Hα Velocity Mapping of Ultraluminous Infrared Galaxies

The Astrophysical Journal, 1998
We use imaging Fabry-Pec rot observations to explore the dynamical conditions in four southern ultra- luminous infrared galaxies. These galaxies all show morphological and kinematic fea- (L IR Z 1012 L _ ) tures indicative of a major merger, but they span a wide range of inferred dynamical ages: the youngest system is just past the -rst encounter ...

A Comparative Study of Ultraluminous Infrared Galaxies in the IRAS and SDSS Surveys

The Astrophysical Journal Supplement Series
We present a comprehensive study of ultraluminous infrared galaxies (ULIRGs), leveraging data from the Infrared Astronomical Satellite Faint Source Catalogue and the spectroscopic catalog in the Sloan Digital Sky Survey Data Release 16.

The Merger-Triggered Active Galactic Nuclei Contribution to the Ultraluminous Infrared Galaxy Population

, 2012
It has long been thought that there is a connection between ultraluminous infrared galaxies (ULIRGs), quasars, and major mergers. Indeed, simulations show that major mergers are capable of triggering massive starbursts and quasars.

Massive Accretion Disks [PDF]

, 1999
Recent high resolution near infrared (HST-NICMOS) and mm-interferometric imaging have revealed dense gas and dust accretion disks in nearby ultra-luminous galactic nuclei.

Molecular Gas in the Powerful Radio Galaxies 3C~31 and 3C~264: Major or Minor Mergers?

, 2000
We report the detection of $^{12}$CO~($1 \to 0$) and $^{12}$CO~($2 \to 1$) emission from the central regions ($\lesssim 5$--$10 {\rm kpc}$) of the two powerful radio galaxies 3C~31 and 3C~264.

On the Origin of Lyman$\alpha$ Blobs at High Redshift: Submillimetric Evidence for a Hyperwind Galaxy at z=3.1

, 2001
The most remarkable class of high-redshift objects observed so far is extended Ly$\alpha$ emission-line blobs found in an over-density region at redshift 3.1.

Ionized Carbon in Galaxies: The [C ii] 158 μm Line as a Total Molecular Gas Mass Tracer Revisited

The Astrophysical Journal
In this paper, we present a statistical study of the [C ii ] 158 μ m line and the CO(1−0) emission for a sample of ∼200 local and high- z (32 sources with z > 1) galaxies with very different physical conditions.
