    The upcoming spectroscopic powerhouses at the Isaac Newton Group of Telescopes
    The Isaac Newton Group of Telescopes is completing a strategic change for the scientific use of its two telescopes, the 4.2-m William Herschel Telescope (WHT)...

    The upgraded GREGOR infrared spectrograph
    For more than ten years, the GREGOR Infrared Spectrograph (GRIS) has been the main spectropolarimeter on the GREGOR telescope since its inauguration in 2012...
  • Publication
    The use of alternative energies for powering ELTs
    The use of alternative energies is becoming common in many places around the world. It is envisaged that most large projects will consider the use of...
  • Publication
    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...
  • Publication
    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...
