    High-Precision Near-Infrared Photometry of a Large Sample of Bright Stars Visible from the Northern Hemisphere
    We present the results of 8 yr of infrared photometric monitoring of a large sample of stars visible from Teide Observatory (Tenerife, Canary Islands). The...
  • Publication
    High-resolution infrared spectroscopy as a tool to detect false positives of transit search programs
    Context. Transit search programs such as CoRoT and Kepler now have the capability of detecting planets as small as the Earth. The detection of these planets...

    High-resolution spectroscopy of Boyajian's star during optical dimming events
    Boyajian's star is an apparently normal main-sequence F-type star with a very unusual light curve. The dipping activity of the star, discovered during the...

    High-z Sudoku: a diagnostic tool for identifying robust (sub)mm redshifts
    We present methods to (i) graphically identify robust redshifts using emission lines in the (sub)mm regime, (ii) evaluate the capabilities of different (sub)mm...

    Higher order Hamiltonian Monte Carlo sampling for cosmological large-scale structure analysis
    We investigate higher order symplectic integration strategies within Bayesian cosmic density field reconstruction methods. In particular, we study the fourth...

    Hints of a close outer companion to the ultra-hot Jupiter TOI-2109 b
    Context. Hot Jupiters (HJs) with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their...

    Holographic imaging of crowded fields: high angular resolution imaging with excellent quality at very low cost
    We present a method for speckle holography that is optimized for crowded fields. Its two key features are an iterative improvement of the instantaneous point...

    Horizontal flow fields in and around a small active region. The transition period between flux emergence and decay
    Context. The solar magnetic field is responsible for all aspects of solar activity. Thus, emergence of magnetic flux at the surface is the first manifestation...

    HORuS transmission spectroscopy and revised planetary parameters of KELT-7 b
    We report on the high-resolution spectroscopic observations of two planetary transits of the hot Jupiter KELT-7b (M p = 1.28 ± 0.17M Jup, T eq = 2028 K)...
