Molecular Gas Distribution in Double-Nucleus Ultraluminous Infrared Galaxies
Millimeter (CO) observations of 5 double-nucleus ultraluminous infrared galaxy (ULIG) mergers are presented. With nuclear separations of 3 − 5 kpc, these galaxies are in the “intermediate” stages of the merger process. A preliminary comparison of the distribution of molecular gas (the likely fuel source for both starbursts and active galactic nuclei: AGN) shows a tendency for molecular gas to b...
متن کاملEnormous disc of cool gas surrounding the nearby powerful radio galaxy NGC 612 ( PKS 0131 - 36 )
We present the detection of an enormous disc of cool neutral hydrogen (H I) gas surrounding the S0 galaxy NGC 612, which hosts one of the nearest powerful radio sources (PKS 0131-36). Using the Australia Telescope Compact Array, we detect MHI = 1.8 × 10 9M⊙ of H I emission-line gas that is distributed in a 140 kpc wide disc-like structure along the optical disc and dust-lane of NGC 612. The bul...
متن کاملRadio jet interactions in the radio galaxy PKS 2152 - 699
We present radio observations of the radio galaxy PKS 2152-699 obtained with the Australia Telescope Compact Array (ATCA). The much higher resolution and s/n of the new radio maps reveals the presence of a bright radio component about 10 arcsec NE of the nucleus. This lies close to the highly ionized cloud previously studied in the optical and here shown in a broadband red snapshot image with t...

متن کاملThe Active Nucleus in the Ultraluminous Infrared Galaxy IRAS 08311 − 2459
Near-infrared spectroscopy using the new Palomar Integral Field Spectrograph indicates the presence of an AGN (active galactic nucleus) in the ultraluminous infrared galaxy IRAS 08311−2459. The high-velocity wings of the Paschen-α hydrogen recom-bination line are seen to be spatially unresolved, and with no positional offset between red and blue high velocity emission. The [Si VI] coronal line,...
