Modelling the Far-Infrared emission in spyral galaxies
Simone Bianchi
This thesis presents an original model for the FIR emission in spirals, developed from an existing radiative transfer code (Bianchi, Ferrara & Giovanardi, 1996, ApJ, 465, 127). The…

ISO observations of spirals: modelling the FIR emission
Simone Bianchi, Paul B. Alton, Jonathan I. Davies
ISO observations at 200 micron have modified our view of the dust component in spiral galaxies. For a sample of seven resolved spirals we have retrieved a mean temperature of 20K,…

Dust Emissivity in the Far-Infrared
Simone Bianchi, Jonathan I. Davies, Paul B. Alton
We have derived the dust emissivity in the Far-Infrared (FIR) using data available in the literature. We use two wavelength dependences derived from spectra of Galactic FIR emissio…
