Description

This module develops the physics of gravitational waves in general relativity, from their generation and propagation to their observable consequences.

Learning Outcomes

1. Predict gravitational waveforms in novel physical systems using the quadrupole formula and identify when such results are reliable.
2. Predict the physical effects of gravitational waves in novel situations, using this to analyze and propose potential detection strategies.
3. Compute and contrast the effects of different background geometries on the propagation of gravitational waves.
4. Translate between exact, linearized, and high-frequency models of gravitational waves, identifying their limitations and applying them to make predictions about novel physical systems.
