We present an investigation of a single sunspot observed in the neutral Fe line at 1089.6 nm with the Tenerife Infrared Polarimeter at the Vacuum Tower...
SOPHISM: An End-to-end Software Instrument Simulator
We present a software simulator for the modeling of astronomical instrumentation, which includes platform effects and software processing. It is an end-to-end...
Spatial deconvolution of spectropolarimetric data: an application to quiet Sun magnetic elements
Context. One of the difficulties in extracting reliable information about the thermodynamical and magnetic properties of solar plasmas from spectropolarimetric...
Spectral signature of uncombed penumbral magnetic fields
The uncombed penumbral model proposed by Solanki & Montavon (cite{sol93a}) is used to understand some recent observational results found in penumbrae. This...
Spectral signature of uncombed penumbral magnetic fields. Comment
The conservation of magnetic flux demands a magnetic field fine structure as small as 15 km to explain the net circular polarization observed in penumbrae...
Spectral signature of uncombed penumbral magnetic fields. Reply
A combination of two penumbral models similar to those used by Martínez Pillet (2000) is presented. One matches the observed rms fluctuations perfectly while...
Spectral study of the diffuse synchrotron source in the galaxy cluster Abell 523
The galaxy cluster Abell 523 (A523) hosts an extended diffuse synchrotron source historically classified as a radio halo. Its radio power at 1.4 GHz makes it...
Spectro-Polarimetric Imaging Reveals Helical Magnetic Fields in Solar Prominence Feet
Solar prominences are clouds of cool plasma levitating above the solar surface and insulated from the million-degree corona by magnetic fields. They form in...
