Structured Variational Inference for Simulating Populations of Radio Galaxies

1 code implementation1 Feb 2021 David J. Bastien, Anna M. M. Scaife, Hongming Tang, Micah Bowles, Fiona Porter

We present a model for generating postage stamp images of synthetic Fanaroff-Riley Class I and Class II radio galaxies suitable for use in simulations of future radio surveys such as those being developed for the Square Kilometre Array.
