Reconstructing the Thomson Optical Depth due to Patchy Reionization with 21-cm Fluctuation Maps
Gilbert Holder, Ilian T. Iliev, Garrelt Mellema
Large fluctuations in the electron column density can occur during the reionization process. We investigate the possibility of deriving the electron density fluctuations through de…
External Shear in Quadruply Imaged Lens Systems
Gilbert P. Holder, Paul L. Schechter
We use publicly available N-body simulations and semi-analytic models of galaxy formation to estimate the levels of external shear due to structure near the lens in gravitational l…
Constraints on Omega_m, Omega_L, and Sigma_8, from Galaxy Cluster Redshift Distributions
Gilbert Holder, Zoltan Haiman, Joseph Mohr
We show that the counts of galaxy clusters in future deep cluster surveys can place strong constraints on the matter density, Omega_m, the vacuum energy density, Omega_L, and the n…
