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}.

    The TESS TTV Follow-up Program: Revealing Volatile-Rich Terrestrial Planets Around M Stars
    Models predict that water-rich planets may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Recent JWST observations of sub-Neptune sized planets orbiting nearby M dwarfs found atmospheres enriched in CH4, CO2 and H2O, but the enrichment mechanism is debated. To answer this question

    The instrumentation plan of the 10.4m GTC telescope
    The 10.4m Gran Telescopio Canarias (GTC) was designed to be a versatile telescope, able to serve a wide scientific community. To this aim, various focal stations have been equipped, including a Cassegrain, two Nasmyth foci, and four folded-Cassegrain stations. This allows an ambitious instrumentation plan to be developed. We present the latest

    Design and fabrication of fold mirror (M3) system for New Robotic Telescope
    The New Robotic Telescope (NRT) is an autonomous telescope that can operate multiple instruments at the Cassegrain focal station and the straight-through port. The optical beam is directed to the ports by a fold mirror subsystem in the focal station assembly. The fold mirror is elliptical in shape, manufactured by Instituto Nazionale di Astrofisica
