Gravitational Lens Finding

Description

This project focuses on the task of lens finding in the currently available wide-field surveys (e.g., HSC-SSP). The expected number of strong lenses in the large surveys is significantly overpowered by the number of non-lensed objects, which leads to the high number of false positives in typical lens searches.

The goal of the project is to develop lens finding algorithms, apply them to the observational data, and assess the limitations of the algorithms (for example, analyse the properties of the identified lens population and examine the typical contaminants).
