Is Earendel a Star? Investigating the Sunrise Arc Using JWST Strong and Weak Gravitational Lensing Analyses

open access: yesThe Astrophysical Journal
The galaxy cluster WHL J013719.8−08284 at z = 0.566 exhibits a strong-lensing feature known as the Sunrise Arc, which hosts Earendel, the most distant candidate star observed to date at z  ≈ 6.2.

Bayesian analysis of weak gravitational lensing

open access: yes, 2016
This thesis is concerned with how to extract cosmological information from observations of weak gravitational lensing – the modification of observed galaxy images due to gravitational lensing by the large-scale structure of the Universe. Firstly, we are concerned with how we can use all possible observa- tional probes of weak lensing to squeeze out as ...
