Aeolian dust emission, transport and deposition in Western Libya by Elatrash, Mokhtar Salem

“…This research aims to explore the extent of dust activities in the western part of Libya, the main factors that influence dust entrainment and deposition, the likely regional emission sources transporting aerosol to this part of the country and ultimately to establish base line information in space and time based on a study area larger than the size of the UK. …”

No smoke without fire : cosmic dust emission as a tracer of star formation in galaxies by Bourne, Nathan

“…They re-radiate this energy as far-infrared radiation (wavelengths ~10-1000 microns), which can be detected from sources throughout the Universe by telescopes such as the Spitzer and Herschel space observatories. The spectral form of this radiation varies from one galaxy to another, depending on many factors such as the activity within the galaxy, the amount of dust, and the sources heating the dust. …”

“…We find that while many galaxies ( 56 per cent) are well fitted with the templates used to fit IRAS, Infrared Space Observatory (ISO) and Spitzer sources, for about half the galaxies two new templates are required: quiescent ('cirrus') models with colder (10-20 K) dust and a young starburst model with higher optical depth than Arp 220. …”

Gamma-ray burst afterglows as probes of environment and blast wave physics. I. Absorption by host-galaxy gas and dust by Starling, R., Wijers, R., Wiersema, K., Rol, E., Curran, Peter, Kouveliotou, C., van der Horst, A., Heemskerk, M.

“…We use a new approach to obtain limits on the absorbing columns toward an initial sample of 10 long gamma-ray bursts observed with BeppoSAX and selected on the basis of their good optical and near-infrared (NIR) coverage, from simultaneous fits to NIR, optical, and X-ray afterglow data, in count space and including the effects of metallicity. In no cases is a Milky Way-like ( MW) extinction preferred when testing MW, LMC, and SMC extinction laws. …”
