Quasars and Ultraluminous Infrared Galaxies: At the Limit? [PDF]

, 1998
We have detected the host galaxies of 16 nearby, radio-quiet quasars using images obtained with the Near-Infrared Camera and Multi-Object Spectrometer (NICMOS).

Nature of Widely Separated Ultraluminous Infrared Galaxies

The Astrophysical Journal, 2001
In the complete sample of ultraluminous infrared galaxies (ULIRGs) compiled by Kim (1995) about 5% consists of widely separated galaxies which are presumably in the early phase of interaction. This fact is contrary to the conventional view that ULIRGs are in the final stages of the merger of two gas-rich disk galaxies.

Evidence for a Molecular Cloud Origin for Gamma-Ray Bursts: Implications for the Nature of Star Formation in the Universe [PDF]

, 2001
It appears that the majority of rapidly-, well-localized gamma-ray bursts with undetected, or dark, optical afterglows, or `dark bursts' for short, occur in clouds of size R > 10L_{49}^{1/2} pc and mass M > 3x10^5L_{49} M_{sun}, where L is the isotropic ...

Hard X-Ray to Radio Multiwavelength SED Analysis of Local U/LIRGs in the GOALS Sample with a Self-consistent AGN Model including a Polar-dust Component

The Astrophysical Journal Supplement Series, 2023
We conduct hard X-ray to radio multiwavelength spectral energy distribution (SED) decomposition for 57 local luminous and ultraluminous infrared galaxies observed with the Nuclear Spectroscopic Telescope Array and/or Swift/Burst Alert Telescope in the ...

The Molecular Interstellar Medium in Ultraluminous Infrared Galaxies

, 1996
We present CO observations of a large sample of ultraluminous IR galaxies out to z = 0.3. Most of the galaxies are interacting, but not completed mergers. All but one have high CO(1-0) luminosities, log(Lco [K-km/s-pc^2]) = 9.92 +/- 0.12.

Imaging of Ultraluminous Infrared Galaxies in the Near-UV [PDF]

, 2000
We present the first ground-based U' (3410 angstroms) images of Ultraluminous Infrared Galaxies (ULIGs). Strong U' emission (median total M_U' = -20.8) is seen in all systems and in some cases the extended tidal features (both the smooth stellar ...

J0107a: A Barred Spiral Dusty Star-forming Galaxy at z = 2.467

The Astrophysical Journal Letters, 2023
Dusty star-forming galaxies (DSFGs) are among the most massive and active star-forming galaxies during the cosmic noon. Theoretical studies have proposed various formation mechanisms of DSFGs, including major merger-driven starbursts and secular star ...

The near-infrared morphology of ultraluminous infrared galaxies [PDF]

The Astrophysical Journal, 1990
Near-infrared images at 1.25, 1.65, and 2.2 microns have been obtained of nine galaxies from the IRAS Bright Galaxy Sample with infrared luminosities greater than 10 to the 12th solar luminosities. Two of the 2.2-micron images reveal previously undetected double nuclei, increasing the number of close double nuclei known for this samples from two to ...

CO Survey of High-z Radio Galaxies, Revisited with the Atacama Large Millimeter/submillimeter Array: Jet–Cloud Alignments and Synchrotron Brightening by Molecular Gas in the Circumgalactic Environment

The Astrophysical Journal, 2023
Powerful radio sources associated with supermassive black holes are among the most luminous objects in the universe, and are frequently recognized both as cosmological probes and active constituents in the evolution of galaxies.
