An iterative algorithm for the square-root Lasso
Patrizia Boccacci, Christine De Mol, Ignace Loris
In the framework of sparsity-enforcing regularisation for linear inverse problems, we consider the minimisation of a square-root Lasso cost function. To solve this problem we devis…
Commissioning and improvements of the instrumentation and launch of the scientific exploitation of OARPAF, the Regional Astronomical Observatory of the Antola Park
Davide Ricci, Silvano Tosi, Lorenzo Cabona +17
The \oarpaf telescope is an -diameter optical telescope installed in the Antola Mount Regional Reserve, in Northern Italy. This work presents the results of the character…
A method for space-variant deblurring with application to adaptive optics imaging in astronomy
Andrea La Camera, Laura Schreiber, Emiliano Diolaiti +4
Images from adaptive optics systems are generally affected by significant distortions of the point spread function (PSF) across the field of view, depending on the position of natu…
A blind deconvolution method for ground based telescopes and Fizeau interferometers
M. Prato, A. La Camera, S. Bonettini +3
In the case of ground-based telescopes equipped with adaptive optics systems, the point spread function (PSF) is only poorly known or completely unknown. Moreover, an accurate mode…
Efficient deconvolution methods for astronomical imaging: algorithms and IDL-GPU codes
M. Prato, R. Cavicchioli, L. Zanni +2
The Richardson-Lucy method is the most popular deconvolution method in astronomy because it preserves the number of counts and the non-negativity of the original object. Regulariza…
Image reconstruction for observations with a high dynamic range: LINC-NIRVANA simulations of a stellar jet
Andrea La Camera, Simone Antoniucci, Mario Bertero +3
We report the results of a simulation and reconstruction of observations of a young stellar object (YSO) jet with the LINC-NIRVANA (LN) interferometric instrument, which will be mo…
