Deflection angle Introduction to <strong>Gravitational</strong> <strong>Lensing</strong> Applications<br />
Mapping of mass using Strong <strong>Lensing</strong><br />
• Recall this equation equation. In 2D case case, if the double images from<br />
a same source is identified, this equation can be solved to<br />
find the lens’ mass.<br />
• In real situation, where there are many different sources<br />
producing multiple images, a mass model is proposed and<br />
fitted to produced the corresponding multiple images.
