We examine the dust and gas properties of the nearby , barred galaxy M83 , which is part of the Very Nearby Galaxy Survey .
Using images from the PACS and SPIRE instruments of Herschel , we examine the dust temperature and dust mass surface density distribution .
We find that the nuclear , bar and spiral arm regions exhibit higher dust temperatures and masses compared to interarm regions .
However , the distribution of dust temperature and mass are not spatially coincident .
Assuming a trailing spiral structure , the dust temperature peaks in the spiral arms lie ahead of the dust surface density peaks .
The dust mass surface density correlates well with the distribution of molecular gas as traced by CO ( J=3 \rightarrow 2 ) images ( JCMT ) and the star formation rate as traced by H \alpha with a correction for obscured star formation using 24 \mu m emission .
Using H I images from THINGS to trace the atomic gas component , we make total gas mass surface density maps and calculate the gas-to-dust ratio .
We find a mean gas-to-dust ratio of 84 \pm 4 with higher values in the inner region assuming a constant CO-to-H _ { 2 } conversion factor .
We also examine the gas-to-dust ratio using CO-to-H _ { 2 } conversion factor that varies with metallicity .
