Abstract

In hierarchical models of galaxy formation and evolution, galaxies grow through gas accretion and merger events. The tidal debris produced during these mergers serves as a fossil record of a galaxy’s assembly history, with characteristics that depend on the nature of the merger. Exploring these faint Low Surface Brightness (LSB) structures around galaxies of varying masses and environments is essential to fully understanding galactic evolution. Advances in dedicated instruments and data reduction pipelines from past, ongoing, and future surveys have significantly expanded our ability to explore the LSB Universe. In this talk, I will discuss how LSB features can be leveraged to investigate galactic growth, using deep imaging data from the Canada-France-Hawaii Telescope (CFHT) and ESA ’s Euclid space telescope, combined with an innovative online annotation tool.
