Rotating Nuclear Rings and Extreme Starbursts in Ultraluminous Galaxies

, 1998
New high resolution interferometer data of 10 IR ultraluminous galaxies shows the molecular gas is in rotating nuclear rings or disks with radii 300 to 800 pc.

Implication of Galaxy-scale Negative Feedback by One of the Most Powerful Multiphase Outflows in a Hyperluminous Infrared Galaxy at Intermediate Redshift

The Astrophysical Journal
Powerful galactic outflows driven by active galactic nuclei (AGNs) are commonly considered as one of the main mechanisms to regulate star formation in massive galaxies.

Ultraluminous infrared galaxies: Starburst vs. AGN

Advances in Space Research, 1999
Abstract We have obtained ISOPHOT-S low resolution mid-infrared spectra of a sample of 60 Ultraluminous Infrared Galaxies (ULIRGs). We use the strength of the ‘PAH’ mid-infrared features as a discriminator between starburst and AGN activity, and to probe for evolutionary effects. Observed ratios of PAH features in ULIRGs differ slightly from those in

The SUPERCOLD-CGM Survey. II. [C i](1–0) Emission and the Physical Conditions of Cold Gas in Enormous Lyα Nebulae at z ∼ 2

The Astrophysical Journal
We report Atacama Large Millimeter/submillimeter Array and Atacama Compact Array observations of atomic carbon ([C i ](1–0)) and dust continuum in 10 enormous Ly α nebulae hosting ultraluminous Type-I QSOs at z = 2.2–2.5, as part of the Survey of ...
