  • Cool stars with hot companions in the Small Magellanic Cloud

    Most massive stars are born in binary systems, with 70% expected to interact with a companion within their lifetimes. The consequences of these interactions for subsequent evolutionary stages and for the endpoints of stellar evolution are still not well understood, particularly for the red supergiant (RSG) phase: the final evolutionary stage before

  • A high spectral resolution catalog of emission lines in the visible spectrum of comet C/2020 F3 (NEOWISE)

    Comets are primitive bodies left over from the formation of the Solar System. Formed at large distance from the Sun, comets have been preserved at low temperatures since their birth. Therefore, the study of comets offers a unique opportunity to investigate the physical and chemical processes that occurred during the early stages of the formation

  • Identifying the fingerprints of r-process heavy metals in a short GRB

    The afterglow of some short GRBs displays a late-time rebrightening, visible in the near-infrared a few days after the burst. This late-time bump could be explained as kilonova emission, providing a direct link to neutron star mergers, and a compelling proof for the synthesis of heavy nuclei through the rapid neutron capture process (r-process). We

  • CO kinematics unveil outflows plausibly driven by a young jet in the gigahertz peaked radio core of NGC 6328

    We report the detection of outflowing molecular gas in the center of the nearby (z = 0.014) massive radio galaxy NGC 6328. The radio core of the galaxy, PKS B1718-649, is identified as a gigahertz peaked spectrum source with a compact (2 pc) double radio lobe morphology. We used ALMA CO(2-1) and CO(3-2) observations at 100 pc resolution to study

  • A high-spectral-resolution catalog of emission lines in the visible spectrum of comet C/2020 F3 (NEOWISE)

    Aims: Comet C/2020 F3 (NEOWISE) is considered to be the brightest comet observed in the northern hemisphere since the passage of comet C/1995 O1 (Hale-Bopp) in 1997. Since the study of comets offers a unique opportunity to investigate the early stages of the formation and evolution of our Sun and the Solar System, we obtained high-resolution

  • APOGEE Chemical Abundance Patterns of the Massive Milky Way Satellites

    The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey has obtained high-resolution spectra for thousands of red giant stars distributed among the massive satellite galaxies of the Milky Way (MW): the Large and Small Magellanic Clouds (LMC/SMC), the Sagittarius Dwarf Galaxy (Sgr), Fornax (Fnx), and the now fully
