Course aims to offer knowledge and expertise for a career in the academic world, industry or to pursue a variety of other opportunities in which a strong background in physics, astrophysics or computing is useful and important.
The Astronomy & Astrophysics research group at Cardiff University studies a range of topics in galactic and extragalactic astronomy and cosmology, including both theory and observation, and the development of astronomical instrumentation related to these topics. Major subjects include: observations of high-redshift galaxies and their implications for both cosmology and galaxy formation; theoretical, computational and observational studies of the formation of stars and planetary systems; the design and construction of astronomical instrumentation, especially at millimetre and sub-millimetre wavelengths, for ground and space-based observatories and for studies of the Cosmic Microwave Background; theoretical work on early Universe cosmology and the large-scale structure of the Universe.

Our principal objectives have to do with Origins: measuring the fluctuations from which the first clusters of galaxies formed; probing the formation, structure and evolution of galaxies, both today and at large look-back times; detecting new forms of matter; determining the relative abundances of the chemical elements in different parts of the Universe; detecting stars and planets in the earliest stages of formation and charting their birth throes.
These observational and instrumental activities are complemented by a strong and diverse theoretical programme which is also aimed at answering Origins questions, such as:
- what determines the structure and dynamics of the enormous molecular clouds from which new stars and planets form
- the efficiency of star formation and the masses with which stars form
- the clustering properties of stars and why most stars are born in binary systems
- how galaxies form and how galaxies in clusters inter act with one another
- how, when and where the chemical elements are synthesised
- how the evolution and appearance of the Universe are affected by dust
- how the process of galaxy formation relates to cosmology, particularly the large-scale structure of the "cosmic web"
These projects make extensive use of computer modelling and simulations, using national and international supercomputers, as well as powerful in-house parallel machines.
Another major activity is fundamental research in general relativity and gravitational wave astronomy. This includes both the design of gravitational wave telescopes, in particular the processes used to extract and analyse the extremely subtle signals they record; and prediction of the signals to be expected from likely sources such as black holes, supernovae, pulsars, inspiralling and coalescing neutron stars, and quantum processes occurring in the early Universe.
