Sub 35-ps Single-Photon Stellar Intensity Interferometry of Vega

SII enables measurements of stellar photospheres by correlating intensity fluctuations, offering a robust alternative to amplitude-based techniques. With the advent of modern single-photon counting detectors, this method has re-emerged as a powerful technique in stellar interferometry exploiting their ultra-high timing...

Sephira: stellar intensity interferometry with the MAST Array Telescopes

Stellar intensity interferometry (SII) measures correlations in photon arrival times between independent apertures. Unlike amplitude interferometry, SII requires no optical beam combination: telescopes need only record photon timestamps locally, which are then correlated in post-processing. This eliminates the need for...
