Lenses In VoicE (LIVE): Searching for strong gravitational lenses in the VOICE@VST survey using Convolutional Neural Networks

We present a sample of 16 likely strong gravitational lenses identified in the VST Optical Imaging of the CDFS and ES1 fields (VOICE survey) using Convolutional Neural Networks (CNNs). We train two different CNNs on composite images produced by superimposing simulated gravitational arcs on real Luminous Red Galaxies observed in VOICE. Specifically, the first CNN …

Multi-tasking the growth of cosmological structures

A new preprint by Louis Perenon, Matteo Martinelli, Stéphane Ilić, Roy Maartens, Michelle Lochner and Chris Clarkson has been posted on the arXiv. Read the abstract below. Next-generation large-scale structure surveys will deliver a significant increase in the precision of growth data, allowing us to use `agnostic’ methods to study the evolution of perturbations without …
