Magellanic Cloud-Type Interstellar Dust along Low-Density Sight Lines in the Galaxy

  title={Magellanic Cloud-Type Interstellar Dust along Low-Density Sight Lines in the Galaxy},

We have studied the UV extinction properties along 30 Galactic sight lines using data from the International Ultraviolet Explorer archive that have never been previously examined. These distant (d > 1 kpc) sight lines were selected to investigate the distribution and physical conditions of gas located in low-density regions of the Galactic disk and halo. The average densities along these sight lines are extremely low. It is likely that they are dominated by the warm intercloud medium and have…

Small Magellanic Cloud-Type Interstellar Dust in the Milky Way
It is well known that the sight line toward HD 204827 in the cluster Trumpler 37 shows a UV extinction curve that does not follow the average Galactic extinction relation. However, when a dust
New Ultraviolet Extinction Curves for Interstellar Dust in M31
New low-resolution UV spectra of a sample of reddened OB stars in M31 were obtained with HST/STIS to study the wavelength dependence of interstellar extinction and the nature of the underlying dust
Extinction Law Variations and Dust Excitation in the Spiral Galaxy NGC 300
We investigate the possible origin of the strong radial gradient in the ultraviolet-to-infrared ratio in the nearby late-type spiral galaxy NGC 300 and emphasize the importance of local variations in
We have assembled a homogeneous database of 417 ultraviolet (UV) extinction curves for reddened sight lines having International Ultraviolet Explorer spectra. We have combined these with optical and

Global spectral energy distributions of the Large Magellanic Cloud with interstellar dust
The effects of dust on infrared emission vary among galaxies of different morphological types. We investigated integrated spectral energy distributions (SEDs) in infrared and submillimeter/millimeter

The recent discovery that the ultraviolet (UV) dust extinction in starburst galaxies is similar to that found in the Small Magellanic Cloud (SMC) motivated us to reinvestigate the UV extinction found
