    The continuum intensity-magnetic field relation in sunspot umbrae
    We describe the work carried out to obtain observational evidence of a local relation between the temperature and the magnetic field in different regions of...
  • Publication
    The contribution of N-rich stars to the Galactic stellar halo using APOGEE red giants
    The contribution of dissolved globular clusters (GCs) to the stellar content of the Galactic halo is a key constraint on models for GC formation and destruction...
  • Publication
    The Contribution of the Kinematic Sunyaev-Zel'dovich Effect from the Warm-Hot Intergalactic Medium to the Five-Year Wilkinson Microwave Anisotropy Probe Data
    We study the contribution of the kinematic Sunyaev-Zel'dovich (kSZ) effect, generated by the warm-hot intergalactic medium, to the cosmic microwave background...

    The Cool Supergiant Population of the Massive Young Star Cluster RSGC1
    We present new high-resolution near-IR spectroscopy and OH maser observations to investigate the population of cool luminous stars of the young massive Galactic...

    The Cool Surge Following Flux Emergence in a Radiation-MHD Experiment
    Cool and dense ejections, typically Hα surges, often appear alongside EUV or X-ray coronal jets as a result of the emergence of magnetized plasma from the solar...

    The core-halo structure of IC 418
    Deep spectra of the planetary nebula IC 418 were obtained in the wavelength range 4190-5850 A. The data made it possible to map an extended halo about the...
