    What do galaxies look like beyond 31 mag/arcsec2?
    Detection of optical surface brightness structures with magnitudes fainter than 30 mag/arcsec2 has remained elusive in current photometric deep surveys. We are...
  • Publication
    What drives the variance of galaxy spectra?
    We present a study aimed at understanding the physical phenomena underlying the formation and evolution of galaxies following a data-driven analysis of...
