A novel approach to identify resonant MHD wave modes in solar pores and sunspot umbrae: analysis
M. Stangalini, D. B. Jess, G. Verth +12
The umbral regions of sunspots and pores in the solar photosphere are generally dominated by ~mHz oscillations, which are due to -modes penetrating the magnetic region. In th…
XAO-assisted coronagraphy with SHARK NIR: from simulations to laboratory tests
Gabriele Umbriaco, Elena Carolo, Daniele Vassallo +22
Several Extreme Adaptive Optics (XAO) systems dedicated to the detection and characterisation of the exoplanets are currently in operation for 8-10 meter class telescopes. Coronagr…
Long-term optical monitoring of the solar atmosphere in Italy
S. L. Guglielmino, I. Ermolli, P. Romano +8
Probably, the long-term monitoring of the solar atmosphere started in Italy with the first telescopic observations of the Sun made by Galileo Galilei in the early $17^{\mathrm{th}}…
Recurrence quantification analysis as a post-processing technique in adaptive optics high-contrast imaging
M. Stangalini, G. Li Causi, F. Pedichini +8
In this work we explore the possibility of using Recurrence Quantification Analysis (RQA) in astronomical high-contrast imaging to statistically discriminate the signal of faint ob…
Speckle statistics in adaptive optics images at visible wavelengths
Marco Stangalini, Fernando Pedichini, Enrico Pinna +11
Residual speckles in adaptive optics (AO) images represent a well-known limitation on the achievement of the contrast needed for faint source detection. Speckles in AO imagery can…
Data processing on simulated data for SHARK-NIR
E. Carolo, D. Vassallo, J. Farinato +22
A robust post processing technique is mandatory to analyse the coronagraphic high contrast imaging data. Angular Differential Imaging (ADI) and Principal Component Analysis (PCA) a…
