Towards measuring astrophysical third order correlation functions with the H.E.S.S. optical intensity interferometer
Andreas Zmija, Gisela Anton, Christopher Ingenhuett +7
The closure phase, the sum of the three Fourier phases in a telescope triangle, is an important tool in astronomical interferometry, helping to reconstruct the geometries of the ob…
