Did Zhao & Qin Solve the Apparant Conflict Beween Gravitational Lens Time Delays, Dark Matter and the Hubble Constant?
C. S. Kochanek
The solution proposed by Zhao & Qin to the apparent conflict between gravitational lens time delays, local estimates of the Hubble constant and current expectations for the structu…

Strong Lensing Constraints on Small-Scale Linear Power
Neal Dalal, Christopher S. Kochanek
We place limits on the linear power spectrum on small scales (k > 50 h/Mpc) using measurements of substructure in gravitational lens galaxies. We find excellent agreement with the…
