V4743 Sgr, a magnetic nova?

P. Zemko, M. Orio, K. Mukai +3

Two XMM Newton observations of Nova V4743 Sgr (Nova Sgr 2002) were performed shortly after it returned to quiescence, 2 and 3.5 years after the explosion. The X-ray light curves re…

Wavelet and R/S analysis of the X-ray flickering of cataclysmic variables

G. Anzolin, F. Tamburini, D. de Martino +1

Recently, wavelets and R/S analysis have been used as statistical tools to characterize the optical flickering of cataclysmic variables. Here we present the first comprehensive stu…

Method to measure off-axis displacements based on the analysis of the intensity distribution of a vortex beam

G. Anzolin, F. Tamburini, A. Bianchini +1

We study the properties of the Fraunhofer diffraction patterns produced by Gaussian beams crossing spiral phase plates. We show, both analytically and numerically, that off-axis di…

Analysis of the white--light flickering of the Intermediate Polar V709 Cas with wavelets and Hurst analysis

F. Tamburini, D. De Martino, A. Bianchini

We characterize the flickering observed in the optical lightcurve of the Intermediate Polar system V709 Cas by determining its position in the alpha-Sigma as in the Fritz and Bruch…

Optical vortices with starlight: Implications for ground-based stellar coronagraphy

F. Tamburini, G. Anzolin, G. Umbriaco +2

Using an l = 1 blazed fork-hologram at the focal plane of the Asiago 122 cm telescope, we obtained optical vortices from the stellar system Rasalgethi (alpha Herculis) and from the…

Overcoming the Rayleigh Criterion Limit with Optical Vortices

F. Tamburini, G. Anzolin, G. Umbriaco +2

We experimentally and numerically tested the separability of two independent equally-luminous monochromatic and white light sources at the diffraction limit, using Optical Vortices…
