Recent PhD Submission

12 May 2015

David's PhD involved studying the faintest galaxies, known as ultra-faint dwarf galaxies (UFDs), which have been discovered in the past decade. The stars in all these systems are all very ancient and contain low proportions of elements heavier than helium. This makes them fossils with relatively clean signatures of the first stars, meaning that they can be used to study the chemical history of the early universe. Their relative proximity gives a method of studying the early universe without the need to look at very distant objects.

Congratulations, David!
