    Numerical Modeling of Magnetohydrodynamic Wave Propagation and Refraction in Sunspots
    We present numerical simulations of magnetoacoustic wave propagation from the photosphere to the low chromosphere in a magnetic sunspot-like structure. A thick...

    Numerical Simulations of Conversion to Alfvén Waves in Sunspots
    We study the conversion of fast magnetoacoustic waves to Alfvén waves by means of 2.5D numerical simulations in a sunspot-like magnetic configuration. A fast...

    Observation and Modeling of Anomalous CN Polarization Profiles Produced by the Molecular Paschen-Back Effect in Sunspots
    We report novel spectropolarimetric observations of sunspots carried out with the Tenerife Infrared Polarimeter in a near-IR spectral region around 15410 Å...

    Observation and Modeling of the Circular Polarization of the Cr I Magnetic-field-induced Transition at 533.03 nm
    We study the circular polarization of the magnetic-field-induced transition (MIT) between the 3d 5( 6 S)4d 7 D 2 and 3d 5( 6 S)4p 7 P 4° states of Cr I at 533...

    Observation of Convective Collapse and Upward-moving Shocks in the Quiet Sun
    We present spectropolarimetric evidence of convective collapse and destruction of magnetic flux by upward-moving fronts in the quiet Sun. The observational...

    Observation of Gamma Rays from the Galactic Center with the MAGIC Telescope
    Recently, the Galactic center has been reported to be a source of very high energy (VHE) γ-rays by the CANGAROO, VERITAS, and HESS experiments. The energy...
