Aims. We seek to determine to what extent the problem of forward fitting visibilities measured
by the Spectrometer/Telescope Imaging X-rays (STIX) on board Solar Orbiter becomes more …

CLEAN is an iterative deconvolution method for radio and hard-X-ray solar imaging. In a
specific step of its pipeline, CLEAN requires the convolution between an idealized version of …

In this work we deal with parametric inverse problems, which consist in recovering a finite
number of parameters describing the structure of an unknown object, from indirect …

Context. The generation of spatially resolved count spectra and of cubes of count maps at
different energies via imaging spectroscopy is one of the main goals of solar hard X-ray …

Aims. This study is aimed at providing the first demonstration of STIX Fourier-transform X-ray
imaging using semi-calibrated (amplitude-only) visibility data acquired during Solar Orbiter's …

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 …

AI-FLARES (Artificial Intelligence for the Analysis of Solar Flares Data) is a research project
funded by the Agenzia Spaziale Italiana and by the Istituto Nazionale di Astrofisica within the …

Abstract The Spectrometer/Telescope for Imaging X-rays (STIX) is one of the ten instruments
on board the scientific payload of ESA's Solar Orbiter mission. STIX provides hard X-ray …

This paper aims to provide an overview of variably scaled kernels introduced in [10] and
review their applications highlighting the contribution by Stefano De Marchi and his …
