The Weak Lensing Hat-Trick: Constraining Cosmology with Galaxy, CMB, and Kinematic Lensing
… decade in which weak gravitational lensing surveys are probing the universe with unparalleled volume and precision. These surveys will produce not only high-quality images of hundreds of millions of galaxies and high-resolution microwave sky maps, but also create challenges in terms of …

Testing New Weak Lensing Measurement Techniques With The Dark Energy Survey
… of wind at the Blanco Telescope, the home of the Dark Energy Camera (DECam), on Dark Energy Survey (DES) image quality. We find it to have a likely negligible impact on the weak gravitational lensing measurements conducted with images taken during high wind. We then present the methods and …

Early Type Galaxies And Reliable Galaxy Cluster Selection
… and accurately analyze data from large cluster surveys, such as the South Pole Telescope (SPT), the Blanco Cosmology Survey (BCS) and the upcoming Dark Energy Survey (DES), which now extends to the galaxy formation and evolution studies. Through this thesis project followed by immediate …

Discovery and Characterisation of Gravitationally Lensed Quasars in Wide-field Surveys
… quasar, and dedicated spectroscopic and imaging surveys have added over one hundred new systems to this list. In recent years, the amount of available data across the whole-sky has grown exponentially. Full-sky data from X-ray to radio wavelengths exist, and predictions suggest there are many …

The Host Galaxies of Luminous Reddened Quasars at z~2
… the quasar. With combined observations from the Dark Energy Survey (DES), the VISTA Hemisphere Survey (VHS) and the UKIDSS Large Area Survey (ULAS), we exploit the quasar dust extinction in our sample to demonstrate that the quasar and galaxy emission can be separated via SED-fitting in these …

The structure and evolution of dark matter halos and their implications for cosmology
This is a study of how the properties of dark matter halos can be used to probe fundamental questions in cosmology. Similar to the inner regions of a halo the outer density profiles of the dark matter halo carry a wealth of information regarding its formation epoch, accretion history and …

Cosmology Using Photometric Samples of Type Ia Supernovae: The First Joint Photometric Light Curve Analysis
… and handle ever-smaller systematics.The Dark Energy Survey (DES) Supernova program has recently completed, and will be the first program whose success relies on the analysis of a sample in which we do not know the typing of the supernova. These `photometric samples' are a significant …
