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…
A Systematic Search for MeV-GeV Pulsar Wind Nebulae without Gamma-ray Detected Pulsars
Jordan Eagle, Daniel Castro, Wei Zhang +3
An increasing number of pulsar wind nebulae (PWNe) are being identified in the TeV band by ground-based Imaging Air Cherenkov Telescopes such that they constitute the dominant sour…
Fermi detection of gamma-ray Emission from the Hot Coronae of Radio-quiet Active Galactic Nuclei
Jun-Rong Liu, Jian-Min Wang, Fermi-LAT Collaboration
Relativistic jets around supermassive black holes (SMBHs) are well-known powerful -ray emitters. In absence of the jets in radio-quiet active galactic nuclei (AGNs), how the SMB…
Periodic Gamma-ray Modulation of the blazar PG 1553+113 Confirmed by Fermi-LAT and Multi-wavelength Observations
S. Abdollahi, L. Baldini, G. Barbiellini +98
A 2.1-year periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in almost 7 year of data from the Fermi Large Area Tele…
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…
CTC and CT5TEA: an advanced multi-channel digitizer and trigger ASIC for imaging atmospheric Cherenkov telescopes
Benjamin Schwab, Adrian Zink, Davide Depaoli +12
We have developed a new set of Application-Specific Integrated Circuits (ASICs) of the TARGET family (CTC and CT5TEA), designed for the readout of signals from photosensors in came…
Acceleration and transport of relativistic electrons in the jets of the microquasar SS 433
F. Aharonian, F. Ait Benkhali, J. Aschersleben +161
SS 433 is a microquasar, a stellar binary system with collimated relativistic jets. We observed SS 433 in gamma rays using the High Energy Stereoscopic System (H.E.S.S.), finding a…
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…
Resource-aware Research on Universe and Matter: Call-to-Action in Digital Transformation
Ben Bruers, Marilyn Cruces, Markus Demleitner +34
Given the urgency to reduce fossil fuel energy production to make climate tipping points less likely, we call for resource-aware knowledge gain in the research areas on Universe an…
Ultra-Fast Generation of Air Shower Images for Imaging Air Cherenkov Telescopes using Generative Adversarial Networks
Christian Elflein, Stefan Funk, Jonas Glombitza
For the analysis of data taken by Imaging Air Cherenkov Telescopes (IACTs), a large number of air shower simulations are needed to derive the instrument response. The simulations a…
Incremental Fermi Large Area Telescope Fourth Source Catalog
LAT collaboration, Soheila Abdollahi, Fabio Acero +137
We present an incremental version (4FGL-DR3, for Data Release 3) of the fourth Fermi-LAT catalog of gamma-ray sources. Based on the first twelve years of science data in the energy…
Search for extended sources in the Galactic Plane using 6 years of Fermi-Large Area Telescope Pass 8 data above 10 GeV
The Fermi LAT Collaboration, M. Ackermann, M. Ajello +117
The spatial extension of a gamma-ray source is an essential ingredient to determine its spectral properties as well as its potential multi-wavelength counterpart. The capability to…
