High accuracy wide field imaging method in radio interferometry
Haoyang Ye, Steve F. Gull, Sze M. Tan +1
With the development of modern radio interferometers, wide-field continuum surveys have been planned and undertaken, for which accurate wide-field imaging methods are essential. Ba…
Direct Wide-Field Radio Imaging in Real-Time at High Time Resolution using Antenna Electric Fields
James Kent, Adam P. Beardsley, Landman Bester +6
The recent demonstration of a real-time direct imaging radio interferometry correlator represents a new capability in radio astronomy. However wide field imaging with this method i…
Optimal gridding and degridding in radio interferometry imaging
Haoyang Ye, Stephen F. Gull, Sze M. Tan +1
In radio interferometry imaging, the gridding procedure of convolving visibilities with a chosen gridding function is necessary to transform visibility values into uniformly sample…
Bayesian Source Discrimination in Radio Interferometry
Peter Hague, Haoyang Ye, Bojan Nikolic +1
Methods currently in use for locating and characterising sources in radio interferometry maps are designed for processing images, and require interferometric maps to be preprocesse…
Atmospheric PSF Interpolation for Weak Lensing in Short Exposure Imaging Data
C. Chang, P. J. Marshall, J. G. Jernigan +25
A main science goal for the Large Synoptic Survey Telescope (LSST) is to measure the cosmic shear signal from weak lensing to extreme accuracy. One difficulty, however, is that wit…
Fast cosmological parameter estimation using neural networks
T. Auld, M. Bridges, M. P. Hobson +1
We present a method for accelerating the calculation of CMB power spectra, matter power spectra and likelihood functions for use in cosmological parameter estimation. The algorithm…
