A deficit of ultraluminous X-ray sources in luminous infrared galaxies [PDF]

, 2014
We present results from a Chandra study of ultraluminous X-ray sources (ULXs) in a sample of 17 nearby (DL < 60 Mpc) luminous infrared galaxies (LIRGs), selected to have star formation rates (SFRs) in excess of 7 M⊙ yr −1 and low foreground Galactic ...

1.25 MM observations of luminous infrared galaxies [PDF]

Publications of the Astronomical Society of the Pacific, 1992
Measurements at a wavelength of 1.25 mm have been obtained for 17 IRAS galaxies selected on the basis of high far-infrared luminosity. These measurements are used to estimate the lower and upper limits to the mass of cold dust in infrared galaxies. As a lower limit on dust mass, all of the galaxies can be successfully modeled without invoking any dust ...

Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers

The Astrophysical Journal, 2023
Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

Comparing Ultraviolet and Infrared-Selected Starburst Galaxies in Dust Obscuration and Luminosity

, 2010
We present samples of starburst galaxies that represent the extremes discovered with infrared and ultraviolet observations, including 25 Markarian galaxies, 23 ultraviolet luminous galaxies discovered with GALEX, and the 50 starburst galaxies having the ...

THE FUV TO NEAR-IR MORPHOLOGIES OF LUMINOUS INFRARED GALAXIES IN THE GOALS SAMPLE [PDF]

, 2014
We compare the morphologies of a sample of 20 luminous infrared galaxies (LIRGs) from the Great Observatories All-sky LIRG Survey (GOALS) in the FUV, B, I, and H bands, using the Gini (G) and M20 parameters to quantitatively estimate the distribution and

A Complete 16 μm Selected Galaxy Sample at z ∼ 1. II. Morphological Analysis

The Astrophysical Journal
We present a morphological analysis of the 16 μ m flux-density-limited galaxy sample at 0.8 < z < 1.3 from Huang et al. (2021). At the targeted redshift, the 16 μ m emission corresponds to the polycyclic aromatic hydrocarbon feature from intense star ...

Dense Molecular Gas Properties of the Central Kiloparsec of Nearby Ultraluminous Infrared Galaxies Constrained by ALMA Three Transition-line Observations

The Astrophysical Journal, 2023
We report the results of Atacama Large Millimeter/submillimeter Array (ALMA) 1–2 kpc resolution, three rotational transition-line ( J = 2–1, J = 3–2, and J = 4–3) observations of multiple dense molecular gas tracers (HCN, HCO ^+ , and HNC) for 10 nearby (

A relation of the PAH 3.3 um feature with star-forming activity for galaxies with a wide range of infrared luminosity

, 2013
For star-forming galaxies, we investigate a global relation between polycyclic aromatic hydrocarbon (PAH) emission luminosity at 3.3 um, L_PAH3.3, and infrared (8-1000 um) luminosity, L_IR, to understand how the PAH 3.3 um feature relates to the star ...

The differential magnification of high-redshift ultraluminous infrared galaxies [PDF]

, 1998
A class of extremely luminous high-redshift galaxies has recently been detected in unbiased submillimetre-wave surveys using the Submillimetre Common-User Bolometer Array (SCUBA) camera at the James Clerk Maxwell Telescope.

Radio continuum properties of luminous infrared galaxies. Identifying the presence of an AGN in the radio [PDF]

, 2014
Luminous infrared galaxies are systems enshrouded in dust, which absorbs most of their optical/UV emission and re-radiates it in the mid- and far-infrared.
