Spitzer's View of Edge-on Spirals
B. W. Holwerda, R. S. de Jong, A. Seth +4
Edge-on spiral galaxies offer a unique perspective on disks. One can accurately determine the height distribution of stars and ISM and the line-of-sight integration allows for the…

Radiative Transfer in Spiral Galaxies
Simone Bianchi
The internal dust extinction in spiral galaxies can affect our understanding of their structure and morphology, as well as our perception of the distant universe in the background.…
Exploring the Lyman Forest with VLT/UVES
S. Cristiani, S. Bianchi, S. D'Odorico +1
A sample of 8 QSOs with 1.7 < z_em < 3.7 has been observed with VLT/UVES at a typical resolution 45000 and S/N~40-50. Thanks to the two-arm design of the spectrograph, a remarkable…
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,…
