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).

The stellar, molecular gas and dust content of the host galaxies of two z~2.8 dust obscured quasars [PDF]

, 2011
We present optical through radio observations of the host galaxies of two dust obscured, luminous quasars selected in the mid-infrared, at z=2.62 and z=2.99, including a search for CO emission.

The Role of AGN in Luminous Infrared Galaxies from the Multiwavelength Perspective

Universe, 2022
Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes.

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.

GOALS-JWST: NIRCam and MIRI Imaging of the Circumnuclear Starburst Ring in NGC 7469

The Astrophysical Journal Letters, 2023
We present James Webb Space Telescope (JWST) imaging of NGC 7469 with the Near-Infrared Camera and the Mid-InfraRed Instrument. NGC 7469 is a nearby, z = 0.01627, luminous infrared galaxy that hosts both a Seyfert Type-1.5 nucleus and a circumnuclear ...

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.

The Interaction between AGN and Starburst Activity in the Circumnuclear Region of NGC 7469 as Viewed with JWST

The Astrophysical Journal Letters, 2023
We combine mid-infrared diagnostics obtained from integral-field-unit observations taken with Mid-Infrared Instrument/Medium Resolution Spectrograph on the James Webb Space Telescope with cold molecular gas information derived from Atacama Large ...

An ISOCAM survey through gravitationally lensing galaxy clusters. III. New results from mid-infrared observations of th e cluster Abell 2219 [PDF]

, 2004
The massive cluster of galaxies Abell 2219 (z = 0.228) was observed at 14.3 $\mu$m with the Infrared Space Observatory and results were published by Barvainis et al. (1999). These observations have been reanalyzed using a method specifically designed for

Optical Properties of 4248 IRAS Galaxies

, 2005
We have investigated optical properties of 4248 infrared galaxies (IRGs) by positionally matching data from the IRAS and the SDSS DR3. Our sample includes 3 hyper luminous infrared galaxies (L >10^13Lsun) and 178 ultra luminous infrared galaxies (10 ...
