The resolved scaling relations in DustPedia: Zooming in on the local Universe

Understand

We perform a homogeneous analysis of an unprecedented set of spatially resolved scaling relations (SRs) between ISM components and other properties in the range of scales 0.3-3.4 kpc.

• We also study some ratios: dust-to-stellar, dust-to-gas, and dust-to-metal.
• We use a sample of 18 large, spiral, face-on DustPedia galaxies.
• All the SRs are moderate/strong correlations except the dust-HI SR that does not exist or is weak for most galaxies.
