97. Supernova Remnants as Cosmic Accelerators: Simulation-Based Insights

Joana Dimitrova

09/09/2025, 13:00

The aim of this presentation is to provide an overview of a summer student project conducted within the Astroparticle Physics Theory group. Supernova remnants (SNRs) are key astrophysical sites for the acceleration of cosmic rays, and their observable signatures provide valuable insights into high-energy astrophysical processes. In this project, hydrodynamic simulations of supernova explosions...

Emiliia Ortynska

09/09/2025, 13:20

This project focuses on the gamma-ray binaries LS I +61 303 and HESS J0632+057, analyzed with data from the VERITAS array during the DESY Summer School. The project aimed to investigate variability in flux and spectral parameters beyond orbital modulation and to search for extended emission possibly associated with a pulsar wind nebula. To achieve these aims, the project is structured in two...

106. Correlation Analysis of H.E.S.S. gamma-ray and Southern Galactic Plane Survey neutral atomic hydrogen maps

Olena Pastoven

09/09/2025, 13:40

This work focuses on developing automated methods for identifying correlations between two-dimensional gamma-ray maps obtained with the H.E.S.S. telescope array and three-dimensional neutral atomic hydrogen maps from the Southern Galactic Plane Survey. Detecting such correlations is important for studying the interaction of cosmic rays with the interstellar medium and for constraining the...

107. LLM Applications in High Energy Astronomy

Elisa Jones

09/09/2025, 14:00

The growing complexity of telescope configurations, such as those in the Cherenkov Telescope Array Observatory (CTAO), demands efficient and reliable tools for data modeling and validation. This project presents a multi-agent application, called 'CTAgent', designed to automate the generation of Pydantic Python models directly from free-text descriptions or structured files. It also explores...

108. Characterization of Neutrino Hotspots: Minimum Angular Cut and Sensitivity to Diffuse Flux

Gulliermo Lagunas Gualda

09/09/2025, 14:40

This work evaluates the performance of a neutrino hotspot-population analysis on simulated sky maps, with the aim of quantifying the ability to distinguish injected point sources from a diffuse background and of characterizing the angular accuracy of reconstructed hotspots. First, background sky maps were compared to a Poisson distribution to justify the choice of a minimum angular separation;...

109. Double Cascades Reconstruction Algorithm in IceCube

Kevin Kansutthiwiwat

09/09/2025, 15:00

The study of high-energy neutrino events provides a means to probe the nature of numerous phenomena in the universe. This is because neutrinos interact with matter via the weak interaction and gravity. Neutrinos come in different flavors and can oscillate from one flavor to another. Different neutrino interactions with matter produce distinct light topologies, which can be detected by the...

110. Learning about radio at DESY: The first steps in a new radio antenna outreach project

Amy Hall

09/09/2025, 15:20

Radio antennas are crucial to our day-to-day life as they cover a wide range of tasks; from amateur communications to next-generation science experiments. Therefore, outreach projects explaining how antennas work provide an excellent entry point for students into many disciplines, including astroparticle physics. Throughout this project various antennas and software defined radios (SDRs) were...

111. Study of Electric Current Induced by the deflection of Blazar-induced TeV Pairs in a Homogenous IGMF

Bahaa Asad

10/09/2025, 09:30

The Relativistic electron-positron pairs produced by high energy gamma rays (more than TeV) can produce about GeV cascade gamma rays via Inverse Compton Scattering. The produced +e/-e and the cascade gamma ray had been found to be absent in the gamma ray spectra of several Blazars. This absence is due to the deflection of the motion of the charged particles due to the existence of the...

This presentation aims to provide an outline of a summer student research project in the K-40 Radiation for Advanced Neuroimaging Of Strokes (KRANOS) group. The collaboration is centred around research and development of the detection system which will use Silicon Photomultipliers to identify potassium-40 concentrations in the brain. After indirect electron capture, K-40 decays into Ar-40...

114. 4D Phase Space Analysis Aimed at x-y Coupling Characterization of Electron Beams

Naida Ustavdic

10/09/2025, 10:50

The aim of this presentation is to give overview of a Summer Student Project, done within the Photo-Injector Teststand at DESY Zeuthen (PITZ). Emittance (volume in the trace space occupied by the beam) and plane coupling of the beam are important measures of the beam quality. Emittance should be low and there should be no x-y coupling. At the PITZ accelerator, recent measurements indicated...

One of the issues encountered is that the beam is deflected by the Earth’s magnetic field and a possible residual field, complicating the task of...

116. An Introduction to Matrix Product State Algorithms

Nicholas Woodford

10/09/2025, 11:30

Tensor Networks were developed in Many-Body Quantum Physics for describing many-body wavefunctions. Matrix Product States are a simple 1D ansatz which lends itself to efficient computation and as such have been explored for many applications in MBQP and beyond. I give an overview of some of the most common MPS algorithms and their uses: the Tensor Cross Interpolation for efficiently finding...
