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…
Fundamental Physics with the Square Kilometre Array
A. Weltman, P. Bull, S. Camera +50
The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity an…
Radio-Optical Galaxy Shape and Shear Correlations in the COSMOS Field using 3 GHz VLA Observations
Tom Hillier, Michael L. Brown, Ian Harrison +1
We present a weak lensing analysis of the 3 GHz VLA radio survey of the COSMOS field, which we correlate with overlapping HST-ACS optical observations using both intrinsic galaxy s…
Weak gravitational lensing with CO galaxies
Philip Bull, Ian Harrison, Eric Huff
Optical weak lensing surveys have become a powerful tool for precision cosmology, but remain subject to systematic effects that can severely bias cosmological parameter estimates i…
Radio Galaxy Shape Measurement with Hamiltonian Monte Carlo in the Visibility Domain
M. Rivi, M. Lochner, S. T. Balan +2
Radio weak lensing, while a highly promising complementary probe to optical weak lensing, will require incredible precision in the measurement of galaxy shape parameters. In this p…
The Tiered Radio Extragalactic Continuum Simulation (T-RECS)
Anna Bonaldi, Matteo Bonato, Vincenzo Galluzzi +5
We present the Tiered Radio Extragalactic Continuum Simulation (T-RECS): a new simulation of the radio sky in continuum, over the 150 MHz-20 GHz range. T-RECS models two main popul…
