Quantum radio astronomy: Data encodings and quantum image processing
Jean-Paul Richard Kneib, Emma Elizabeth Tolley, Stefano Corda
We explore applications of quantum computing for radio interferometry and astronomy using recent developments in quantum image processing. We evaluate the suitability of different quantum image representations using a toy quantum computing image reconstruc ...
Elsevier2024Iterative removal of sources to model the turbulent electromotive force
We describe a novel method to compute the components of dynamo tensors from direct magnetohydrodynamic (MHD) simulations. Our method relies upon an extension and generalization of the standard H & ouml;gbom CLEAN algorithm widely used in radio astronomy to ...
Oxford Univ Press2024Hydrogen Intensity and Real-Time Analysis Experiment: 256-element array status and overview
Jean-Paul Richard Kneib, Emma Elizabeth Tolley, Carolyn Marie Crichton, Zeyu Zhang, Martin Kunz
The Hydrogen Intensity and Real-time Analysis Experiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the South African Radio Astronomy Observatory Square Kilometer Array site in Sout ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2022Strong Heuristics for Named Entity Linking
Robert West, Akhil Arora, Marko Culjak, Andreas Oliver Spitz
Named entity linking (NEL) in news is a challenging endeavour due to the frequency of unseen and emerging entities, which necessitates the use of unsupervised or zero-shot methods. However, such methods tend to come with caveats, such as no integration of ...
ASSOC COMPUTATIONAL LINGUISTICS-ACL2022Development and evaluation of galaxy shape measurement algorithms for radio interferometric data
The purpose of this Thesis is to develop, test, and characterize different models attempting to tackle the problem of measurement of galaxy shapes applied in interferometric observations. Shape measurement is a tool for estimating the underlying shear due ...
EPFL2021Microwave or millimeter wave passive components or devices
Romain Christophe Rémy Fleury, Maliheh Khatibi Moghaddam
A passive device comprising a hollow waveguide including first and second wall structures extending in a guiding direction, an interconnecting base extending between the wall structures and an enclosure extending between the wall structures, the enclosure ...
