    Explanation of the linear polarization of the Ca II IR triplet: zero-field dichroism in the solar chromosphere
    The linear polarization produced by scattering processes in the spectral lines of the IR triplet of Ca II can be observed near the edge of the solar disk. The...

    Far infrared detected Lyman break galaxies at z ~ 3: Dust attenuation and dust correction factors at high redshift.
    Lyman break galaxies (LBGs) represent one of the kinds of star-forming galaxies that are found in the high-redshift universe. The detection of LBGs in the FIR...
