Systematic errors induced by the elliptical power-law model in galaxy-galaxy strong lens modeling
Xiaoyue Cao, Ran Li, J. W. Nightingale +9
The elliptical power-law (EPL) model of the mass in a galaxy is widely used in strong gravitational lensing analyses. However, the distribution of mass in real galaxies is more com…
Galaxy-galaxy strong lens perturbations: line-of-sight haloes versus lens subhaloes
Qiuhan He, Ran Li, Carlos S. Frenk +8
We rederive the number density of intervening line-of-sight haloes relative to lens subhaloes in galaxy-galaxy strong lensing observations, where these perturbers can generate dete…
Halo concentration strengthens dark matter constraints in galaxy-galaxy strong lensing analyses
Nicola C. Amorisco, James Nightingale, Qiuhan He +8
A defining prediction of the cold dark matter (CDM) cosmological model is the existence of a very large population of low-mass haloes. This population is absent in models in which…
PyAutoLens: Open-Source Strong Gravitational Lensing
James. W. Nightingale, Richard G. Hayes, Ashley Kelly +14
Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens gala…
