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…
Study of an active region prominence using spectropolarimetric data in the He I D3 multiplet
S. Esteban Pozuelo, A. Asensio Ramos, J. Trujillo Bueno +3
Prominences are cool overdensities of plasma supported by magnetic fields that levitate in the solar corona. The physical characterization of these structures is key for understand…
Properties of sunspot light bridges on a geometric height scale
S. Esteban Pozuelo, A. Asensio Ramos, C. J. Díaz Baso +1
Investigating light bridges (LBs) helps us comprehend key aspects of sunspots. However, few studies have analyzed the properties of LBs in terms of the geometric height, which is a…
Estimating the longitudinal magnetic field in the chromosphere of quiet-Sun magnetic concentrations
S. Esteban Pozuelo, A. Asensio Ramos, J. de la Cruz Rodríguez +2
Details of the magnetic field in the quiet Sun chromosphere are key to our understanding of essential aspects of the solar atmosphere. We aim to determine the longitudinal magnetic…
Transverse oscillations in 3D along Ca II K bright fibrils in the solar chromosphere
Sepideh Kianfar, Jorrit Leenaarts, Sara Esteban Pozuelo +3
Fibrils in the solar chromosphere carry transverse oscillations as determined from non-spectroscopic imaging data. They are estimated to carry an energy flux of several $\mathrm{kW…
Accelerating non-LTE synthesis and inversions with graph networks
A. Vicente Arévalo, A. Asensio Ramos, S. Esteban Pozuelo
The computational cost of fast non-LTE synthesis is one of the challenges that limits the development of 2D and 3D inversion codes. It also makes the interpretation of observations…
Emergence of internetwork magnetic fields through the solar atmosphere
Milan Gošić, Bart De Pontieu, Luis R. Bellot Rubio +2
Internetwork (IN) magnetic fields are highly dynamic, short-lived magnetic structures that populate the interior of supergranular cells. Since they emerge all over the Sun, these s…
The dark side of penumbral microjets: Observations in Hα
D. Buehler, S. Esteban Pozuelo, J. de la Cruz Rodriguez +1
We present data of 10 penumbral microjets (PMJs) observed in Hα, Ca II 8542 Å, and Fe I 6302 Åline pair with the Swedish 1 m Solar Telescope (SST) with CRISP and Ca II K with SST/C…
Observationally based models of penumbral microjets
S. Esteban Pozuelo, J. de la Cruz Rodriguez, A. Drews +3
We study the polarization signals and physical parameters of penumbral microjets (PMJs) by using high spatial resolution data taken in the Fe I 630 nm pair, Ca II 854.2 nm and Ca I…
Chromospheric observations and magnetic configuration of a supergranular structure
Carolina Robustini, Sara Esteban Pozuelo, Jorrit Leenaarts +1
Unipolar magnetic regions are often associated with supergranular cells. The chromosphere above these regions is regulated by the magnetic field, but the field structure is poorly…
Chromospheric heating due to cancellation of quiet Sun internetwork fields
Milan Gošić, Jaime de la Cruz Rodríguez, Bart De Pontieu +5
The heating of the solar chromosphere remains one of the most important questions in solar physics. Our current understanding is that small-scale internetwork (IN) magnetic fields…
A study on Ca II 854.2 nm emission in a sunspot umbra using a thin cloud model
H. Hamedivafa, M. Sobotka, L. Bellot Rubio +1
In the present work, we introduce and explain a method of solution of the radiative transfer equation based on a thin cloud model. The efficiency of this method to retrieve dynamic…
