Descripción
Mapping the low surface brightness (μ >28 mag arcsec^{-2}) structures of the galaxies opens the possibility of testing our current ΛCDM galaxy formation model. At these surface brightness values the accretion history of the galaxies should clearly reveal. We present here two undergoing projects conducted at the IAC whose aim is to explore the lowest surface brightness regions of nearby galaxies using ultra-deep imaging. The first one is the Stripe82 IAC Legacy Project, 270 square degrees based on the SDSS Stripe82 data reaching down to 28.5 mag arcsec^{-2}. The second is an overwhelmingly deep imaging of a nearby galaxy, UGC 00180, taken with the 10.4m GTC telescope and showing galaxy details down to 31.5 mag arcsec^{-2}.
