Lensing Code

Short Description

One of our goals is to keep developing lens modelling codes targeted at high angular resolution observations. We strive to continually improve our approach to include an increasing number of physical effects and target an increasing variety of astrophysical questions. At the same time, we make use of Machine Learning approaches to quantify sources of systematic errors in lens modelling and extract valuable information from large samples of gravitational lens systems. For more details, see the list of publications below and here. If you are interested in using our methodology, get in touch.
