Course Synopses


  • Course Description:

    Gravitational lensing has matured into a thriving area of astrophysics, with applications across a wide range of scales and redshifts. The goals for this course are as follows:

    • Understand the theory and phenomenology of gravitational lensing.
    • Gain experience with quantitative aspects of lensing.
    • Examine a variety of astrophysical applications of lensing.

    We will develop the analytic theory as much as possible and consider computational approaches as appropriate. Some of the applications we will discuss include: properties of stars, planets, and stellar remnants; physical properties of galaxies; dark matter in galaxies and clusters of galaxies; structure of high-redshift galaxies and quasars; cosmological parameters.

    This is an advanced graduate course designed for students pursuing research in physics and astronomy. Undergraduate physics and mathematics should provide adequate preparation. Familiarity with intermediate classical mechanics, electrodynamics, and quantum mechanics are helpful, as much of the mathematics encountered in those subjects applies to lensing.
