Relating spatially resolved optical attenuation, dust and gas in nearby galaxies

E. D. Paspaliaris, S. Bianchi, E. Corbelli +1

We relate the optical attenuation inferred by the Balmer decrement, $A_{V,\mathrm{BD}}$, and by the SED-fitting, $A_{V,\mathrm{SED}}$, to the dust distribution and gas surface dens…
