Scientific paper

Observations with the Giant Metrewave Radio Telescope (GMRT) and the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope (JCMT) have recently revealed a sub-mm/radio correlation in the disks and high-latitudes of edge-on spiral galaxies. Along with evidence for this correlation, its origins and implications towards the famous FIR/radio correlation are discussed. The SCUBA observations at 450 and 850 microns have provided not only the means to calculate global dust temperature and mass, but also an unprecedented spatial description of the temperature and mass of cold dust in our sample. Finally, energy and temporal considerations for high-latitude dust are examined to help identify the means of dust transport to the halo.
