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…

ESO White Paper on Intensity Interferometry: Cosmology, Fundamental Physics, Quantum Optics

Robin Kaiser, William Guerin, Farrokh Vakili +21

In this whitepaper, we outline how recent technological advances and ongoing developments open qualitatively new science opportunities in cosmology, fundamental physics, and quantu…

Stellar physics at sub-nanoradian angular resolution

P. Batista, J. Biteau, C. Carlile +36

Many stars -- if they could be imaged with enough angular resolution -- would exhibit features expected from theory but not possible to extract from spectra. We may group these by…

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…

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…
