Sub 35-ps Single-Photon Stellar Intensity Interferometry of Vega
Verena G. Leopold, Sebastian Karl, Stefan Richter +7
SII enables measurements of stellar photospheres by correlating intensity fluctuations, offering a robust alternative to amplitude-based techniques. With the advent of modern singl…
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…
Photon counting intensity interferometry in the blue at a 0.5 m telescope
Sebastian Karl, Stefan Richter, Joachim von Zanthier
Intensity interferometry is a re-emerging interferometry tool that alleviates some of the challenges of amplitude interferometry at the cost of reduced sensitivity. We demonstrate…
Comparing Different Approaches for Stellar Intensity Interferometry
Sebastian Karl, Andreas Zmija, Stefan Richter +7
Stellar intensity interferometers correlate photons within their coherence time and could overcome the baseline limitations of existing amplitude interferometers. Intensity interfe…
A quantitative comparison of amplitude versus intensity interferometry for astronomy
Manuel Bojer, Zixin Huang, Sebastian Karl +3
Astronomical imaging can be broadly classified into two types. The first type is amplitude interferometry, which includes conventional optical telescopes and Very Large Baseline In…
