CLEAN and multi-scale CLEAN for STIX in Solar Orbiter
Miriana Catalano, Anna Volpara, Paolo Massa +2
CLEAN is a well-established deconvolution approach to Fourier imaging at both radio wavelwengths and hard X-ray energies. However, specifically for hard X-ray imaging, CLEAN suffer…
Variably Scaled Kernels for the regularized solution of the parametric Fourier imaging problem
Anna Volpara, Alessandro Lupoli, Emma Perracchione
We address the problem of approximating parametric Fourier imaging problems via interpolation/ extrapolation algorithms that impose smoothing constraints across contiguous values o…
Solar flares as electron accelerators: toward a resolution of the acceleration efficiency issue
Anna Volpara, Paolo Massa, Michele Piana +2
A major open issue concerning the active Sun is the effectiveness with which magnetic reconnection accelerates electrons in flares. A paper published by {\em{Nature}} in 2022 used…
Using the STIX background detector as a proxy for GOES
Muriel Zoë Stiefel, Matej Kuhar, Olivier Limousin +4
Context. The Spectrometer/Telescope for Imaging X-Rays (STIX) onboard Solar Orbiter was designed to observe solar flares in the X-ray range of 4-150 keV, providing spectral, tempor…
