Optical Properties of 4248 IRAS Galaxies

open access: yes, 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 ...

The Structure of IR Luminous Galaxies at 100 Microns [PDF]

open access: yes, 2000
We have observed twenty two galaxies at 100 microns with the Kuiper Airborne Observatory in order to determine the size of their FIR emitting regions. Most of these galaxies are luminous far-infrared sources, with L_FIR > 10^11 L_sun.

[Ultra] luminous infrared galaxies selected at 90 μm in the AKARI deep field: a study of AGN types contributing to their infrared emission [PDF]

open access: yes, 2016
Aims. The aim of this work is to characterize physical properties of ultra luminous infrared galaxies (ULIRGs) and luminous infrared galaxies (LIRGs) detected in the far-infrared (FIR) 90 μ m band in the AKARI Deep Field-South (ADF-S) survey.

Silicates in Ultraluminous Infrared Galaxies

open access: yesThe Astrophysical Journal, 2008
We analyze the mid-infrared (MIR) spectra of ultraluminous infrared galaxies (ULIRGs) observed with the Spitzer Space Telescope's Infrared Spectrograph. Dust emission dominates the MIR spectra of ULIRGs, and the reprocessed radiation that emerges is independent of the underlying heating spectrum.

A Catalog of Luminous Infrared Galaxies in the IRAS Survey and the Second Data Release of the SDSS

open access: yes, 2005
We select the Luminous Infrared Galaxies by cross-correlating the Faint Source Catalogue (FSC) and Point Source Catalogue (PSC) of the IRAS Survey with the Second Data Release of the SDSS for studying their infrared and optical properties.

Spitzer Observations of Passive and Star Forming Early-type Galaxies: an Infrared Color-Color Sequence

open access: yes, 2009
We describe the infrared properties of a large sample of early type galaxies, comparing data from the Spitzer archive with Ks-band emission from 2MASS.

Decomposing Star Formation and Active Galactic Nucleus with Spitzer Mid-Infrared Spectra: Luminosity Functions and Co-Evolution [PDF]

open access: yes, 2010
We present Spitzer 7-38um spectra for a 24um flux limited sample of galaxies at z~0.7 in the COSMOS field. The detailed high-quality spectra allow us to cleanly separate star formation (SF) and active galactic nucleus (AGN) in individual galaxies.

Exploring the molecular chemistry and excitation in obscured luminous infrared galaxies - An ALMA mm-wave spectral scan of NGC 4418 [PDF]

open access: yes, 2015
Context. Extragalactic observations allow the study of molecular chemistry and excitation under physical conditions which may differ greatly from those found in the Milky Way.

A relation of the PAH 3.3 um feature with star-forming activity for galaxies with a wide range of infrared luminosity

open access: yes, 2013
For star-forming galaxies, we investigate a global relation between polycyclic aromatic hydrocarbon (PAH) emission luminosity at 3.3 um, L_PAH3.3, and infrared (8-1000 um) luminosity, L_IR, to understand how the PAH 3.3 um feature relates to the star ...
