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 ...
Elsevier2024Neutrino Signal from a Population of Seyfert Galaxies
IceCube Collaboration has previously reported evidence for a neutrino signal from a Seyfert galaxy NGC 1068. This may suggest that all Seyfert galaxies emit neutrinos. To test this hypothesis, we identify the best candidate neutrino sources among nearby Se ...
Amer Physical Soc2024Performance of the Quasar Spectral Templates for the Dark Energy Spectroscopic Instrument
Millions of quasar spectra will be collected by the Dark Energy Spectroscopic Instrument (DESI), leading to a fourfold increase in the number of known quasars. High-accuracy quasar classification is essential to tighten constraints on cosmological paramete ...
IOP Publishing Ltd2023Electronic Structure of Few-Layer Black Phosphorus from & mu;-ARPES
Nicola Marzari, Marco Gibertini, Samuel Poncé, Christophe Berthod
Black phosphorus (BP) stands out among two-dimensional(2D) semiconductorsbecause of its high mobility and thickness dependent direct band gap.However, the quasiparticle band structure of ultrathin BP has remainedinaccessible to experiment thus far. Here we ...
AMER CHEMICAL SOC2023The Pristine survey - XVI. The metallicity of 26 stellar streams around the Milky Way detected with the STREAMFINDER in Gaia EDR3
Pascale Jablonka, Carmela Lardo
We use the photometric metallicities provided by the panoramic Pristine survey to study the veracity and derive the metallicities of the numerous stellar streams found by the application of the STREAMFINDER algorithm to the Gaia Early Data Release 3 data. ...
OXFORD UNIV PRESS2022Detectability of Large Correlation Length Inflationary Magnetic Field with Cherenkov Telescopes
Magnetic fields occupying the voids of the large scale structure may be a relic from the Early Universe originating from either Inflation or from cosmological phase transitions. We explore the possibility of identifying the inflationary origin of the void ...
2022UNITSIM-Galaxies: data release and clustering of emission-line galaxies
New surveys such as European Space Agencys (ESA's) Euclid mission are planned to map with unprecedented precision the large-scale structure of the Universe by measuring the 3D positions of tens of millions of galaxies. It is necessary to develop theoretica ...
OXFORD UNIV PRESS2022Rotation measure and synchrotron emission signatures in simulations of magnetized galactic discs
We analyse observational signatures of magnetic fields for simulations of a Milky Way-like disc with supernova-driven interstellar turbulence and self-consistent chemical processes. In particular, we post-process two simulations data sets of the SILCC Proj ...
OXFORD UNIV PRESS2022Time delay lens modelling challenge
Frédéric Courbin, Martin Raoul Robert Millon, Aymeric Alexandre Galan, Vivien François Bonvin, Di Xu
In recent years, breakthroughs in methods and data have enabled gravitational time delays to emerge as a very powerful tool to measure the Hubble constant H-0. However, published state-of-the-art analyses require of order 1 yr of expert investigator time a ...
OXFORD UNIV PRESS2021Potential of Radio Telescopes as High-Frequency Gravitational Wave Detectors
In the presence of magnetic fields, gravitational waves are converted into photons and vice versa. We demonstrate that this conversion leads to a distortion of the cosmic microwave background (CMB), which can serve as a detector for MHz to GHz gravitationa ...
