    Toward an Understanding of the Seyfert Galaxy NGC 5252: A Spectroscopic Study
    We present long-slit spectra of the Seyfert 2 galaxy NGC 5252, covering the nucleus and part of the extranuclear emission-line region. All the regions sampled...

    Toward excluding a light Z<SUP>'</SUP> explanation of b →s ℓ<SUP>+</SUP>ℓ<SUP>-</SUP>
    The discrepancies between b →s ℓ +ℓ - data and the corresponding Standard Model predictions constitute one of the most significant hints for new physics...

    Toward measuring supermassive black hole masses with interferometric observations of the dust continuum
    This work focuses on active galactic nuclei (AGNs) and on the relation between the sizes of the hot dust continuum and the broad-line region (BLR). We find that...

    Toward the uplink correction: application of adaptive optics techniques on free-space optical communications through the atmosphere
    The optical ground station (OGS), installed in the Teide Observatory since 1995, was built as part of ESA efforts in the research field of satellite optical...

    Towards a dynamical mass of the ultraluminous X-ray source NGC 5408 X-1
    We obtained multi-epoch Very Large Telescope optical spectroscopic data in 2011 and 2012 on the ultraluminous X-ray source NGC 5408 X-1. We confirm that the He...

    Towards a more complete sample of binary central stars of planetary nebulae with Gaia
    Context. Many if not most planetary nebulae (PNe) are now thought to be the outcome of binary evolutionary scenarios. However, only a few percent of the PNe in...

    Towards a new classification of galaxies: principal component analysis of CALIFA circular velocity curves
    We present a galaxy classification system for 238 (E1-Sdm) CALIFA (Calar Alto Legacy Integral Field Area) galaxies based on the shapes and amplitudes of their...

    Towards a Unified View of Inhomogeneous Stellar Winds in Isolated Supergiant Stars and Supergiant High Mass X-Ray Binaries
    Massive stars, at least ˜10 times more massive than the Sun, have two key properties that make them the main drivers of evolution of star clusters, galaxies...

    Towards an improvement in the spectral description of central stars of planetary nebulae
    Context. There are more than 3000 known Galactic planetary nebulae, but only 492 central stars of Galactic planetary nebulae (CSPN) have known spectral types...
