Deep imaging of the most massive galaxies of the nearby Universe
Abstract
Taking advantage of deep photometric data from HST, we analyze the z < 0.5 massive galaxies obtained in the H- and I-bands, in order to disentangle the several components that might constitute most massive galaxies in our Universe. We perform single and double-Sérsic analysis for our sample of 17 galaxies. From our photometric analysis, we notice that Sérsic index values are not a good representation of a galaxy's morphological type and find no trend between B/T and redshift. We detect within our sample two late-type galaxies with sizes smaller than expected. Additionally, our set of simulations shows that the apparent magnitudes and Sérsic index are the key parameters to a good recovery of the structural parameters.
