---------------------------------------------------------------------------------------------- Project: Z1 Title: Neutrino-oscillation measurements with IceCube DESY group: IceCube Type: Online project Duration: 19th July - 10th Sep 2021 Description: The IceCube DeepCore experiment is responsible for the World's most precise measurements of atmospheric neutrino oscillations, a quantum mechanical phenomenon that emerges due to differences in neutrino masses. Our measurement of this process is unique in that we observe it at higher energies than contemporary experiments. Our data is therefore of great value to the global community, and we aim to make it readily available for global analyses. In this project, students will prepare the data for a public release that was used in the most recent analysis of neutrino oscillations, and validate it by reproducing the results. Special Qualifications expected: - experience with linux (or similar) operating system - knowledge of python Link to further information: https://astro.desy.de/neutrino_astronomy/icecube/index_eng.html ---------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------- Project: Z2 Title: Quantum mechanics on a discrete time lattice DESY group: Zeuthen Particle Physics Theory Type: Online project Duration: 19th July - 10th Sep 2021 Description: In the project, an introduction to the Feynman’s pathintegral approach to quantum mechanics will be obtained. In particular, the harmonic oscillator should be worked out on a discrete time lattice. After a rotation to Euclidean time, the system shall be investigated through a Monte Carlo simulation. Therefore, in the project the pathintegral formulation, the lattice discretization, Monte Carlo simulations and error analysis will be learned. The project will follow closely the article by Creutz and Freedman https://www.zeuthen.desy.de/~kjansen/lattice/qcd/miscellaneous/CreutzFreedman.pdf Special Qualifications expected: basic knowledge in quantum mechanics, mastering of a programming language, e.g. Python, Julia, C, matlab ... ---------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------- Project: Z3 Title: Time-domain astronomy with the HESS gamma-ray telescopes DESY group: HESS Type: Online project Duration: 19th July - 10th Sep 2021 Description: Time-domain astronomy is a very dynamic field in contemporary astrophysics and investigates phenomena such as fast radio bursts, gamma-ray bursts, novae or tidal disruption events on timescales from milliseconds to months. The study of these objects requires observations with telescopes across the electromagnetic spectrum or with even alternate messengers like neutrinos and gravitational waves. However, estimating the capabilities of different instruments to follow-up specific astrophysical sources requires a tool to predict the sensitivity of telescopes on diverse timescales. The aim of this summer student project is the development of such a tool for the gamma-ray regime and application to a to-be-defined science case. Special Qualifications expected: Experience in shell and python programming is advantageous. ---------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------- Project: Z4 Title: Binary observations with the CTA gamma-ray observatory. DESY group: VERITAS / CTA Type: Online project Duration: 19th July - 10th Sep 2021 Description: CTA is the next-generation gamma-ray astronomy observatory currently constructed on the Island of La Palma and in the Atacama Desert in Chile. The summer student will study the sensitivity if CTA to high-energy emission from binary systems consistent of a compact object (neutron star or black hole) and a massive star. The project will imply Monte Carlo simulations and modern data analysis methods taking into account sources properties and the characteristics of the CTA observatory. Special Qualifications expected: Knowledge in data analysis and python or C++ programming ---------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------- Project: Z5 Title: Machine learning tool for ASTRA results analysis DESY group: Pitz Type: Online project Duration: 19th July - 10th Sep 2021 Description: Develop and demonstrate a software tool using machine learning to approximate and predict beam properties of ASTRA simulation results. Beam dynamics of space charge dominated beams in photo injectors is very limited in analytic solutions and requires time consuming simulations using macroparticle tracking algorithms, like ASTRA code. Machine learning algorithms allow prediction of results from input parameters without exact knowledge on the model. Using machine learning, many points in the ASTRA parameter space could be studied without running long time simulations for every setup. The summer student will develop and demonstrate a software tool using machine learning to approximate and predict particle beam properties of ASTRA simulation results. Special Qualifications expected: Knowledge on accelerator physics and programming skills in Python programming language are highly desirable.
