TL;DR: The SIRTF Nearby Galaxy Survey (SINGS) as mentioned in this paper is a comprehensive infrared imaging and spectroscopic survey of 75 nearby galaxies and its primary goal is to characterize the infrared emission of galaxies and their principal infrared-emitting components across a broad range of galaxy properties and star formation environments.
Journal ArticleDOI
Dust Masses, PAH Abundances, and Starlight Intensities in the SINGS Galaxy Sample
Bruce T. Draine,Daniel A. Dale,George J. Bendo,Karl D. Gordon,J. D. T. Smith,Lee Armus,Charles W. Engelbracht,George Helou,Robert C. Kennicutt,Robert C. Kennicutt,Aigen Li,Helene Roussel,Fabian Walter,Daniela Calzetti,John Moustakas,John Moustakas,Eric J. Murphy,George H. Rieke,Caroline Bot,David Hollenbach,Kartik Sheth,Harry I. Teplitz +21 more
TL;DR: Physical dust models for 65 galaxies in SINGS that are strongly detected in the four IRAC bands and three MIPS bands were presented for each galaxy as discussed by the authors, estimating the total dust mass, the fraction of the dust mass contributed by PAHs, and the intensity of the starlight heating the dust grains.

TL;DR: In this paper, the authors analyzed Spitzer 8 and 24 μm data of star-forming regions in a sample of 33 nearby galaxies with available HST NICMOS images in the Paα (1.8756 μm) emission line.

The Mid-Infrared Spectrum of Star-Forming Galaxies: Global Properties of PAH Emission
J. D. T. Smith,Bruce T. Draine,Daniel A. Dale,John Moustakas,Robert C. Kennicutt,George Helou,L. Armus,H. Roussel,Kartik Sheth,George J. Bendo,B. A. Buckalew,D. Calzetti C. W. Engelbracht,Karl D. Gordon,D. J. Hollenbach,Aigen Li,S. Malhotra,Eric J. Murphy,Fabian Walter +17 more
TL;DR: In this article, a sample of low-resolution 5-38um Spitzer IRS spectra of the inner few square kiloparsecs of 59 nearby galaxies spanning a large range of star formation properties is presented, and a robust method for decomposing mid-infrared galaxy spectra is described, and used to explore the behavior of PAH emission and the prevalence of silicate dust extinction.
