Infrared polarimetry of galaxies. I - Infrared luminous galaxies
The Astrophysical Journal, 1989 Les observations polarimetriques a 1.2, 1.65 et 2.2 μm sont presentees pour les noyaux de 6 galaxies IR lumineuses: IRAS 05189-2524, UGC 5101, Mrk 231, Mrk 273, Arp 220 et NGC 6240. Les nombreux mecanismes et les geometries responsables de la production de la polarisation dans le proche IR sont discutes en ...

A Spitzer study of interacting luminous and ultra-luminous infrared galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractWe conducted a Spitzer Space Telescope survey of 28 Luminous (11 < log (LIR/L⊙) < 12, LIRGs) and Ultra-Luminous Infrared Galaxies (log (LIR/L⊙) > 12, ULIRGs). Many of these galaxies are found in pairs or associations and are powered by either nuclear activity or star-formation (Sanders & Mirabel 1996).

GOALS-JWST: Hidden Star Formation and Extended PAH Emission in the Luminous Infrared Galaxy VV 114
The Astrophysical Journal Letters, 2022 James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) images of the luminous infrared (IR) galaxy VV 114 are presented. This redshift ∼0.020 merger has a western component (VV 114W) rich in optical star clusters and an eastern component (VV ...

Mid-Infrared Spectral Diagnostics of Luminous Infrared Galaxies [PDF]
AIP Conference Proceedings, 2010 We present a statistical analysis of 248 luminous infrared galaxies (LIRGs) which comprise the Great Observatories All‐sky LIRG Survey (GOALS) observed with the Infrared Spectrograph (IRS) on‐board Spitzer in the rest‐frame wavelength range between 5 and 38 μm.

Star-formation histories of local luminous infrared galaxies [PDF]
Astronomy & Astrophysics, 2015 We present the analysis of the integrated spectral energy distribution (SED) from the ultraviolet (UV) to the far-infrared and H$ $ of a sample of 29 local systems and individual galaxies with infrared (IR) luminosities between 10^11 Lsun and 10^11.8 Lsun.

GOALS-JWST: Resolving the Circumnuclear Gas Dynamics in NGC 7469 in the Mid-infrared
The Astrophysical Journal Letters, 2022 The nearby, luminous infrared galaxy NGC 7469 hosts a Seyfert nucleus with a circumnuclear star-forming ring and is thus the ideal local laboratory for investigating the starburst–AGN (active galactic nucleus) connection in detail.
