The Nature of Ultraluminous Infrared Galaxies [PDF]
Symposium - International Astronomical Union, 2001 The Infrared Space Observatory (ISO) has for the first time made possible mid- and far-infrared spectroscopic studies of nearby and moderate redshift, dusty ultraluminous infrared galaxies (ULIRGs). We discuss recent SWS, LWS, ISOPHOT-S and ISOCAM (CVF) results on ULIRGs, addressing the following topics: What powers ULIRGs?

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 (

The Astrophysical Journal, 2023 We present the results of our ALMA ≲0.5 kpc resolution dense molecular line (HCN and HCO ^+ J = 2–1, J = 3–2, and J = 4–3) observations of 12 nearby (ultra)luminous infrared galaxies ([U]LIRGs). After matching beam sizes of all molecular line data to the

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.

Hidden Quasars in Ultraluminous Infrared Galaxies [PDF]
Symposium - International Astronomical Union, 1999 Many ultraluminous infrared galaxies (ULIRGs) are powered by quasars hidden in the center, but many are also powered by starbursts. A simply diagnostic diagram is proposed that can identify obscured quasars in ULIRGs by their high-ionization emission lines ([O III]λ5007/Hβ ≳ 5), and “warm” IR color (f25/f60≳ 0.25).

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 ...

Low Accretion Rates in Black Holes in Late-stage Merger Ultraluminous Infrared Galaxies
The Astrophysical JournalWe explore the accretion rates of supermassive black holes (SMBHs) in late-stage galaxy mergers by observing three ultraluminous infrared galaxies (ULIRGs), IRAS 14378-3651, IRAS 17208-0014 and IRAS 23365+3604, using the JWST/MIRI Medium Resolution ...
