Search for tidal dwarf galaxy candidates in a sample of ultraluminous infrared galaxies [PDF]

Astronomy & Astrophysics, 2007
(ABRIDGED) Star-forming small galaxies made out of collisional debris have been found in a variety of merging systems. So far only a few of them are known in ULIRGs although they show clear signs of interactions. Whether external star formation may take place in such objects is an open question. The aim of this paper is to identify and characterise the

Infrared emission from z ∼ 6.5 quasar host galaxies: a direct estimate of dust physical properties

Astronomy & Astrophysics
Quasars at the dawn of cosmic time (z > 6) are fundamental probes for investigating the early coevolution of supermassive black holes and their host galaxy.

FAR-INFRARED FINE-STRUCTURE LINE DIAGNOSTICS OF ULTRALUMINOUS INFRARED GALAXIES [PDF]

The Astrophysical Journal, 2013
We present Herschel observations of six fine-structure lines in 25 Ultraluminous Infrared Galaxies at z<0.27. The lines, [O III]52, [N III]57, [O I]63, [N II]122, [O I]145, and [C II]158, are mostly single gaussians with widths <600 km s-1 and luminosities of 10^7 - 10^9 Solar.

Spitzer Mid-Infrared Imaging of Nearby Ultraluminous Infrared Galaxies [PDF]

, 2006
We have observed 14 nearby (z < 0.16) Ultraluminous Infrared Galaxies (ULIRGs) with Spitzer at 3.6-24μm. The underlying host galaxies are well-detected, in addition to the luminous nuclear cores. While the spatial resolution of Spitzer is poor, the great

Near-Infrared Imaging of Ultraluminous IRAS Galaxies

, 1994
IRAS discovered a class of objects which emit most of their radiation at infrared wavelengths and which possess bolometric luminosities comparable to those of classical quasars.

A JWST MIRI LRS Survey of 37 Massive Star-forming Galaxies and Active Galactic Nuclei at Cosmic Noon: Overview and First Results

The Astrophysical Journal
We present a large spectroscopic survey with JWST’s Mid-Infrared Instrument Low Resolution Spectrometer (LRS) targeting 37 infrared-bright galaxies between z  = 0.65–2.46 with infrared luminosities $\mathrm{log}{L}_{{\rm{IR}}}/{L}_{\odot }\gt 11.5$ and $\

PASSAGES: The Wide-ranging, Extreme Intrinsic Properties of Planck-selected, Lensed Dusty Star-forming Galaxies

The Astrophysical Journal
The PASSAGES (Planck All-Sky Survey to Analyze Gravitationally-lensed Extreme Starbursts) collaboration has recently defined a sample of 30 gravitationally lensed dusty star-forming galaxies (DSFGs). These rare, submillimeter-selected objects enable high-

Ultraluminous Infrared Galaxies: Power Sources and Ages Along the Merger Sequence [PDF]

, 2000
Ultraluminous infrared galaxies (ULIRGs) are the most luminous galaxies in the local universe, with power outputs above 10¹² times that of our sun. Almost all ULIRGs are found to be associated with collisions between large, gas-rich galaxies.
