We study the radio-FIR correlation between the nonthermal (synchrotron) radio continuum emission at λ90 cm (333 MHz) and the far-infrared emission due to cool (~20 K) dust at λ70 μm in spatially resolved normal galaxies at scales of ~1 kpc. The slope of the radio-FIR correlation significantly differs between the arm and interarm regions. However, this change is not evident at a lower wavelength of λ20 cm (1.4 GHz). We find the slope of the correlation in the arm to be 0.8 ± 0.12 and we use this… Expand
