Constraints on the inner density profile of dark-matter haloes from weak gravitational lensing
We construct two linear filtering techniques based on weak gravitational lensing to constrain the inner slope $\alpha$ of the density profile of dark-matter halos. Both methods combine all available information into an estimate of this single number. Under idealised assumptions, $\alpha$ is constrai...
