Obiettivo
"Interstellar dust is a fundamental component of the interstellar medium (ISM). By mediating key processes such as the absorption of stellar radiation, which is then re-emitted at infrared-mm wavelengths, it provides the necessary conditions (e.g. cloud cooling) for star formation to occur. Thus, dust determines the very processes that govern galaxy evolution. Dust is a ubiquitous component of the ISM in nearly all types of galaxies, even those at very high redshifts, where the dust has had little time to form. However, dust is an evolving component of the ISM, which responds to the local conditions. If we are to understand the processes that govern galaxy evolution it is therefore essential that we understand the evolving nature of dust in its relationship with the physical and dynamical conditions of the local ISM. The aim of this project is to study the evident synergy between interstellar gas and dust and to quantify the factors that drive dust evolution. This will be achieved by combining observations of a sample of photo-dissociation regions covering a range of local physical conditions, using the unique capabilities from ESA's newest IR space observatory, the Herschel space telescope, together with cutting edge expertise."
