We study the pitch angles of spiral arms and the frequency and dimensions of inner and outer rings as a function of disk parameters and the amplitude of non-axisymmetries in the S 4G survey. We provide observational evidence for i) the role of strong bars in ring formation/evolution and ii) the dependence between bar and spiral strengths. Yet, the

The low surface brightness (LSB) universe is one of the last frontiers in observational astronomy. However, uncovering the information contained in ultra-deep imaging is technically challenging. In this contribution, we present one of the fundamental tools of LSB astronomers: correcting for the extended Point-Spread Function (PSF), which is

The low surface brightness Universe is one of the latest frontier in observational Astronomy. However, uncovering the precious information contained in ultra-deep imaging is technically challenging. In this contribution, we will present one of the fundamental tools in the toolbox of low surface brightness astronomers: the extended Point Spread

Upcoming deep surveys (e.g. LSST, JWST, EUCLID) will provide high quality imaging at unprecedentedly high red shifts, allowing the study of galaxy morphology at different cosmic times. The processing of such data will be necessarily automatized due to its enormous volume. Deep Learning has proven to be a powerful tool in these situations. Previous
