Gravitational Lensing
Gravitational lensing is a consequence of general relativity, where the gravitational force due to a massive object bends the paths of light originating from distant objects lying behind it. It then applies them to a diverse set of topics, including multiply imaged objects, time delays, extrasolar planets, microlensing, cluster masses, galaxy shape measurements, cosmic shear, and lensing of the cosmic microwave background. Using very little general relativity and no higher level mathematics, this text presents the basics of gravitational lensing, focusing on the equations needed to understand the phenomena.
The text will be especially relevant as large surveys such as LSST and Euclid begin to dominate the astronomical landscape. This approach allows undergraduate students and others to get quickly up to speed on the basics and the important issues. Designed for a one semester course, it
