On-Sky Single-photon Time resolution of 35 ps with White Rabbit synchronization: towards the measurement of the size of a White Dwarf star
F. Izraelevitch-Patitucci, S. Tolilla, I. Ellafi +7
The IC4Stars (Intensity Correlation for Stars) project aims to measure the diameter of the white dwarf star Sirius B, using Intensity Interferometry. In this work we present our la…
Stellar intensity interferometry in the photon-counting regime
William Guerin, Mathilde Hugbart, Sarah Tolila +5
Stellar intensity interferometry consists in measuring the correlation of the light intensity fluctuations at two telescopes observing the same star. The amplitude of the correlati…
Optical pattern formation in self-focusing and self-defocusing diffractively thick media
G. Labeyrie, I. KreÅ¡iÄ, R. Kaiser +1
Cold atomic clouds constitute highly resonant nonlinear optical media, whose refractive index can be easily tuned via the light frequency. When subjected to a retro-reflected laser…
Increasing the sensitivity of stellar intensity interferometry with optical telescopes: First laboratory test of spectral multiplexing
S Tolila, G Labeyrie, R Kaiser +2
We present a preliminary laboratory test of a setup designed to measure Hanbury Brown and Twiss-type intensity correlations from a chaotic light source using five spectral channels…
