The Ca IR triplet lines are a good candidate for observing chromospheric magnetic fields. Simulations of the lines in the high-beta regime, spectropolarimetric...

The CAFADIS camera is a new wavefront sensor (WFS) patented by the Universidad de La Laguna. CAFADIS is a system based on the concept of plenoptic camera...

Based on O II recombination lines we present a new calibration (called O II_{RL}) of Pagel's O_{23} indicator to determine the O/H abundance ratio in...

We report on the status of the Canarias InfraRed Camera Experiment (CIRCE), a near-infrared visitor instrument for the 10.4 meter Gran Telescopio Canarias (GTC)...

We present the current status of the Canarias InfraRed Camera Experiment (CIRCE) an all-reflective near-IR, imager, spectrograph, and polarimeter for the 10.4...

The development of astrophysical observatories in the Canary Islands by the European community is discussed. Consideration is given to principal astronomical...

An analysis of high-resolution Stokes observations of two light bridges in the active region NOAA 8990 is presented. The observations were recorded with the La...

Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of...
