optical emission-line spectrum, as well as other parameters and other than optical wave-length ranges. A historical overview of discoveries of various types of active galaxies is given, including Seyfert galaxies, radio galaxies, QSOs, BL Lace...
متن کاملObscuring Active Galactic Nuclei with Nuclear Starburst Disks
We assess the potential of nuclear starburst disks to obscure the Seyfert-like AGN that dominate the hard X-ray background at z ∼ 1. Over 1200 starburst disk models, based on the theory developed by Thompson et al., are calculated for five input parameters: the black hole mass, the radial size of the starburst disk, the dustto-gas ratio, the efficiency of angular momentum transport in the disk,...
متن کاملRadio emission and active galactic nucleus feedback in post-starburst galaxies
We investigate radio-mode AGN activity among post-starburst galaxies from the Sloan Digital Sky Survey (SDSS) to determine whether AGN feedback may be responsible for the cessation of star formation. Based on radio morphology and radio loudness from the FIRST and NVSS data, we separate objects with radio activity due to an AGN from ongoing residual star formation. Of 513 SDSS galaxies with stro...
متن کاملStarburst or Seyfert? Adding a radio and far-infrared perspective to the investigation of activity in composite galaxies
It was once common to regard Seyfert and starburst galaxies as completely different types of object, but there is growing recognition that these classifications refer to the extremes of a continuous spectrum of galaxy types. In a previous study we investigated a sample of galaxies with ambiguous optical emission-line ratios and concluded from near-infrared spectroscopic observations that the sa...
متن کاملCola Ii - Radio and Spectroscopic Diagnostics of Nuclear Activity in Galaxies
We present optical spectroscopic observations of 93 galaxies taken from the infra-red selected COLA (Compact Objects in Low Power AGN) sample. These are all galaxies for which we have previously obtained low resolution radio observations and high resolution (< 0.05′′) Long Baseline Array (LBA) snapshots. The sample spans the range of far-IR luminosities from normal galaxies to LIRGs, and contai...
