Description
I will present a morphological analysis of a set of spiral galaxies from the NIKA2 Guaranteed Time Large Program, IMEGIN, by fitting simultaneously a single Sérsic model on broadband images, from UV to millimeter (mm) wavelengths, using the multiband modelling code GALFITM. With the recently acquired NIKA2 1.2- and 2-mm observations, it is possible to extend such a morphological analysis to the mm regime and investigate the two-dimensional (2D) distribution (exponential, Gaussian) of the very cold dust (<15K). I will show preliminary results of the 2D large-scale distribution of stars and dust in spiral galaxies, how they relate to each other, and highlight how they differ from galaxy to galaxy.
