  1. Finding fossil galaxy system progenitors using strong gravitational lensing

    Johnson, Lucas EdwardUniversity of Alabama Libraries2018

    … fossil progenitors in the CASSOWARY catalog of strong gravitational lensing demonstrates that not all fossils are old, and their formation histories are more complex than originally thought. These progenitors have optical characteristics consistent with them being the transition phase between …

  2. Investigating strong gravitational lensing with infrared space missions : AKARA, Spitzer and Herschel

    Hopwood, Rosalind Helen BevisThe Open University2011

    This thesis addresses the use of strong gravitational lensing to facilitate deep midinfrared observations of star-forming galaxies and to study highly dust obscured sub-millimetre galaxies (SMG). 15 <i>u</i>m extragalactic number counts were taken from ultra deep AKARI mapping of the gravitational …

  3. STRONG GRAVITATIONAL LENSING MODELLING OF GALAXY CLUSTERS IN THE ERA OF BIG DATA

    ABRIOLA, DAVIDEUniversità degli Studi di Milano2026

    … and surveys are revolutionizing the field of strong lensing (SL) by galaxy clusters. Remarkably, the Euclid Survey will cover approximately 15,000 square degrees of the sky, detecting SL features in thousands of massive clusters. Complementarily, the James Webb Space Telescope (JWST) is …

  5. Imaging the invisible : constraining dark matter distributions in galaxy clusters using strong gravitational lensing

    Corless, Virginia LeighMassachusetts Institute of Technology2005

    … thesis, I design and construct a Monte-Carlo gravitational lensing simulation that statistically studies the strong lensing of extended galactic sources by dark matter distributions in galaxy clusters, using recent work on cluster Abell 1689 as an empirical guide. By quantitatively comparing …

  6. Line-of-sight effects on strong lensing time delays

    Johnson, DanielDepartment of Astronomy2023

    The effects of matter along the line-of-sight in strong gravitational lensing systems is widely recognised to have a non-negligible effect on lensing observables. In this project, we explore the Dominant-Lens Approximation, a new theoretical formalism designed to parameterise these effects, paying …

  7. Discovery and Characterisation of Gravitationally Lensed Quasars in Wide-field Surveys

    Lemon, CameronUniversity of Cambridge2019

    … 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, distorted, and magnified images. When the background galaxy hosts a bright active galactic nucleus, a quasar, the …

  8. The evolution of dark and luminous structure in massive early-type galaxies

    Oldham, Lindsay JoannaUniversity of Cambridge2017

    In this thesis, I develop and combine strong lensing and dynamical probes of the mass of early-type galaxies (ETGs) in order to improve our understanding of their dark and luminous mass structure and evolution. Firstly, I demonstrate that the dark matter halo of our nearest brightest cluster galaxy …
