Analysis of the spatially-resolved $V$-3.6$\mu$m colors and dust extinction in 257 nearby NGC and IC galaxies

Duho Kim, Rolf A. Jansen, Rogier A. Windhorst +2

We present and analyze spatially-resolved maps for the observed $V$- and $g$-band to 3.6$\mu$m flux ratios and the inferred dust extinction values, $A_V$, for a sample of 257 nearby…
