    The use of sodium layer density anisotropies to fully measure the atmospheric turbulence, including tip-tilt, focus, and higher order aberrations
    It is well known that Adaptive Optics (AO) observations do require the availability of natural stars (beside laser guide stars - LGSs) to obtain the tip-tilt...

    The Use of Spectro-Polarimetric Measurements to determine the Plasma Heating
    We present the possible use of spectro-polarimetric measurements on a set of data recorded with La Palma Stokes Polarimeter attached to the Swedish Vacuum Solar...

    The use of turbulence-profile measurements to predict the performance of adaptive optics systems
    It is planned to include adaptive optics as an integral part of the 10-m Gran Telescopio Canarias. Preliminary scientific requirements have been drawn up, and...

    The UV - optical - near-IR emission of BL Lacertae objects.
    Results from UV, optical and near-IR simultaneous observations for 11 BL Lac objects are reported. The authors find that for all but one source the spectral...

    The Uv Spectral Window: New Means To Constrain The Stellar Populations Of Early-Type Galaxies
    We discuss the possibilities of exploiting the UV spectral using the J-PAS survey to disentangle young contributions from apparently old galaxies. We show that...

    The Value of the Fine Structure Constant Over Cosmological Times
    The optical spectra of objects classified as QSOs in the SDSS DR6 are analyzed with the aim of determining the value of the fine structure constant in the past...
