VLBI Imaging of Luminous Infrared Galaxies : AGN Cores in Mrk 231 , UGC 5101 & NGC 7469
نویسنده
چکیده
We report 18cm VLBI continuum imaging observations at ∼5 milliarcsecond resolution for UGC 5101, NGC 7469, and Mrk 231, all part of a sample of Luminous Infrared Galaxies which have been shown to have strong VLBI radio cores in a previous 18cm VLBI survey. Mrk 231, generally considered to be a dust-enshrouded QSO, shares many characteristics with quasars, including a broad, Sy1 optical emission spectrum, optical and radio variability, and broadabsorption-line (BAL) spectrum. NGC 7469 is a classical Sy1 galaxy and UGC 5101 is a liner system.

The Luminous Starburst Ring in NGC 7771: Sequential Star Formation?
Only two of the twenty highly luminous starburst galaxies analyzed by Smith et al. exhibit circumnuclear rings of star formation. These galaxies provide a link between ∼ 10L⊙ luminosity class systems and classical, less–luminous ringed systems. In this paper, we report the discovery of a near–infrared counterpart to the 1.6 kpc diameter nuclear ring of radio emission in NGC 7771 (UGC 12815). Th...
متن کاملMid-Infrared Images of Luminous Infrared Galaxies in a Merging Sequence
We report mid-infrared observations of several luminous infrared galaxies (LIGs) carried out with the Infrared Space Observatory (ISO). Our sample was chosen to represent different phases of a merger sequence of galaxy-galaxy interaction with special emphasis on early/intermediate stages of merging. The mid-infrared emission of these LIGs shows extended structures for the early and intermediate...
متن کاملRadio Agns among Luminous Infrared Galaxies
An analysis of radio and FIR emission in over 1500 IRAS selected galaxies produces a good linear correlation between radio and FIR luminosity, indicating that star formation in normal eld galaxies dominates the infrared luminosity in the local volume. Galaxies with clear radio-excess (deened as having at least 5 times larger radio ux over expected from FIR) are identiied as hosting a radio AGN,...
متن کاملInfrared Surveys for AGN
From the earliest extragalactic infrared studies AGN have shown themselves to be strong infrared sources and IR surveys have revealed new populations of AGN. I briefly review current motivations for AGN surveys in the infrared and results from previous IR surveys. The Luminous Infrared Galaxies, which in some cases house dust-enshrouded AGN, submillimeter surveys, and recent studies of the cosm...
متن کاملNICMOS Imaging of Infrared-Luminous Galaxies
We present near-infrared images obtained with the HST NICMOS camera for a sample of 9 luminous (LIGs: LIR(8 − 1000μm) ≥ 10 11 L⊙) and 15 ultra-luminous (ULIGS: LIR ≥ 10 12 L⊙) infrared galaxies. The sample includes representative systems classified as warm (f25μm/f60μm > 0.2) and cold (f25μm/f60μm ≤ 0.2) based on the mid-infrared colors and systems with nuclear emission lines classified as HII ...
