B.A. (Moderatorship) Honors Physics and Astrophysics: Physical Sciences

What is Astrophysics?
Since the dawn of human civilisation humans have gazed in wonder at the night sky. Astrophysics – the exploration of our solar system and the universe beyond – is still a major part of human endeavour in science. It covers everything from the sun and other stars to planets, galaxies and the cosmic microwave background.

Physics and Astrophysics: The course for you?
If you enjoy laboratory and computational work and have an interest in how fundamental physical theories explain how the universe took shape, then this may be the course for you.

Physics and Astrophysics at Trinity
The course includes core physics subjects as well as specialised courses in astronomical instrumentation, spectroscopy, the solar system, stellar evolution, supernovae, galaxies, interstellar matter, black holes and cosmology. Half of the third-year laboratory class is devoted to learning computational data handling techniques relevant for astrophysicists and the wider world of big data. The School of Physics is equipped with an 11” optical telescope and a 5 cm solar telescope for undergraduate use in the Monck Observatory. Physics and Astrophysics at Trinity offers you the opportunity to study with world-leading experts in the School of Physics, with modules designed to provide you with a flexible qualification for employment across a range of astrophysics research and industrial settings.

Your degree and what you’ll study
In the first two years you study Physics and Mathematics and one other subject. The Physics course includes topics in Astrophysics, Statistics, Mechanics, Thermodynamics, Electricity, Acoustics and Optics, Nuclear Physics and Quantum Physics. The Mathematics course includes topics in Calculus, Linear Algebra, Fourier Analysis and Mechanics. You spend three hours per week in experimental or computational laboratories. You will learn computer coding skills through the Python programming language.

In the third year you take modules in Physics and Astrophysics and spend one day per week working in the computer laboratory (first semester) or in the experimental laboratory (second semester). You also receive training in communication and presentation skills. In the fourth year you carry out an experimental or computational Capstone research project during the first nine weeks of the first semester and then take lecture modules in Physics and Astrophysics which cover core Physics and Astrophysics at a more advanced level. In the fourth year you carry out a Capstone research project either in Trinity or in a research laboratory abroad, mainly in Europe, Canada or the USA. This will allow you to develop your practical skills in a research environment, while learning about different countries and cultures.

Third-year modules
Quantum Mechanics, Electromagnetic Interactions, Condensed Matter Physics, Atomic and Nuclear Physics, Stellar and Galactic Structure, Computer Simulation, Statistical Thermodynamics and Astrophysical Spectroscopy, Experimental Techniques for Astrophysics.

Fourth-year modules
Planetary and Space Science, Cosmology, Computer Simulation, Quantum Physics, High Energy Physics, Electromagnetic Interactions, Modern Optics and Practical in Physics and Astrophysics.

Job Opportunity Potential

If you are an international student studying at Trinity, you might be considering internship and graduate work in Ireland, in your home country, or elsewhere. This section provides information for Non EU students on working in Ireland during and after your studies. For information and resources to support an international job search, see our Devex resource which includes international job search advice and information.

Employers value candidates who have more to offer than a good degree with high grades. They look for students who are well rounded and who have experience outside the classroom. Search for and take advantage of opportunities to gain experience, develop your skill set, and gain a clearer picture of what you like and don't like in terms of career options.

For example, you can get involved in some of the many student clubs and societies in college, volunteer or get a part time job. Remember that voluntary work is as valuable as paid work on your CV or resume - it's a great way to demonstrate your skills to future employers. Have a look at the TCD Civic Engagement website and check out volunteering opportunities in Ireland and abroad.
