Descripción
Recently a tight correlation between the bulge velocity dispersion and the galaxy circular velocity has been found for a sample of spiral galaxies (Ferrarese 2002). Since bulge velocity dispersion and circular velocity are related to the masses of the central black hole and dark matter halo respectively, the correlation between velocity dispersion and circular velocity is equivalent to one between the mass of super-massive black hole and dark halo. We explore this correlation by using velocity dispersions and circular velocities derived from stellar and ionized-gas kinematics we measured for a sample of 17 intermediate-to-late type spiral galaxies. We plan now to apply the same analysis to a sample of low surface brightness galaxies.

    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
