We present an initial look at the far infrared-radio correlation within the star-forming disks of four nearby, nearly face-on galaxies (NGC~2403, NGC~3031, NGC~5194, and NGC~6946). Using {\it Spitzer} MIPS imaging and WSRT radio continuum…

We observed M51 at three frequencies, 1.4GHz (20cm), 4.9GHz (6cm) and 8.4GHz (3.6cm), with the VLA and the Effelsberg 100m telescope to obtain the highest quality radio continuum images of a nearby spiral galaxy. These radio data were…

We investigate the scale on which the correlation arises between the 843 MHz radio and the 60 micron far-infrared (FIR) emission from star forming regions in the Milky way. The correlation, which exists on the smallest scales investigated…

(Abridged) We present an initial look at the far infrared-radio correlation within the star-forming disks of four nearby, nearly face-on galaxies (NGC 2403, NGC 3031, NGC 5194, and NGC 6946). Using Spitzer MIPS imaging and WSRT radio…

We study the radio - far-infrared (FIR) correlation in a sample of faint dwarf irregular galaxies using NVSS data for 1.4 GHz radio flux, Spitzer MIPS 70 um data for FIR flux, and GALEX FUV data to estimate the star formation rates (SFR).…
