Astrophysics & Relativity

You will also learn a variety of computational and data analysis skills that are highly sought-after in a wide range of industries.



You can find out more from our academics below:

• Black Holes

• Extragalactic Astronomy & Cosmology

• Gravitational Waves

• High Energy Astrophysics



The detection of gravitational waves by the LIGO and VIRGO gravitational wave observatories and developments in electromagnetic based observations are contributing to the continued growth of the fields of astrophysics and cosmology, for example the direct imaging of the black hole at the centre of the galaxy M87 by the Event Horizon Telescope. There is a need to increase the number of scientists with the advanced knowledge and skills required to work in these fields, modelling the behaviour of high-energy sources, predicting their electromagnetic and gravitational wave emissions, observing these signals, and analysing the corresponding data streams.



The course is jointly run by the DCU School of Mathematical Sciences and the DCU School of Physical Sciences and led by researchers from the Centre for Astrophysics and Relativity (CfAR).



The course involves three main strands: Astrophysics, Relativity, and Computational Science and Data Analysis. All topics are covered in the first semester of the course, laying the foundations for the advanced study of these topics in the second semester.



In the General Relativity strand of the programme, you will study both astrophysical and fundamental physical properties of Black Holes, including gravitational collapse, the laws of black hole mechanics and Hawking radiation. You will learn about the generation of gravitational waves by the collision of black holes and other astrophysical processes and their propagation across the universe. You will also learn the science behind their detection by ground- and space-based observatories.



In Astrophysics, you will study Plasma Astrophysics, High Energy Astrophysics, Galaxies, and will supplement this knowledge with the study of observational techniques. You will learn about the formation and evolution of galaxies. You will gain deep insight into the plasma astrophysics governing star formation, planet formation and interstellar turbulence. In relation to High Energy Astrophysics, you will study the processes that lead to the emission of X-rays and gamma-rays from different sources, and how these are detected.



As part of the programme, all students undertake a project in a chosen area of Astrophysics or Relativity. Students are individually supervised by academics and researchers from CfAR, and apply their theoretical and computational skills to cutting edge research in Astrophysics and Relativity. In addition, by completing the project, students will develop transferable skills in relation to research, technical writing and scientific communication.



All students will also take modules in Computational Physics and in Data Analysis. As well as supporting your study of Astrophysics and Relativity, these modules will equip you with skills in computing and in analysing ‘big data’ that are of immediate relevance in a wide range of careers, including information and communications technology, engineering, banking and finance.

Semester 1 - Module Outlines

EE514 Data Science and Machine Learning

This module will equip students with the skills to handle and analyse large, complex data sets. Topics from probability, statistics and computing, and data science will be covered, and students will apply these in a variety of settings, including astrophysics and relativity.



MS536 Differential Geometry and General Relativity



This module introduces students to General Relativity – Einstein’s geometric theory of the gravitational field – and provides them with the mathematical tools required for its study. General Relativity underpins a wide range of astrophysical phenomena where gravitation is the dominant force at work (black holes, the Big Bang, gravitational wave emission), and where precision measurements of phenomena influenced by gravity are important (the GPS system). The module includes the study of the conceptual foundations of GR and Einstein's equation and the applications of this theory to our universe.



MS509 Partial Differential Equations



This module introduces students to both the methods and underlying theory of solving partial differential equations. Students will become familiar with first-order quasi-linear and second-order linear partial differential equations. A selection of analytic techniques for solving some partial differential equations that frequently occur in applications will be given. This module provides both a platform for modeling with partial differential equations and an introduction to analysing the nature of these equations. Students will develop an ability to critique the various solution methods and demonstrate a deep understanding of when and why they can be used.



PS526 Theoretical Astrophysics



In this module, students will study the life cycle of stars of different masses, and study the role of radiative processes in a variety of astrophysical phenomena. They will analyse the key role of plasmas in astrophysics, and study the structure and formation of the interstellar medium. They will analyse and critique different models of stellar and galactic formation.



Semester 2 - Module Outlines

PS530 Computational Physics



In this module, students will be introduced to the ideas of computational astrophysics including programming language paradigms, numerical methods, algorithms, stochastic methods, and high-performance computing. Students will have the option to learn and use different programming languages including Python, C, and C++.



PS528 Extragalactic Astrophysics



This module focuses on a general understanding of the properties of galaxies and the intergalactic medium, along with the different observational techniques used to study them.



PS529 High Energy Astrophysics



This module focuses on the non-thermal processes governing the high energy Universe, including radiative processes and particle acceleration. The objects of study range from our Sun to Active Galactic Nuclei, to Gamma Ray Bursts, and to the Universe as a whole.



MS539 Gravitational Waves



The recent direct detection of gravitational waves has opened up a qualitatively new window into astronomy and fundamental physics, and this module provides students with a foundation in this area. The physics of gravitational waves will be developed in general relativity, from the generation and propagation of these waves through to their observable consequences.



MS540 Black Hole Physics



This module covers both classical and quantum aspects of black holes. Topics include the no-hair conjecture, black hole formation, laws of black hole mechanics, Hawking radiation and black hole thermodynamics, black hole evaporation, and the information loss 'paradox'.



Semester 3 - Module Outline

FSH512 Project (Astrophysics and Relativity)
