Description
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}.

    Co-phasing the distributed aperture of a Fizeau interferometer via photonic lanterns and machine learning
    The advantage of large optical telescopes from the ground for high-contrast direct imaging relies on achieving exquisite control of the incident optical wavefront. Since the exoplanet problem almost always has a bright star within a small field of view there are usually ample photons for measuring the atmospheric and telescopedistorted wavefront. A

    Unveiling Chiron, an odd ice ball, with Webb: Ice and Gas Phases Revealed
    We present unprecedented findings on (2060) Chiron using James Webb Space Telescope (JWST) NIRSpec imaging and spectroscopy from cycle 1 GTO program 1273. Our study (Pinilla-Alonso et al. 2024 A&A Letter) marks the first detection of carbon dioxide (CO 2) and methane (CH 4) active outgassing and coma emission at heliocentric distances of ~18 au

    Conceptual optical design of the infrared integral field spectropolarimeter for the European Solar Telescope
    The European Solar Telescope (EST), with its primary mirror of 4.2 diameter, will be the largest solar telescope available in Europe. EST will offer Integral Field Spectropolarimetry (IFS) by incorporating the EST spectropolariMeter Based on slicEr-mirrors for the near-infraRed (EMBER). This instrument is a high-resolution spectropolarimeter that
