Description
We present positions and magnitudes of stars and star clusters in a 1° × 1° area centered on M33. The survey is based on deep archival ground-based images using the MegaPrime camera on the 3.6m Canada-France-Hawaii telescope. We provide u′, g′, r′, i′, z′ magnitudes by performing standard profile-fitting photometry of these images and apply image classification algorithms such as SExtractor. We also present a catalog of extended sources by applying visual-inspection classification. This complete catalog provides promising targets for deep photometry with HST and for high-resolution spectroscopy to study the structure and star-formation history of the disk and halo of M33.

    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
