Identifying Rings in IFU Surveys

Gravitational lensings provide unique opportunities to study distant galaxies. Despite their usefulness, only a dozens of gravitational arcs have been reported up-to-date, hampered by the low resolution imaging from ground-based surveys. We propose a novel method to identify Einstein rings/arcs in t...
