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…
Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes
K. Abe, S. Abe, J. Abhir +439
We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…
GRB 221009A: Observations with LST-1 of CTAO and Implications for Structured Jets in Long Gamma-Ray Bursts
LST Collaboration, K. Abe, S. Abe +328
GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing…
Time-Dependent Modeling of the Sub-Hour Spectral Evolution During the 2013 Outburst of Mrk 421
MAGIC Collaboration, K. Abe, S. Abe +192
In April 2013, the TeV blazar Markarian~421 underwent one of its most powerful emission outbursts to date. An extensive multi-instrument campaign featuring MAGIC, VERITAS, and \tex…
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…
