An Unusual Velocity Field in a Sunspot Penumbra
H. Balthasar, C. Denker, A. Diercke +6
The photospheric Evershed flow is normally oriented radially outward, yet sometimes opposite velocities are observed not only in the chromosphere but also in the photospheric layer…
Velocity field of an Active Region filament from GRIS IR He I and IRIS UV observations
M. Murabito, V. Andretta, S. Parenti +4
Plasma flow measurements in solar active region filaments are rare, particularly in the infrared and ultraviolet ranges that probe the chromosphere and transition region. In additi…
On the center-to-limb variations of the He I 10830 Å triplet
A. G. M. Pietrow, C. Kuckein, M. Verma +4
We present high-resolution spectroscopic observations of the quiet-Sun center-to-limb variations (CLV) of the He I triplet at 10830 Å and the nearby Si I 10827 Å line, observed wit…
Deep learning image burst stacking to reconstruct high-resolution ground-based solar observations
Christoph Schirninger, Robert Jarolim, Astrid M. Veronig +1
Large aperture ground based solar telescopes allow the solar atmosphere to be resolved in unprecedented detail. However, observations are limited by Earths turbulent atmosphere, re…
Chromospheric velocities in an M3.2 flare using He I 1083.0 nm and Ca II 854.2 nm
C. Kuckein, M. Collados, A. Asensio Ramos +6
We study the chromospheric LOS velocities during the GOES M3.2 flare (SOL2013-05-17T08:43) using simultaneous spectroscopic data of the He I 1083.0 nm triplet and Ca II 854.2 nm li…
torchmfbd: a flexible multi-object multi-frame blind deconvolution code
A. Asensio Ramos, C. Díaz Baso, C. Kuckein +2
Post-facto image restoration techniques are essential for improving the quality of ground-based astronomical observations, which are affected by atmospheric turbulence. Multi-objec…
Fine-scale opposite-polarity magnetic fields in a solar plage revealed by integral field spectropolarimetry
G. Liu, I. Milić, J. S. Castellanos Duran +3
Plages are small concentrations of strong, nearly vertical magnetic fields in the solar photosphere that expand with height. A high spatial and spectral resolution that can resolve…
