EON-SII: Design of a transportable picosecond stellar intensity interferometer for compact-star astrophysics
Thomas Schweizer, Josef Eder, Jürgen Besenrieder +5
Stellar intensity interferometry (SII) measures correlations in photon-arrival fluctuations recorded by telescopes observing bright celestial sources. It can resolve angular scales…
Design and Realization of the LST Main Structure for the Cherenkov Telescope Array
T. Schweizer, J. Eder, H. Wetteskind +12
The 23 m diameter Large Size Cherenkov Telescope (LST) for CTA, located at 2250 m a.s.l. on the Canary Island of La Palma, is the next-generation Cherenkov telescope following MAGI…
Adapting the 23m LST-North mechanical structure design for the strong Chile seismic environment
Thomas Schweizer, Josef Eder, Teshima Masahiro +2
The 23-meter-diameter Large-Sized Telescope (LST) is the largest size telescope of the next generation Cherenkov Telescope Array (CTA). The first telescope, LST-1, was installed at…
Direct comparison of SiPMs and PMTs in operation with a bright background and prospects of using SPADs as truly digital sensors
Razmik Mirzoyan, Alexander Hahn, David Fink +8
The use of silicon photomultipliers (SiPMs) alongside conventional photomultiplier tubes (PMTs) is a remarkable technological development in modern ground-based very high energy ga…
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…
Performance of MAGIC stellar intensity interferometer and expansion to MAGIC + CTAO-LST1 stellar intensity interferometer
Alejo Cifuentes, V. A. Acciari, F. Barnes +24
A new generation of optical intensity interferometers are emerging in recent years taking advantage of the existing infrastructure of Imaging Atmospheric Cherenkov Telescopes (IACT…
