Abstract
Dust is a crucial component in the interstellar medium of galaxies. It regulates several physical and chemical processes. Dust grains are also efficient at absorbing and scattering ultraviolet/optical photons and then re-radiating the absorbed energy in the infrared/submm wavelength range. The spatial distribution and properties of dust in galaxies can hence be investigated in two complementary ways: by its attenuation effects at short wavelengths, and by its thermal emission at long wavelengths. Both approaches have their advantages and challenges. In this contribution, we discuss a number of recent interesting results on interstellar dust in nearby galaxies, obtained by our research group at Ghent University.
