Star formation in the ultraluminous infrared galaxy F00183-7111 [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2014 Abstract We report the detection of molecular CO(1–0) gas in F00183-7111, one of the most extreme ultraluminous infrared galaxies (ULIRGs) known, with the Australia Telescope Compact Array. We measure a redshift of 0.3292 for F00183-7111 from the CO(1–0) line and estimate the mass of the molecular gas in 00183 to be 1 × 1010 M⊙.

The JCMT SCUBA-2 Survey of the James Webb Space Telescope North Ecliptic Pole Time-Domain Field
The Astrophysical Journal Supplement Series, 2023 The James Webb Space Telescope Time-Domain Field (JWST-TDF) is an ∼14′ diameter field near the North Ecliptic Pole that will be targeted by one of the JWST Guaranteed Time Observations programs. Here, we describe our James Clerk Maxwell Telescope SCUBA-2

Investigating the central engine of ultraluminous infrared galaxies: near infrared imaging [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We present 0.5-arcsec-resolution near-infrared images of six ultraluminous infrared galaxies with known redshifts. Six of the eight bright nuclei are resolved on kiloparsec scales, suggesting that there is significant circumnuclear star formation or close progenitor nuclei.

Ultraluminous infrared galaxies and the origin of quasars [PDF]
, 1988 An evolutionary connection between ultraluminous infrared galaxies and quasars is deduced from the observations of all 10 infrared galaxies with luminosities L(8-1000 μm) ≥ 10^(12) L⊙, taken from a flux-limited sample of infrared bright galaxies. Images

The Astrophysical JournalWe use the CN/CO intensity ratio to obtain the dense gas fraction, f _dense , for a sample of 16 ultraluminous and luminous infrared (IR) galaxies and compare f _dense with a suite of global galaxy properties.

Far-infrared metallicity diagnostics: application to local ultraluminous infrared galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 AbstractThe abundance of metals in galaxies is a key parameter that permits to distinguish between different galaxy formation and evolution models. Most of the metallicity determinations are based on optical line ratios. However, the optical spectral range is subject to dust extinction and, for high-z objects (z > 3), some of the lines used in ...

Optical polarimetry studies of Seyfert galaxies [PDF]
, 1999 Optical imaging polarimetry has been performed on seven nearby Seyfert galaxies, three with face-on and four with edge-on host galaxies of various morphological classifications.

An infrared study of a sample of optically selected galaxies [PDF]
, 1987 Infrared and optical photometry of a complete sub-sample of 194 galaxies in the Anglo-Australian Redshift Survey is presented. The Colour-Redshift diagrams are constructed and used, in a self-consistent manner, to reduce the data to zero-redshift colours

Comparison of dust-to-gas ratios in luminous, ultraluminous, and hyperluminous infrared galaxies
, 2007 19 pages+ 7 figures. in press in ANInternational audienceThe dust-to-gas ratios in three different samples of luminous, ultraluminous, and hyperluminous infrared galaxies are calculated by modelling their radio to soft X-ray spectral energy distributions
