چکیده

We report the detection of outflowing molecular gas in center nearby (z=0.014) massive radio galaxy NGC6328. The core galaxy, PKS B1718-649, is identified as a Gigahertz Peaked Spectrum source with compact (2 pc) double lobe morphology. used ALMA CO(2-1) and CO(3-2) observations at 100 pc resolution to study kinematics up ~5 kpc from center. While bulk settled highly warped disk, inner 300 disk along orientation jet, we high-excitation high-velocity that cannot be attributed any regular kinematic component based on our detailed 3D modeling data. dispersion also suggests it not part an inflowing, shredding structure. These results suggest presence outflow 3 8 solar masses per year. possibly originated interaction jet dense interstellar medium, even though emission detected closer than outflow. In this sense, resembles NGC1377, 4C31.04 ESO420-G13, which outflows are linked faint or past activity.

Gigahertz-Peaked Spectrum Radio Sources

The study of compact AGN which possess convex radio spectra (the gigahertz-peaked spectrum, or GPS sources) has generated a lot of interest over the last four decades, since these objects offer a unique opportunity to probe both the early evolutionary stages of relativistic AGN jets and their immediate nuclear environments. In this article I trace Ken Kellermann’s early investigations of these ...

Radio spectra of Gigahertz Peaked Spectrum radio sources

Awell defined sample of 72 Gigahertz Peaked Spectrum radio sources is compiled, having turnover frequencies in the range of 0.5 – 10 GHz. Using this sample, the canonical GPS radio spectrum is constructed, which is found to have a constant shape, independent of AGN type, redshift or radio luminosity. A possible deficiency of low turnover frequencies at high redshift is found, which may reflect ...

Evidence for Agn-driven Outflows in Young Radio Quasars

We present near-infrared spectra of young radio quasars (P1.4 GHz ≈ 26 − 27 W Hz−1) selected from the WideField Infrared Survey Explorer. The detected objects have typical redshifts of z ≈ 1.6 − 2.5 and bolometric luminosities ∼ 1047 erg s−1. Based on the intensity ratios of narrow emission lines, we find that these objects are mainly powered by active galactic nuclei (AGNs), although star form...

Jet-driven outflows of ionized gas in the nearby radio galaxy 3C 293

Fast outflows of gas, driven by the interaction between the radio jets and interstellar medium (ISM) of the host galaxy, are being observed in an increasing number of galaxies. One such example is the nearby radio galaxy 3C 293. In this paper we present integral field unit observations taken with OASIS on the William Herschel Telescope, enabling us to map the spatial extent of the ionized gas o...
