Title: Hunting for dark matter substructure in Strong lensing with Neural networks
Speaker: Joshua Yao-Yu Lin (University of Illinois at Urbana-Champaign)

Location: General building II, R521
Abstract:
Dark Matter Substructures are interesting since they can reveal the properties of dark matter, especially the cold dark matter small-scale problems such as missing satellites problem. In recent years, it has become possible to detect individual dark matter subhalos near images of strongly lensed extended background galaxies. In this talk, I would discuss the possibility of using deep neural networks to detect dark matter subhalos, and showing some preliminary result with simulated data.
