Abstract In this work we will develop detailed comparisons between the central regions of the milky way galaxy and its morphological twins (SABbc and SBbc). The project of observations of the Milky Way morphological twins will continue, focusing on the study of their nuclei, whose sample was obtained from the data of the Diving3D survey (Deep IFS View of Nuclei of Galaxies). This survey has the goal of studying the central regions of all galaxies in the southern hemisphere with B magnitude lower than 12, using data cubes obtained with the IFU (Integral Field Unit) of GMOS (Gemini Multi-Object Spectrograph) from the Gemini-South and Gemini-North telescopes, complementing with data of other spectral bands. The goals are to study the emission properties of the nuclear and circumnuclear regions (with the average full width half-maximum of the point spread function being 0".63), the kinematic properties of the gas and stellar components, and the stellar archaeology, in order to infer the common characteristics of the sample and the diversity of the phenomena as they appear in the milky way analogues. The comparison, within a sample of a given morphological type, is important in order to determine the evolution of nuclei of galaxies and establish possible relations between different parameters. Until now, 10 galaxies were analyzed and we have 5 galaxies to analyze to complete this sample of the survey. However, in order to determine the influence of the bar in the context of the nuclear region, 8 non-barred galaxies (SAbc) of the DIVING3D survey will also be analyzed, totalizing 23 galaxies in the sample. With that, it will be possible to make a more robust statistical analysis and more concrete comparisons, in order to establish the evolution of those galactic nuclei and their similarities and differences, with high spatial resolution data and high signal-to-noise spectra.
