Investigation of mass substructure in gravitational lens system SDP.81 with ALMA long-baseline observations
H. R. Stacey, D. M. Powell, S. Vegetti +2
The prevalence and properties of low-mass dark matter haloes serve as a crucial test for understanding the nature of dark matter, and may be constrained through the gravitational d…

Complex angular structure of three elliptical galaxies from high-resolution ALMA observations of strong gravitational lenses
H. R. Stacey, D. M. Powell, S. Vegetti +4
The large-scale mass distributions of galaxy-scale strong lenses have long been assumed to be well-described by a singular ellipsoidal power-law density profile with external shear…
