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…
Cold dark matter subhaloes at arbitrarily low masses
Nicola C. Amorisco
A defining prediction of the cold dark matter (CDM) cosmological model is the existence of a very large population of low mass haloes, down to planet-size masses. However, their fa…
Dwarf stellar haloes: a powerful probe of small-scale galaxy formation and the nature of dark matter
Alis J. Deason, Sownak Bose, Azadeh Fattahi +3
We use N-body cosmological simulations and empirical galaxy models to study the merger history of dwarf-mass galaxies (with M_halo~10^10 M_Sun). Our input galaxy models describe th…
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…
