Cosmography with cluster strong lenses: the influence of substructure and line-of-sight halos
Anson D'Aloisio, Priyamvada Natarajan
We explore the use of strong lensing by galaxy clusters to constrain the dark energy equation of state and its possible time variation. The cores of massive clusters often contain…
Cosmological Constraints from Strong Gravitational Lensing in Galaxy Clusters
Eric Jullo, Priyamvada Natarajan, Jean-Paul Kneib +4
Current efforts in observational cosmology are focused on characterizing the mass-energy content of the Universe. We present results from a geometric test based on strong lensing i…
Virialization of high redshift dark matter haloes
Andrew Davis, Anson D'Aloisio, Priyamvada Natarajan
We present results of a study of the virial state of high redshift dark matter haloes in an N-body simulation. We find that the majority of collapsed, bound haloes are not virializ…
