The Host Galaxies of Luminous Reddened Quasars at z~2
(2018-10-20)The work in this thesis concerns the host galaxies of a class of luminous, yet heavily-obscured, quasars at z$\sim$2 - a peak epoch of both star formation and black hole accretion. Here, we seek to characterise the ... -
EXOCOMETS AT LARGE ORBITAL RADII AND THEIR INWARD TRANSPORT IN DEBRIS DISCS
(2018-10-20)Planetary systems are not only composed of planets, but also of km-sized rocky and icy bodies that are confined within belts similar to the Asteroid and Kuiper belt in the Solar System. Mutual collisions within these belts ... -
