Interstellar Dust Scattering Properties
Karl D. Gordon
Studies of dust scattering properties in astrophysical objects with Milky Way interstellar dust are reviewed. Such objects are reflection nebulae, dark clouds, and the Diffuse Gala…
SMC-Type Interstellar Dust in the Milky Way
Lynne A. Valencic, Geoffrey C. Clayton, Karl Gordon +1
It is well known that the sightline toward HD 204827 in the cluster Trumpler 37 shows an UV extinction curve that does not follow CCM. However, when a dust component, foreground to…
A Quantitative Comparison of SMC, LMC, and Milky Way UV to NIR Extinction Curves
Karl D. Gordon, Geoffrey C. Clayton, K. A. Misselt +2
We present an exhaustive, quantitative comparison of all of the known extinction curves in the Small and Large Magellanic Clouds (SMC and LMC) with our understanding of the general…
The Role of Polycyclic Aromatic Hydrocarbons in Ultraviolet Extinction. I. Probing small molecular PAHs
Geoffrey C. Clayton, Karl D. Gordon, Adolf N. Witt +7
We have obtained new STIS/HST spectra to search for structure in the ultraviolet interstellar extinction curve, with particular emphasis on a search for absorption features produce…
The Dust in Lyman Break Galaxies
Uma P. Vijh, Adolf N. Witt, Karl D. Gordon
We present our analysis of UV attenuation by internal dust of a large sample (N=906 galaxies) of Lyman Break Galaxies (LBGs). Using spectral energy distributions (SEDs) from the PÉ…
