Millimeter Interferometric Investigations of the Energy Sources of Three Ultraluminous Infrared Galaxies, UGC 5101, Mrk 273, and IRAS 17208-0014, based on HCN to HCO+ Ratios

, 2006
We present interferometric observations of three ultraluminous infrared galaxies (ULIRGs; UGC 5101, Mrk 273, and IRAS 17208-0014) in the 3-mm wavelength range, using the Nobeyama Millimeter Array.

Dynamical Masses in Luminous Infrared Galaxies

, 2006
We have studied the dynamics and masses of a sample of ten nearby luminous and ultraluminous infrared galaxies (LIRGS and ULIRGs), using 2.3 micron CO absorption line spectroscopy and near-infrared H- and Ks-band imaging.

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.

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 ...

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.

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.
