A Linear Perturbation Theory of Inhomogeneous Reionization
Jun Zhang, Lam Hui, Zoltan Haiman
We develop an analytic approach to study inhomogeneous reionization on large scales by solving the equations of ionization balance and radiative transfer to first order in perturba…
On Random Walks with a General Moving Barrier
Jun Zhang, Lam Hui
Random walks with a general, nonlinear barrier have found recent applications ranging from reionization topology to refinements in the excursion set theory of halos. Here, we deriv…
Isolating Geometry in Weak Lensing Measurements
Jun Zhang, Lam Hui, Albert Stebbins
Given a foreground galaxy-density field or shear field, its cross-correlation with the shear field from a background population of source galaxies scales with the source redshift i…
Intrinsic/Extrinsic Density-Ellipticity Correlations and Galaxy-Galaxy Lensing
Lam Hui, Jun Zhang
We compute both extrinsic (lensing) and intrinsic contributions to the (galaxy-)density-ellipticity correlation function, the latter done using current analytic theories of tidal a…
