A Study on Quenching and Galaxy Growth in z~1 Clusters using HST WFC3 Grism Observations
(2019-11-30)The work in this thesis uses 38 orbits worth of $\textit{Hubble Space Telescope}$ (HST), $\textit{Wide Field Camera 3}$ (WFC3) infrared F140W imaging and G141 grism data on 10 galaxy clusters at $z\sim1$ to study how the ... -
Revealing the Nature of Exoplanetary Atmospheres
(2019-10-26)The study of planets orbiting other stars, exoplanets, has entered the era of characterisation. When an exoplanet passes in front, or transits, its parent star, absorption features are imprinted into starlight passing ... -
Discovery and Characterisation of Gravitationally Lensed Quasars in Wide-field Surveys
(2019-10-25)The coincident alignment of two galaxies on the sky can create the rare cosmic phenomenon of strong gravitational lensing, in which light from the more distant galaxy is bent around the foreground galaxy to create multiple, ... -
Exploring Galaxy Clusters and Groups with Cosmological Simulations
(2019-11-24)Galaxy clusters are the largest gravitationally-bound objects in the Universe, their unparalleled size providing powerful leverage to probe large-scale structure growth and cosmology. At the same time, clusters and groups ...
