Dust Plasma Analogue for Interstellar 217.5 nm Extinction [PDF]
The new ultraviolet (UV) extinction measurements of carbonaceous nanoparticles in the range from 140 nm to 260 nm are presented. The plasma polymerized hydrocarbon nanoparticles were already proposed as a new astro analogue, which describe the infrared (

DIBs, Interstellar Dust, and Extinction [PDF]
AbstractThe relationship between DIBs and dust is still unknown. The correlation between reddening and DIB strength means that the DIBs are mixed in with the dust and gas in interstellar clouds. The DIBs are relatively stronger in the diffuse interstellar medium than in dense clouds.

On the Variation of Interstellar Dust Extinction [PDF]
Dust obscures astronomical observations and plays a important role in the evolution of galaxies. Mapping dust in three dimensions not only allows accurate correction of observations but also constrains the evolution of the interstellar medium (ISM). Extinction is the central observable to trace the density and properties of dust, and is widely employed

Interstellar Dust Models: Extinction, Absorption and Emission [PDF]
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 extinction, is described. It is used to calculate the infrared emission expected when such dust is heated by radiation with the spectrum of interstellar ...

The nature of interstellar dust as revealed by light scattering [PDF]
Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction.

Connecting the dusty dots: Dust depletion and extinction of local interstellar clouds
Investigating the chemical complexity of the interstellar medium (ISM) is key for understanding its physical nature and evolution. In this work, we studied parsec-scale interstellar dust clouds in the neutral ISM of the Milky Way using two different ...

SWIFTULTRAVIOLET OBSERVATIONS OF SUPERNOVA 2014J IN M82: LARGE EXTINCTION FROM INTERSTELLAR DUST [PDF]
We present optical and ultraviolet (UV) photometry and spectra of the very nearby and highly reddened supernova (SN) 2014J in M82 obtained with the Swift Ultra-Violet/Optical Telescope (UVOT). Comparison of the UVOT grism spectra of SN~2014J with Hubble Space Telescope observations of SN2011fe or UVOT grism spectra of SN~2012fr are consistent with an ...

We present the initial results of the Measuring Extinction and Abundances of Dust project, with a focus on the dust extinction features observed in our JWST near- and mid-infrared spectra of nine diffuse Milky Way sightlines (1.2 ≤ A ( V ) ≤ 2.5).
