High Resolution Spectropolarimetry and Magnetography
From an observational point of view, magnetic field leaves its imprint, via Zeeman effect, on spectral line splitting and the induced wavelength dependence of...
High Resolution Spectropolarimetry of Penumbral Formation with IBIS
We present the results of first spectropolarimetric observations made with the Interferometric Bidimensional Spectrometer (IBIS) at the NSO/Dunn Solar Telescope...
High Resolution Stimulated Raman Spectroscopy of Carbon Tetrafluoride CF_4
The spectra of the ν_1, ν_2 and 2ν_2 bands were obtained with a quasi-cw stimulated Raman spectrometer. In this technique, two laser beams are focused...
High spatial resolution and high contrast optical speckle imaging with FASTCAM at the ORM
In this paper, we present an original observational approach, which combines, for the first time, traditional speckle imaging with image post-processing to...
Physical processes in the Sun give rise to an ample variety of structures on different spatial scales that in many cases are very small, with sizes probably...
