We present a discussion of efforts to obtain external validation of the estimated atmospheric parameters (Teff, log g, [Fe/H]) obtained from medium-resolution...

This communication reviews some of the most challenging topics in high-resolution ground-based Solar Physics. The most powerful European facilities are...

We present first comparisons between high resolution observations of the quiet photosphere, obtained with the Interferometric BIdimensional Spectrometer (IBIS)...

High resolution observations of a very quiet region of the solar surface have been obtained with IBIS (Interferometric BIdimensional Spectrometer) in the non...

Lucky Imaging combined with a low order adaptive optics system has given the highest resolution images ever taken in the visible or near infrared of faint...

A sample of active galaxies and quasars was observed with a photon-counting detector (IPCS) working in time-resolved imaging mode. The observing and data...

Nuclear rings in barred spiral galaxies offer an opportunity to study starburst properties, as well as the evolution of star formation in the central regions of...

We analyze Atacama Large Millimeter Array (ALMA) observations of the CO(6-5) molecular line and the 432 μm continuum emission from the circumnuclear disk (CND)...
