Viewing the Dusty Universe - Dr Cristina C. Popescu Colloquium

ATNF Marsfield Lecture Theatre

Abstract

Understanding dust emission is crucial to the
understanding of the physical processes in galaxies and of the
star-formation
history of the Universe as a whole. The obvious
starting point to gain such an understanding is to look
at emission from grains in star-forming galaxies in the Local
Universe, also with respect to stellar emission, and to model the
spectral energy distributions of these galaxies from the ultraviolet to the
far-infrared/submillimeter. In this talk I will present recent progress
in the characterisation of dust emission from spiral and dwarf galaxies
based
on observations made with cryogenic-cooled orbiting telescopes, and I will
describe theoretical developments in the interpretation of multi-wavelength
observations in terms of the intrinsic physical properties of these systems.
