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. Tolila, 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…
Mobile Intensity Interferometer for Stellar Observations (MISO)
Christopher Ingenhütt, Pedro Batista, Gisela Anton +5
In recent years, intensity interferometry has seen renewed interest and successful application at Imaging Atmospheric Cherenkov Telescope arrays. These measurements are usually per…
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…
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…
Simultaneous Two Colour Intensity Interferometry with H.E.S.S
Naomi Vogel, Andreas Zmija, Frederik Wohlleben +4
In recent years, intensity interferometry has been successfully applied to the Imaging Atmospheric Cherenkov Telescopes H.E.S.S. , MAGIC, and VERITAS. All three telescope systems h…
First Intensity Interferometry Measurements with the H.E.S.S. Telescopes
Andreas Zmija, Naomi Vogel, Frederik Wohlleben +3
Intensity interferometry for astrophysical observations has gained increasing interest in the last decade. The method of correlating photon fluxes at different telescopes for high…
Optical intensity interferometry lab tests in preparation of stellar diameter measurements at IACTs at GHz photon rates
Andreas Zmija, Naomi Vogel, Gisela Anton +4
Astronomical intensity interferometry enables quantitative measurements of the source geometry by measuring the photon fluxes in individual telescopes and correlating them, rather…
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…
Science verification of the new FlashCam-based camera in the 28m telescope of H.E.S.S
Gerd Pühlhofer, Konrad Bernlöhr, Baiyang Bi +13
In October 2019 the central 28m telescope of the H.E.S.S. experiment has been upgraded with a new camera. The camera is based on the FlashCam design which has been developed in vie…
Astronomy outreach in Namibia: H.E.S.S. and beyond
Hannah Dalgleish, Heike Prokoph, Sylvia Zhu +6
Astronomy plays a major role in the scientific landscape of Namibia. Because of its excellent sky conditions, Namibia is home to ground-based observatories like the High Energy Spe…
TeV emission of Galactic plane sources with HAWC and H.E.S.S
H. Abdalla, F. Aharonian, F. Ait Benkhali +318
The High Altitude Water Cherenkov (HAWC) observatory and the High Energy Stereoscopic System (H.E.S.S.) are two leading instruments in the ground-based very-high-energy gamma-ray d…
