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.

NICMOS observations of luminous & ultraluminous infrared galaxies [PDF]

Astrophysics and Space Science, 1999
HST NICMOS observations of a sample of 24 luminous (LIGs: LIR[8-1000 μm] = 1011.0-11.99 L⊙) and ultraluminous (ULIGs:LIR ≳ 1012.0 L⊙) infrared galaxies are presented.The observations provide, for the first time, high resolution HST imagingof the imbedded 1.1 - 2.2 μm nuclear regions of these mergers.

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.

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.

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.

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 ...

Evidence of a Forming Nucleus in the Fourcade–Figueroa Galaxy

The Astrophysical Journal
We analyze data from the IRAS, Wide-field Infrared Survey Explorer, and Planck satellites, revealing an unresolved dust condensation at the center of the Fourcade–Figueroa galaxy (ESO270-G017), which may correspond to a forming nucleus.
