Expanding magnetic canopy structure and parasitic polarities in a quiet-Sun network element observed by Sunrise III/SCIP
Ryan J. Campbell, Carlos Quintero Noda, Mihalis Mathioudakis +44
We present high-resolution multi-line spectropolarimetric observations of a quiet-Sun network element obtained with the {\sc Sunrise~iii} Chromospheric Infrared SpectroPolarimeter.…
Horizontal Magnetic Fields Dominate the Quiet Sun Internetwork in Sunrise III Observations. Evidence from Traditional and Transformer-Based Inversions
Ryan J. Campbell, Carlos Quintero Noda, Manuel Collados +41
The relative prevalence of horizontal and vertical magnetic fields in the quiet-Sun internetwork remains debated, owing to the weak linear polarisation signals that make the inferr…
DKIST Unveils Four-Lobed Stokes U Profiles in a Magnetically Complex Sunspot Penumbra
Ryan James Campbell, Sarah Jaeggli
We present DKIST spectropolarimetric observations of a sunspot penumbra revealing spatially coherent four-lobed Stokes U profiles that persist after polarimetric crosstalk correcti…
The Influence of Opacity on Inferred MHD Wave Signatures in the Lower Solar Atmosphere
Samuel J. Skirvin, Samuel D. T. Grant, David B. Jess +8
Magnetohydrodynamic wave activity in small-scale magnetic structures, such as solar pores, provides key insights into energy transport in the lower solar atmosphere. This study pre…
Small-scale bright point characteristics at high-resolution with the Daniel K. Inouye Solar Telescope
Peter H. Keys, Ryan J. Campbell, Dylan K. J. Magill +9
Bright points (BPs) are small-scale, dynamic features that are ubiquitous across the solar disc and are often associated with the underlying magnetic field. Using broadband photosp…
Transformers for Stratified Spectropolarimetric Inversion: Proof of Concept
Ryan James Campbell, Mihalis Mathioudakis, Carlos Quintero Noda
Solar spectropolarimetric inversion -- inferring atmospheric conditions from the Stokes vector -- is a key diagnostic tool for understanding solar magnetism, but traditional invers…
