Compressed sensing and Sequential Monte Carlo for solar hard X-ray imaging
Anna Maria Massone, Federica Sciacchitano, Michele Piana +1
We describe two inversion methods for the reconstruction of hard X-ray solar images. The methods are tested against experimental visibilities recorded by the Reuven Ramaty High Ene…
Bayesian Multi--Dipole Modeling in the Frequency Domain
Gianvittorio Luria, Dunja Duran, Elisa Visani +6
Background: Magneto- and Electro-encephalography record the electromagnetic field generated by neural currents with high temporal frequency and good spatial resolution, and are the…
Sparse Bayesian Imaging of Solar Flares
Federica Sciacchitano, Silvio Lugaro, Alberto Sorrentino
We consider imaging of solar flares from NASA RHESSI data as a parametric imaging problem, where flares are represented as a finite collection of geometric shapes. We set up a Baye…
Identification of multiple hard X-ray sources in solar flares: A Bayesian analysis of the February 20 2002 event
Federica Sciacchitano, Alberto Sorrentino, A Gordon Emslie +2
The hard X-ray emission in a solar flare is typically characterized by a number of discrete sources, each with its own spectral, temporal, and spatial variability. Establishing the…
