Standing oscillations in a resonant sunspot atmosphere captured by integral field spectroscopy
Glen Chambers, David B. Jess, Shahin Jafarzadeh +8
The solar atmosphere is replete with magnetohydrodynamic wave activity, with magnetic structures such as sunspots channelling wave energy flux efficiently into the outer atmosphere…
Magnetically Structured Oscillatory Power Along an Active-Region Transect in Near-UV Sunrise-III/SUSI Spectroscopy
Shahin Jafarzadeh, David B. Jess, Marco Stangalini +33
We present a multi-line characterisation of how oscillatory power is organised across distinct magnetic environments in an active region using seeing-free, stratospheric near-ultra…
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…
Adaptive multi-line fitting for stable line-core intensity and Doppler velocity
Shahin Jafarzadeh, David B. Jess, Marco Stangalini +5
Next-generation solar spectrographs increasingly record dense wavelength windows in which tens to hundreds of spectral lines are sampled at each spatial location and time step. Thi…
