Module: Advanced GR 1: Gravitational Waves

Module Specifications.

Current Academic Year 2024 - 2025

All Module information is indicative, and this portal is an interim interface pending the full upgrade of Coursebuilder and subsequent integration to the new DCU Student Information System (DCU Key).

As such, this is a point in time view of data which will be refreshed periodically. Some fields/data may not yet be available pending the completion of the full Coursebuilder upgrade and integration project. We will post status updates as they become available. Thank you for your patience and understanding.

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.

Reassessment Requirement Type
Resit arrangements are explained by the following categories: Resit category 1: A resit is available for both* components of the module. Resit category 2: No resit is available for a 100% continuous assessment module. Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
This module is category 1
