Weak Lensing with the SKAO: Radio Shear Measurement
Priyamvad Tripathi, Marzia Rivi, Simon Prunet +2
Cosmic shear measurements have traditionally been dominated by optical surveys, which offer higher resolution, better sensitivity, higher galaxy number density, and wider area cove…
RadioLensfit: an HPC Tool for Accurate Galaxy Shape Measurement with SKA
Marzia Rivi, Lance Miller
The new generation radio telescopes, such as the Square Kilometre Array (SKA), are expected to reach sufficient sensitivity and resolution to provide large number densities of reso…
Cosmology with Phase 1 of the Square Kilometre Array; Red Book 2018: Technical specifications and performance forecasts
Square Kilometre Array Cosmology Science Working Group, David J. Bacon, Richard A. Battye +44
We present a detailed overview of the cosmological surveys that will be carried out with Phase 1 of the Square Kilometre Array (SKA1), and the science that they will enable. We hig…
Radio Galaxy Detection in the Visibility Domain
Adam Malyali, Marzia Rivi, Filipe B. Abdalla +1
We explore a new Bayesian method of detecting galaxies from radio interferometric data of the faint sky. Working in the Fourier domain, we fit a single, parameterised galaxy model…
Radio Weak Lensing Shear Measurement in the Visibility Domain - II. Source Extraction
Marzia Rivi, Lance Miller
This paper extends the method introduced in Rivi et al. (2016b) to measure galaxy ellipticities in the visibility domain for radio weak lensing surveys. In that paper we focused on…
Splotch: porting and optimizing for the Xeon Phi
Timothy Dykes, Claudio Gheller, Marzia Rivi +1
With the increasing size and complexity of data produced by large scale numerical simulations, it is of primary importance for scientists to be able to exploit all available hardwa…
