Dust Absorption toward Supernova Remnant W44

The Astronomical Journal
Supernova remnants (SNRs) can strongly affect the chemical composition of the interstellar dust. In this paper, we investigate to what degree the dust and ices are modified by observing four stars expected to be absorbed by a giant molecular cloud ...

Modeling of diffuse molecular gas applied to HD 102065 observations

, 2008
Aims. We model a diffuse molecular cloud present along the line of sight to the star HD 102065. We compare our modeling with observations to test our understanding of physical conditions and chemistry in diffuse molecular clouds. Methods.

Gamma-ray emission from molecular clouds with the Cherenkov Telescope Array and the cosmic ray spectrum in the Galaxy [PDF]

, 2022
In this work we calculate the diffuse emission from molecular clouds (MCs) in the Galaxy at very high energy (from hundreds of GeV to hundreds of TeV).We present the results from the analysis of the simulated emission of these sources as it will be ...

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Ambipolar Diffusion in Molecular Cloud Cores and the Gravomagneto Catastrophe [PDF]

The Astrophysical Journal, 2007
This paper re-examines the problem of ambipolar diffusion as a mechanism for the production and runaway evolution of centrally condensed molecular cloud cores, a process that has been termed the gravomagneto catastrophe. Our calculation applies in the geometric limit of a highly flattened core and allows for a semi-analytic treatment of the full ...
