Reconstructing Baryon Oscillations: A Lagrangian Theory Perspective
Nikhil Padmanabhan, Martin White, J. D. Cohn
Recently Eisenstein and collaborators introduced a method to `reconstruct' the linear power spectrum from a non-linearly evolved galaxy distribution in order to improve precision i…
The Clustering and Host Halos of Galaxy Mergers at High Redshift
Andrew R. Wetzel, J. D. Cohn, Martin White
High-resolution simulations of cosmological structure formation indicate that dark matter substructure in dense environments, like groups and clusters, may survive for a long time.…
Simulating Subhalos at High Redshift: Merger Rates, Counts, and Types
Andrew R. Wetzel, J. D. Cohn, Martin White
Galaxies are believed to be in one-to-one correspondence with simulated dark matter subhalos. We use high-resolution N-body simulations of cosmological volumes to calculate the sta…
Constraints on the correlation between QSO luminosity and host halo mass from high-redshift quasar clustering
Martin White, Paul Martini, J. D. Cohn
Recent measurements of high-redshift QSO clustering from the Sloan Digital Sky Survey indicate that QSOs at z~4 have a bias b~14. We find that this extremely high clustering amplit…
