Physical dust models are presented for 65 galaxies in SINGS that are strongly detected in the four IRAC bands and three MIPS bands. For each galaxy we estimate (1) the total dust mass, (2) the fraction of the dust mass contributed by PAHs, and (3) the intensity of the starlight heating the dust grains. We find that spiral galaxies have dust properties resembling the dust in the local region of the Milky Way, with similar dust-to-gas ratio and similar PAH abundance. The observed SEDs, including… 

Dust in the SINGS galaxy sample

Dust models have been applied to interpret the IR emission from 65 galaxies in the SINGS galaxy survey, allowing dust masses, PAH fractions, and starlight intensities to be determined. The dust

Interstellar dust models: Extinction, absorption and emission

The observational constraints on interstellar dust are summarized. A dust model, consisting of a mixture of amorphous silicate, graphite, and PAH material that reproduces the observed interstellar

MODELING DUST AND STARLIGHT IN GALAXIES OBSERVED BY SPITZER AND HERSCHEL: NGC 628 AND NGC 6946

We characterize the dust in NGC 628 and NGC 6946, two nearby spiral galaxies in the KINGFISH sample. With data from 3.6 μm to 500 μm, dust models are strongly constrained. Using the Draine & Li dust

The dust content of the most metal-poor star-forming galaxies

Although dust content is usually assumed to depend uniquely on metallicity, recent observations of two extremely metal-poor dwarf galaxies have suggested that this may not always be true. At a

Context. The dust properties in dwarf galaxies have been a matter of debate. High resolution data from SPITZER, HERSCHEL and PLANCK allow us to probe the entire spectral energy distribution (SED) of

Stellar, Gas, and Dust Emission of Star-forming Galaxies out to z ∼ 2

While dust is a major player in galaxy evolution, its relationship with gas and stellar radiation in the early universe is still not well understood. We combine 3D-Hubble Space Telescope

DUST ATTENUATION IN DISK-DOMINATED GALAXIES: EVIDENCE FOR THE 2175 Å DUST FEATURE

The attenuation of starlight by interstellar dust is investigated in a sample of low-redshift, disk-dominated star-forming galaxies using photometry from GALEX and SDSS. By considering broadband

Dust properties of Lyman-break galaxies in cosmological simulations

Recent observations have indicated the existence of dust in high-redshift galaxies, however, the dust properties in them are still unknown. Here we present theoretical constraints on dust properties

Simulating the dust content of galaxies: successes and failures

We present full-volume cosmological simulations, using the moving-mesh code AREPO to study the coevolution of dust and galaxies. We extend the dust model in AREPO to include thermal sputtering of

THE EVOLUTION OF INTERSTELLAR MEDIUM MASS PROBED BY DUST EMISSION: ALMA OBSERVATIONS AT z = 0.3–2

The use of submillimeter dust continuum emission to probe the mass of interstellar dust and gas in galaxies is empirically calibrated using samples of local star-forming galaxies, Planck observations
