Multiwavelegths analysis of galaxies’morphologies and their internal structure
We will present preliminary results obtained analysing a sample of bright galaxies in the AEGIS field with GALFITM ( a multiwavelength implementation of GALFIT – to perform parametric fits of galaxy images), using the 54 narrow and 4 broad band miniJPAS images. GALFITM allows us to decompose the galaxy light into its different components, such as bulge, disk and AGN, when present. We study the wavelength variation of the recovered morphological parameters, especially the Sersic index and effective radius, for different galaxy morphologies and sub-components. For a subsample of galaxies we investigate the radial variation of galaxies’ properties, such as stellar mass density and specific star formation rate, for different Sersic indexes of the bulge. Finally, we are now exploring the multi wavelengths residual images.
