Direct Detection of CDM Substructure
N. Dalal, C. S. Kochanek
We devise a method to measure the abundance of satellite halos in gravitational lens galaxies, and apply our method to a sample of 7 lens systems. After using Monte Carlo simulatio…
Completeness in Photometric and Spectroscopic Searches for Clusters
Martin White, C. S. Kochanek
We investigate, using simulated galaxy catalogues, the completeness of searches for massive clusters of galaxies in redshift surveys or imaging surveys with photometric redshift es…
Constraints on the long-range properties of gravity from weak gravitational lensing
Martin White, C. S. Kochanek
Weak gravitational lensing provides a means of testing the long-range properties of gravity. Current measurements are consistent with standard Newtonian gravity and inconsistent wi…
Cusped Mass Models Of Gravitational Lenses
J. A. Munoz, C. S. Kochanek, C. R. Keeton
Recent observations of galaxy luminosity profiles and dark matter simulations find luminosity and mass distributions characterized by central cusps rather than finite core radii. W…
Global Probes of the Impact of Baryons on Dark Matter Halos
C. S. Kochanek, Martin White
The halo mass function, dn/dM, predicted by hierarchical clustering models can be measured indirectly using dynamical probes like the distribution of gravitational lens image separ…
