Cosmology using Strong Gravitational Lensing
Angela L. H. Ng
The light we observe from distant astrophysical objects including supernovae and quasars allows us to determine large distances in terms of a cosmological model. Despite the succes…

A Geometric Probe of Cosmology -- II. Gravitational Lensing Time Delays and Quasar Reverberation Mapping Revisited
Angela L. H. Ng
The time delay between images of strongly gravitationally lensed quasars is an established cosmological probe. Its limitations, however, include uncertainties in the assumed mass d…

A Geometric Probe of Cosmology: I. Gravitational Lensing Time Delays and Quasar Reverberation Mapping
Angela L. H. Ng, Geraint F. Lewis
We present a novel, purely geometric probe of cosmology based on measurements of differential time delays between images of strongly lensed quasars due to finite source effects. Ou…
