Outflows and Dust in Quasars
Supermassive black holes (SMBHs) at the centres of galaxies are known to actively accrete, forming so-called `active galactic nuclei' (AGN) or `quasars'. These AGN are believed to feed back energy into their host galaxies, ... -
Basis Sets in Galactic Dynamics
Since their introduction in 1972 by Clutton-Brock, so-called biorthogonal basis sets have become a popular tool in galactic dynamics. They provide a method of solving Poisson's equation that scales linearly with the number ... -
Galaxy-Scale Signatures of Screened Modified Gravities
(2020-11-28)In recent years, theories of gravity incorporating a scalar field coupled to gravity---'scalar-tensor' theories---have been subject to increased attention. In these theories, the scalar field mediates gravitational-strength ... -
Polluted White Dwarfs: Insights into Ancient Extrasolar Planetary Systems
(2020-09-30)As the study of rocky exo-planets enters an era of characterisation, the ability to determine how similar a planet is to the Earth, and thus if it is potentially habitable, is fast approaching. An understanding of the ...
