We propose to use the PHT-C camera on the ISO to make fully-sampled maps of the far-infrared continuum emission in two nearby spiral galaxies, Maffei 2 and IC 342. These galaxies are sufficiently close that ISO maps can distinguish different regions within the disk, such as spiral arms and nuclear star-forming complexes. We plan to fully map the optical extent of both galaxies at 60, 100, and 160um. Multi-wavelength maps allow the study of dust emission properties such as luminosity and color across the disks of the galaxies. We will compare the far-infrared images of the two galaxies with CO, HI, radio continuum, and near-infrared images. The goal of the project is to study how dust temperatures, luminosities (star formation rate), and luminosity-to-mass ratios (star formation efficiencies) vary with location and gas properties in two representative normal spiral galaxies.
